The best private transcription apps for iPhone.

One sentence, and everything is ordered by it

A ranking without a stated criterion is just an opinion with numbers glued on. So here is the one this page uses, before you read a single position:

That criterion decides everything. It puts a free Apple app above several paid ones. It drops the best-reviewed app in the category, with 75,000 ratings and an Apple Editors’ Choice badge, to last place. And it puts a one-person Dutch app first, which is exactly why you should check the criterion is one you care about before you trust the order.

On a different criterion, a different app wins, and this page says which one. If you need captions appearing while somebody is still talking, Otter or Notta win and mine does not compete. If you need a bot to attend a Zoom call you are not in, Otter, Notta and Fireflies win. If you need human-verified accuracy, Rev wins at $1.99 per minute and no on-device model touches it. If you are editing a podcast, Descript wins and is barely the same product. Those are real answers to real questions; they are just not this question.

Four things had to be true for a high position: the speech model runs on the device, there is no account, you pay once or nothing at all, and the app still does the whole job afterwards, meaning you can get the text back out in a usable form.

All thirteen, side by side

Scroll the table sideways on a phone; the app column stays put. “Unconfirmed” means exactly that: the vendor does not publish it and I would rather leave a hole than fill it with a guess.

One honest note about the CarPlay column. Every app in this table except mine answers “No”, but CarPlay recording is not mine alone. Auto Memo Recorder has had it since March 2025, and Cleft and Memo AI both shipped it in 2026. They are not ranked here because they are voice-note apps rather than transcription apps, but the column would mislead you without this line.

The ranking, one to thirteen

Positions one to five are all genuinely on-device, one-time-payment apps with no account, and within that group the order is by how much of the transcription job each one finishes. Six and seven are the honest edge cases. Eight and nine run locally but charge monthly or cannot be verified. Ten to thirteen are cloud services, ordered by how much of the criterion survives.

1. 1

   Just Transcribe

   The Dutch Logic Co. · iPhone, iPad, Apple Watch, CarPlay

   The only app here that keeps the whole chain on the phone: recording, transcription, speaker names, translation and the summary. Ten speech models you pick and delete yourself, nine of the Whisper family plus NVIDIA’s Parakeet v3. Fifty transcription languages, on-device translation into 55, export to SRT, VTT, PDF and text. One payment, no account, no analytics, and an App Store label that reads Data Not Collected. Every rival below finishes somewhere short of that line, either by uploading a step or by not offering it.

   Price

   Free download, Tiny and Base models free forever, EUR 7.99 once for everything else. No subscription, no ads.

   The limitation

   No live captions: the transcript arrives when you stop, not while somebody is still talking. No meeting bot, no team workspace, no sync between devices, Apple platforms only. Large v3 Turbo alone needs 954 MB free. And it has no App Store ratings yet, where Otter has 75,000.

   Pick it if

   You want the audio, the transcript, the speaker names and the summary to stay on your own iPhone, pay once, and still work in airplane mode. Journalists protecting sources, therapists, lawyers, doctors, HR, researchers — anyone recording conversations they are not allowed to upload.

2. 2

   Whisper Notes — Speech to Text

   SmashMelon LLC · iPhone, iPad, Mac

   The closest genuine rival, and a good app. Fully on-device transcription with real on-device speaker separation for $7.99 once, three model families to switch between, and a vendor who documents the limits rather than hiding them.

   Price

   $7.99 one-time, covering iPhone, iPad and the Mac App Store build. No in-app purchases.

   The limitation

   No iCloud sync at all — the vendor calls it a deliberate privacy decision and warns that deleting the app deletes your recordings. No real-time transcription, AI summaries are Mac-only, transcription stops if you leave the app, and there is no CarPlay or Apple Watch support.

   Pick it if

   You want offline transcription with on-device speaker labels at the lowest one-time price, are happy exporting by hand, and do not need CarPlay, Watch or on-device translation.

3. 3

   Aiko

   Sindre Sorhus · iPhone, iPad, Mac, Vision Pro

   The purist’s option: Whisper running locally, a zero-collection privacy label, and a long-standing independent Apple developer behind it. One purchase covers the Mac too, which no other app in this comparison manages.

   Price

   $24.00 one-time, Universal Purchase across iPhone, iPad, Mac and Vision Pro. Free 14-day full-feature trial with no auto-charge.

   The limitation

   No speaker detection at all — the App Store description states plainly that it does not currently have it. No live transcription, no in-app text editing by design, it must stay in the foreground on iOS, and it ships as a fixed 1.8 GB bundle whose languages cannot be trimmed.

   Pick it if

   You want the same $24 to cover a Mac running Whisper large-v2, and you transcribe single-speaker audio — lectures, dictation, one-voice interviews — where knowing who spoke does not matter.

