In a crowded room, isolait finds the one voice you came for, follows it, captions it, and remembers it next time — 100% on your phone, no internet required, unless you opt in to one optional feature.
The same walkthrough that's built into the app — two voices talking at once, then one voice, alone.
"Hey are we still on for coffee tomorrow morning? I was hoping nine, maybe ten o'clock would work for you."
"So, then he told me the meeting got moved to Thursday. Now I have to rearrange my entire afternoon."

This loops automatically — the real app times it to your own voice, not a fixed clock.
Straight from the app: lock a voice, point and track it by direction, translate live with Voyage, clean up and transcribe audio or video in Studio, know exactly who's talking — and now, with V2.2, record and transcribe from Direction Mode too.
Every feature runs locally on Apple's Neural Engine, with or without an internet connection — no server in the loop, and nothing leaves your phone unless you opt in to Enhanced Transcription, an off-by-default setting.
Tap the mic to sample any voice nearby. Isolait captures a unique voice fingerprint in seconds, then locks onto that speaker — filtering out background noise and every other conversation in the room.
Point your phone at the person you want to hear. Isolait combines your device's heading with microphone beamforming and voice fingerprinting to isolate not just a voice, but the direction it's coming from. New in V2.2: record a session and capture a live transcript, just like Voice Lock — and it's now free for 30 minutes a day. Currently supported on your iPhone's built-in mic; AirPods support is coming in a future update.
Point your phone at someone speaking another language and hear it translated back, live and entirely on-device — no typing, no server round-trip, nothing leaves your phone. (The first time you use a new language, iOS may download its language pack; after that it works offline.) Save and export the session right on the spot. An experimental two-way Conversation Mode lets you and the other person each speak your own language, both sides translated as you go. Free every day, with a daily time cap.
Bring your own audio and video into Isolait, not just what you capture live. Import a video from your camera roll, an audio file from Files, or film one right in the app — then run on-device AI Clean Up to strip background noise, with an optional Transcribe toggle for a speaker-labeled transcript you can translate and export too. Longer imports now show real progress through Clean Up, Transcribe, and Identify Speakers, instead of just a spinner.
Built for podcasts, interviews, and any recording with more than one voice. Isolait labels who's speaking in a Studio import or a Voice Lock recording — anyone you've saved a Voice Profile for gets their real name, everyone else gets "Speaker 1," "Speaker 2," and so on. Entirely on-device.
Watch your audio environment come alive with a real-time visualizer — see exactly what's coming in, and exactly what isolait is sending back out.
Get a live transcript of your locked speaker only — cross-talk and background noise stay out of your notes, not just out of your ears. Voice Lock and Direction Mode transcription now run on Apple's newest on-device speech model, with noticeably better accuracy on fast or overlapping speech — and nothing sent anywhere to make it happen. Read a long or multi-speaker transcript full-screen, at whatever size is easiest to read.
On fast or overlapping speech, on-device recognition can miss words. This opt-in setting — off by default, and switched on one recording at a time — lets you choose more complete, off-device transcription when you want it. It's the only feature in the app that uses an internet connection. Voice isolation and cleanup always stay on-device, no matter what.
Lock a voice once and keep it. Isolait remembers the voices that matter so you can drop back into a lock in a tap, no re-sampling required.
Switch between your iPhone's mic, AirPods, or any connected Bluetooth headset right in the app — isolait detects what's available and adapts to whichever one you're using.
See who's locked in and control isolait right from your lock screen or AirPods — no need to keep the app open or your phone unlocked.
Say "Hey Siri, start listening" to lock in hands-free, or tap a Home Screen widget to jump straight into a lock — isolait meets you wherever you already are.
Isolait is 100% on-device unless you opt in. It runs on Apple's Neural Engine and needs no internet connection — use it anywhere, any time, with no signal at all. No audio is uploaded, stored, or shared; the only exception is Enhanced Transcription, which stays off unless you turn it on for a specific recording, and even then goes only to Apple's Speech Recognition service, never to us. Voice isolation and cleanup never leave your phone, full stop.
A full, searchable guide to everything Isolait can do, built right into the app — no more digging through settings to remember how a feature works.
Isolait works best when you're focused on a single nearby speaker. Performance in very loud or highly reverberant environments will vary — Isolait is built to help you hear better, not to replace a hearing aid.
The full engine works on Free — Voice Lock, Direction Mode, and Voyage's live translation, every day, with daily time caps that V2.2 just raised. Isolait Pro removes the caps and unlocks unlimited recording, Studio, AI cleanup, and translation — straight from the same paywall in the app.
Try Isolait Pro free for 7 days — cancel anytime during your trial and you won't be charged. After the trial, Isolait Pro auto-renews monthly at $4.99 unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings > Apple ID > Subscriptions. Payment is charged to your Apple ID at confirmation of purchase.