4. 4

   Hello Transcribe

   iPhone, iPad

   The most transparent model story on iPhone. Published speed and word-error-rate tables for every model it ships, free Tiny, Base and Small presets, and any Whisper model you like once you pay. Its audio-persistence trick means you can re-transcribe an old recording later with a better model, which genuinely improves your archive retroactively.

   Price

   Free with Tiny, Base and Small. $6.99 one-time PRO unlock. The App Store listing also shows a $1.99 “Pro Subscription” item with no stated billing period.

   The limitation

   No speaker identification anywhere in the app. The accurate large-v3-turbo model is PRO-only and needs an iPhone 15 Pro or newer, and the developer notes it is not fast enough for real-time dictation even there. Translation is English-only, and there are no summaries.

   Pick it if

   You want to see and choose the exact Whisper model, run real-time on-device dictation, and come back to old recordings with a better model later.

5. 5

   LocalWhisper

   iPhone · a dictation keyboard, not a transcriber

   The cheapest route to Whisper Large v3 quality on an iPhone, and the only app here whose audio is processed in memory and discarded by design rather than by setting.

   Price

   Free with a bundled model and no word limit. $4.99 one-time Pro unlock for Neural Engine acceleration and models up to Large v3.

   The limitation

   It is a keyboard. No file import, no transcript library, no export formats, no summaries, nothing to share afterwards — text goes straight into whatever app you are typing in. It also has only two App Store ratings, so real-world reliability is unverified.

   Pick it if

   What you actually need is private dictation into any app’s text field rather than transcribing recordings. Power users can also point it at their own Whisper server over Tailscale.

6. 6

   Just Press Record

   Open Planet Software · iPhone, iPad, Mac, Apple Watch, Vision Pro

   The best pure recorder in this comparison and the best Apple Watch app in it, shipping since 2015. It drops below the apps above it for one sourced reason only: its transcription is Apple’s, not Whisper’s, and Apple’s can leave the phone.

   Price

   $6.99 one-time, Universal Purchase across iPhone, iPad, Mac, Apple Watch and Vision Pro. No in-app purchases.

   The limitation

   Not reliably offline. The developer’s own privacy policy states that depending on device capabilities and the language being transcribed, the audio may be uploaded to Apple’s iCloud servers for processing. No speaker identification of any kind, and transcription covers just over 30 languages.

   Pick it if

   You mainly need a superb unlimited-length recorder — stereo, 96kHz/24-bit external mics, standalone Apple Watch recording, iCloud Drive sync — and treat the transcript as a bonus rather than the product.

7. 7

   Voice Memos

   Apple · already on your phone

   Free, already installed, on-device, and genuinely good for a single-speaker memo. This is the honest baseline every paid app on this page has to beat, and plenty of people never need to beat it. Apple’s Notes goes further still: it is the only Apple built-in with documented speaker attribution, for recorded phone calls, and it summarises recordings for free on an Apple Intelligence iPhone.

   Price

   $0. Included with iOS. No account, no purchase, no in-app purchase.

   The limitation

   Exactly ten languages, iPhone 12 or later, no speaker labels, no way to import an existing audio file, and the only documented transcript output is Copy Transcript to the clipboard — no SRT, no VTT, no text file, no timestamps.

   Pick it if

   You record your own voice in English, Spanish, Portuguese, Italian, French, German, Japanese, Korean or Chinese on an iPhone 12 or later and want zero cost, zero setup and zero decisions. If that is you, stop reading and use it.

8. 8

   Whisperer: Local AI Transcribe

   Cem Cakmak · iPhone, iOS 26+

   On paper the widest on-device feature set here — model choice up to Large-v3-Turbo, local speaker separation, five export formats, and background processing that keeps running while you use other apps. In practice it is new, unproven and subscription-gated.

   Price

   Free tier. Pro at $5.99/month, $44.99/year, or $79.99 lifetime.

   The limitation

   Speaker detection, the Large models, advanced exports and background processing are all behind the subscription. It requires iOS 26.0, the steepest OS floor in this group, and holds a single App Store rating since its March 2026 release, so none of its claims are independently verifiable yet.

   Pick it if

   You specifically need on-device transcription that keeps running in the background while you use other apps — Aiko and Whisper Notes both stop when you leave — and will pay monthly or $79.99 once to get it.

9. 9

   Whisper Transcription

   Good Snooze · the iOS sibling of MacWhisper

   The one app that lets you choose per file between a private on-device model and a fast cloud engine. Useful flexibility, muddled pricing.

   Price

   Free download. In-app purchases listed at $6.99, $8.99, $29.99 and Pro Lifetime $99.99, plus an Assistant subscription at $5.99 weekly, $9.99 monthly or $89.99 yearly. Apple does not show which Pro tier is which billing period.

   The limitation

   The cloud path sends audio to Groq and caps files at 25 MB. The on-device path needs iPhone 13 or newer per the App Store, while the vendor’s own docs still say iPhone 15 or newer. Its privacy label shows usage data collected, unlike the zero-collection apps above, and it holds 3.85 stars from 158 ratings.

   Pick it if

   You have an older iPhone or long files and want to pick cloud speed for throwaway recordings and the local model for private ones, with a lifetime option instead of a subscription.

10. 10

    Whisper Memos

    iPhone, Apple Watch

    The best Apple Watch story in the category — a genuine standalone Watch app that records with no phone present — and a real speaker-separated meeting mode. But every word of your audio goes to a server.

    Price

    $10/month billed monthly, or $5/month billed $60/year. Free to try, but the vendor publishes no free allowance.

    The limitation

    Nothing runs on the phone. The privacy policy states that transcription entails transmitting your audio file to OpenAI, and the App Store label lists audio data linked to your identity. Memos are capped at 90 minutes each.

    Pick it if

    Your main capture device is an Apple Watch, or you want transcripts emailed automatically and routed into Notion, Things, Day One or a custom webhook.

11. 11

    Transcribe — Speech to Text

    DENIVIP · iPhone, iPad

    The best-established generic App Store transcriber, with the cleanest privacy label of its peer group and hour credits that never expire.

    Price

    PRO $14.99/month or $99.99/year. Business $59.99/month or $399.99/year. Or pay-as-you-go credits at $4.99 per hour, $29.99 for ten.

    The limitation

    File transcription is server-side and metered: the $14.99/month plan buys five hours of server transcription time per month. The free tier is a one-time 30-minute trial, not 30 minutes per month, and free-tier uploads are deleted from their server after two weeks. The vendor states its service is not HIPAA-compliant or court-certified.

    Pick it if

    You refuse subscriptions but want cloud-grade accuracy across 100+ languages. $4.99 buys an hour, $29.99 buys ten, and the vendor states the credits never expire.

12. 12

    Notta

    iPhone, iPad, Apple Watch, web

    The strongest cloud competitor that actually ships a native iPhone app: live subtitles, a meeting bot, 58 languages with translation into 42. None of it on your device.

    Price

    Free tier. Pro $8.17/user/month billed annually ($97.99/year). Business $16.67/seat/month billed annually. Enterprise from 51 seats.

    The limitation

    Live microphone speaker identification only works when the spoken language is Japanese — the help centre states it verbatim. The free tier caps each conversation at three minutes, so it cannot transcribe a single meeting, lecture or interview end to end no matter how large the monthly pool is. The App Store label lists identifiers used to track you.

    Pick it if

    You need a bot to join Zoom, Google Meet, Teams or Webex and transcribe calls you are not holding a phone in, live subtitles with picture-in-picture, or 58 languages.

13. 13

    Otter.ai

    Otter.ai, Inc. · iPhone, iPad, Android, web

    The most polished and best-loved notetaker on iPhone: Apple Editors’ Choice, 4.8 stars from about 75,000 ratings. It is last here purely because it is the clearest illustration of what the criterion at the top of this page costs you. On any question about live transcription, meeting bots or team collaboration, Otter beats everything above it.

    Price

    Free Basic. Pro $16.99/user/month monthly, or about $8.33/user/month billed annually ($99.99/year). Business $30/user/month, or $19.99 annually. Enterprise custom.

    The limitation

    Otter trains on your recordings by default. Its privacy policy lists as a purpose of processing the training of its proprietary AI on de-identified audio recordings and on transcriptions, which it notes may contain personal information, and no consumer-plan opt-out is published. The free tier is 300 minutes a month, 30 minutes per conversation, and three lifetime audio file imports — not three per month.

    Pick it if

    You are a team needing live streaming transcripts, bots that attend Zoom, Teams and Meet calls without you, AI search across a whole archive of past meetings, and shared workspaces with SOC 2 Type 2 and HIPAA posture.

Three features worth a closer look

These are the three things people write in about, and all three are easy to overclaim. So here is each one with the counterexamples included, because a comparison that hides them is worth nothing the first time a reader checks.

Recording from CarPlay

Just Transcribe puts a record button on the car screen. Tap it, talk, tap again, and the transcript is waiting on your iPhone when you park. Nothing is uploaded and nothing needs a connection, so this works in a tunnel or on a mountain road as well as it does in town.

It is rare, but it is not mine alone, and it never was. Auto Memo Recorder has offered CarPlay recording since March 2025, roughly sixteen months before this page was written. Cleft shipped it in May 2026 and Memo AI refined it the same month. It stays rare because Apple’s own CarPlay developer guidance says recording is generally not supported there, which is worth knowing before you build a workflow on it with any app. Apple’s Voice Memos has no CarPlay presence at all. What is uncommon in the combination is the rest of it: none of those three then gives you speaker names, a choice of ten speech models, on-device translation and subtitle export on the same one-time purchase.