Most "AI" voice tools mean a round trip to a server. Isolait is 100% on-device unless you opt in: every feature runs on your iPhone, works with no internet connection at all, and your audio is processed and discarded locally, every time. The only thing that ever uses a connection is Enhanced Transcription — an optional setting that's off by default, that you switch on one recording at a time, and that sends audio only to Apple's own Speech Recognition service, never to Isolait. (Voyage may download a language pack from Apple the first time you use a new language — a one-time download, and none of your audio goes with it.)
V2.2 is out — faster, more accurate transcription, Direction Mode that records, and more to do for free every day. Start Isolait Pro free for 7 days, and Voice Lock, Direction Mode, and Voyage's live, on-device translation are all free for everyone, every day.
Voice Lock and Direction Mode transcription now run on Apple's newest on-device speech model — noticeably better accuracy, especially on fast or overlapping speech. Requires iOS 26 or later.
Lock a direction, tap Record, and capture a session with a live transcript — matching what Voice Lock could already do. Recordings land in the same place, with the same transcript, clean up, translate, and export options.
Voyage free time doubled to 60 minutes a day, Voice Lock to 30 minutes a day, and Direction Mode now includes a free 30 minutes a day (previously Pro-only). Studio includes one free Clean Up per day, plus one free recording save to try before going Pro.
Studio imports and Voice Lock recordings can now label who's speaking. Anyone you've saved a Voice Profile for gets their real name; everyone else gets "Speaker 1," "Speaker 2," and so on. Built for podcasts, interviews, and any recording with more than one voice.
Read a long or multi-speaker transcript at a larger, adjustable size, right from the transcript header.
A percentage through Clean Up, Transcribe, and Identify Speakers — instead of just a spinner — so a longer import never looks stuck.
On fast or overlapping speech, on-device recognition can miss words. This setting lets you choose more complete, off-device recognition for a specific recording, one at a time. Voice isolation and cleanup always stay on-device.
Video importing in Studio is more reliable, and transcripts are more complete on recordings with multiple speakers or natural back-and-forth conversation.
Import a video from your camera roll, an audio file from Files, or film one right in the app, then strip background noise with on-device AI. Turn on Transcribe for a speaker-labeled transcript you can translate and export too.
A full, searchable guide to everything Isolait can do, right in the app — a real tab now, not a buried settings page.
Refreshed navigation and simpler wording throughout Direction Mode and Voyage — the app should feel as clear as it sounds.
Video imports in Studio no longer stall on longer or higher-resolution clips, new recordings sort newest-first every time, and Clean Up previews load reliably.
Start your trial right from the paywall — no charge until it ends, cancel anytime in Settings.
Hold your phone up to anyone speaking another language and hear it translated back live, entirely on-device. An experimental two-way Conversation Mode covers back-and-forth exchanges, each person hearing their own language.
The paywall now shows every Pro benefit at a glance — including AI Clean Up, transcript translation, and unlimited Voyage — instead of requiring a scroll to find them.
Export a recording's audio and its formatted transcript together, straight from the app — one tap, no extra steps.
Translate a locked-in transcript into roughly 20 languages, entirely on-device — nothing sent anywhere to get translated.
Already have a noisy recording? Strip out room tone, traffic, and hum after the fact, processed entirely on your iPhone.
Unlimited Voice Lock, unlimited Direction Mode, unlimited saved profiles, and recording & export — $4.99/month, auto-renewing.
A live audio pipeline separates voice-range signal from ambient noise as it happens — no lag, no buffering.
Once locked, isolait holds onto that speaker's fingerprint through movement, crosstalk, and changing background noise.
When someone else cuts in, isolait's recovery is noticeably quicker now — roughly half the time to fully re-lock onto your target voice.
Every word from your locked-in voice appears as text in real time — transcribed on your phone by default, never sent anywhere else unless you opt in.
Transcripts note who's speaking, so multi-voice recordings are easier to follow — and since Identify Speakers, saved voices get their real names.
Pick between your iPhone's built-in mic, AirPods, or any connected Bluetooth headset — isolait detects what's plugged in and lets you switch on the fly.
Build a personal library of voices you've locked before, and drop back into them instantly — no re-sampling required.
Lock screen and AirPods controls let you see who's locked in and pause or resume without unlocking your phone. Say "Hey Siri, start listening" for a hands-free lock, or tap the Home Screen widget to jump straight in.
The live lock-strength meter shows up in caption/reader view too, instead of being hidden behind the transcript.
Your phone's heading helps bias toward whoever you're physically facing — useful the moment you walk into a noisy room. For now, Direction Lock is limited to your iPhone's built-in mic; AirPods support is coming in a future update.
The core engine is just the beginning. We're building toward something bigger — and every chapter ships when it's ready, not before.
A guided first launch and per-device tuning, so isolait locks in perfectly whether you're on your phone's mic or your headphones.
Isolait starts understanding more than just one voice at a time — tracking and separating multiple speakers as a conversation moves around you.
Record a room instead of just one voice, then pull any single speaker back out of it afterward, cleanly.
The same engine, built to go wherever your voice needs to follow.