Advanced Privacy, the session that keeps nothing

A lock in the top left corner of the main screen opens a mode that runs exactly one recording. It transcribes and summarises entirely on the phone, erases the audio the moment the transcript has been read out of it, and when you close the screen it discards the rest. Nothing enters your library. Export the summary before you leave or it is gone. Because the whole chain runs locally, the whole session works in airplane mode, which means this is a claim you can verify rather than one you have to believe.

Other apps do erase things too, and it is worth knowing how they differ. Fireflies has a Summary Only mode on its Enterprise plan that deletes both the audio and the transcript once the summary exists. Granola discards the audio after transcribing and keeps the notes. Otter can strip audio from conversations and auto-delete on a retention schedule, on Enterprise. The pattern in all three is the same: the audio goes to a server first, and the transcript stays. As far as I can establish, checked in August 2026 against App Store listings and vendor documentation, the whole chain running on the phone and then leaving nothing behind at all is still unusual. If you find another that does, mail me and this paragraph changes.

One deliberate piece of precision: “erased” here means the file is deleted and the app keeps no copy and uploads nothing. No app on iOS, mine included, can promise that unlinked flash storage is forensically unrecoverable, and you should distrust any that claims otherwise.

Speaker identification that never leaves the phone

Just Transcribe works out who is speaking on the device, and every voice you name goes into a library on that device. Save a colleague once and they are named automatically in later recordings, with no voiceprint ever leaving your phone.

Two separate things get confused here, so take them apart. On-device speaker separation — splitting a recording into Speaker 1 and Speaker 2 — has become common on iPhone during 2026: Whisper Notes, Transkript, MacWhisper for iOS and others all do it locally, and the open-source FluidAudio package means any developer can add it. A persistent named-voice library that recognises the same person across recordings is the less common half, and the best-known apps that offer it — Otter and Plaud — do the matching on their servers. It is the combination of the two, locally, that is uncommon. Not the individual halves, and not for ever: Lyonesse shipped on-device voice profiles in 2026 as well.

Where my own app loses, plainly

If this section were missing you would be right to distrust everything above it.

• ×
  Live captions. Words appearing on screen while somebody is still speaking. Otter, Notta, Trint and Rev all stream in real time. Just Transcribe gives you the transcript after you stop, and does not compete here at all.
• ×
  Meeting bots. Nothing on a phone sends an agent into a Zoom, Teams, Meet or Webex call you are not attending. Otter, Fireflies and Notta do, and it is a genuinely different job.
• ×
  Teams and sync. No shared workspace, no permissions, no comments, and nothing syncs between your devices — which is the direct cost of nothing being uploaded. You cannot have both.
• ×
  Human accuracy. Rev offers human transcription at a flat $1.99 per minute with a 99%+ guarantee. No on-device model delivers that at any price.
• ×
  Very long or very poor audio. TurboScribe handles ten-hour, 5 GB files in fifty-file batches. A phone on a battery has less thermal and power headroom, and that is an architectural limit rather than a marketing one.
• ×
  Language breadth. Happy Scribe claims 150+ languages, TurboScribe 98+, Notta 58. Just Transcribe covers 50, with on-device translation into 55.
• ×
  Apple only. No Android, no Windows, no web, no Mac app. If your team is mixed, this is the wrong tool.
• ×
  Enterprise paperwork. SOC 2 Type 2, ISO 27001, SSO, audit logs, EU data residency. A one-person studio does not have these and will not pretend to. Otter and Trint do.
• ×
  Wrist capture. Just Press Record records standalone on Apple Watch with unlimited length, and Whisper Memos runs on a cellular Watch with no phone nearby. Both beat mine there.
• ×
  Track record. Just Transcribe has no App Store ratings yet. Otter has about 75,000 and an Editors’ Choice badge. That is a real thing to weigh, and no argument on this page cancels it.

Two more that are simply fair to say. Sonix charges $10 an hour and Temi $0.25 a minute with a free first 45 minutes — if you transcribe two hours a year, either can cost less than any one-time purchase here. And Fireflies publishes an unusually explicit commitment not to use personal information for AI model training, alongside unlimited free transcription minutes. Not every cloud vendor is careless with your recordings; Trint, Sonix and Descript all publish no-training commitments too.

How this was checked, and how to check it yourself

Every number on this page was read on 27 August 2026 from one of three places: the app’s own App Store listing, the vendor’s published pricing or feature page, or the vendor’s support documentation. Listicles and affiliate round-ups were not used, because in this category they are routinely years out of date.

A note on names: there is a second, unrelated iPhone app called JustTranscribe. It is not this app and is not made by The Dutch Logic Co. If you are searching the App Store, this one is published by The Dutch Logic Co. under App Store ID 6777195989.
