Short answer: raise your wrist, open AICHE on Apple Watch, tap the mic, and talk for as long as you need. The watch transcribes the recording, hands it to your paired iPhone over WatchConnectivity, and the cleaned-up note appears in every other AICHE app you're signed into.
The problem this solves
The best ideas show up between things. Walking the dog, in a checkout line, leaving a meeting, halfway down a stairwell. By the time you've pulled out your phone, unlocked it, found the app, and tapped record, the thought has already shrunk. Reaching for a wrist is faster than reaching for a pocket, and it's the difference between catching a thought and watching it dissolve.
How it works
- On your iPhone, install AICHE from the App Store and sign in. The Watch app installs alongside it once your iPhone and watch are paired. Your sign-in and settings sync to the watch via WatchConnectivity.
- On your Apple Watch, raise your wrist and tap the AICHE watch-face complication, or open the app from the app grid.
- Tap the mic button. Recording starts. There's no length cap - a 10-second thought and a 30-minute walk-and-talk both work.
- Talk naturally. The watch captures and transcribes the audio.
- Tap stop. The watch ships the audio and transcript to your paired iPhone over WatchConnectivity, Apple's official watch-to-phone framework.
- Your iPhone runs the cleanup pipeline (filler removal, punctuation, paragraph breaks) so what lands in your AICHE history is structured text, not raw dictation.
- From the iPhone, cloud sync (if you've enabled it) pushes the cleaned note to iPad, Mac, Windows, Linux, Chrome, and Obsidian within seconds.
WatchConnectivity sync, in plain terms
The Apple Watch app does not need its own AICHE subscription and does not operate independently of your iPhone. It rides on the phone. When the watch finishes a recording, it ships the audio and transcript to the paired iPhone using Apple's WatchConnectivity framework. If your phone is in your bag, in the next room, or just locked, the watch queues the handoff and completes it the next time the two devices see each other.
From there, your iPhone is the hub. Whatever sync settings you've configured on the phone (end-to-end encrypted cloud sync with your passphrase, or local-only) apply to watch recordings the same way they apply to anything else you record on the phone itself. Encryption at rest is AES-256-GCM with an Argon2id-derived key tied to a passphrase only you hold. We cannot read synced data on our servers. The watch is not a separate device with separate rules. It's another capture surface for the same account.
What "no length cap" actually means on a watch
Most watch-based voice apps cap recordings at 60 seconds or 5 minutes because storage and battery on a watch are tight. AICHE doesn't. Record a quick reminder or a 45-minute commute monologue, same workflow.
Two real constraints worth knowing about, since we'd rather you hear them from us than discover them mid-recording:
- Battery. Long recordings on the watch use the watch's battery. A 30-minute recording is fine on a fully charged Series 8 or later. If your watch is already at 15%, save the marathon thoughts for the phone.
- Handoff range. If you record a long session and your iPhone isn't in WatchConnectivity range when you stop, the audio stays on the watch and ships the next time the phone reappears. This is the same crash-proof model that protects desktop recordings: nothing is silently dropped. When you walk back into your house and unlock your phone, the queued recording arrives a few seconds later.
iOS only, and why
Apple Watch requires an iPhone for relay. There is no version of an Apple Watch that operates fully independently of an iPhone for AICHE, and we're honest about it. If your primary phone is Android, an Apple Watch recording surface isn't something we can offer. The Android equivalent is the home-screen quick-record widget, which is a one-tap surface on your phone rather than on your wrist.
If you carry an iPhone and an Apple Watch, this is the lowest-friction capture surface AICHE has across the whole product line. Lower than the desktop hotkey, lower than the mobile mic button. The hand you're already using to check the time becomes the hand you use to capture a thought.
Where this fits in your day
The Watch recording surface is built for the moments when typing wouldn't have worked and pulling out a phone would have lost the thought:
- Walking between meetings and dictating the follow-ups before they evaporate.
- On a run, capturing the shape of a problem you can't stop chewing on.
- In a parking lot, recording a debrief while it's still fresh.
- In bed, talking out tomorrow's plan without lighting up a phone screen.
- Standing in a hallway after a difficult conversation, getting the details into a note before the next thing pulls your attention.
In each case the alternative is "I'll type it up later." Later doesn't happen. The thought either gets captured at the moment it arrives, or it's gone.
Tips
Add the complication. Put AICHE on your watch face as a complication. One tap from raising your wrist to recording, instead of swiping through the app grid.
Trust the queue. If your phone is out of WatchConnectivity range when you stop recording, record anyway. The watch holds the audio and ships it the next time the phone is nearby. Treat the watch as if it always works, because in practice it does.
Pair it with cloud sync. If you've turned on end-to-end encrypted cloud sync on your iPhone, watch recordings end up on your iPad, Mac, Windows, Linux, Chrome, and Obsidian surfaces too. You record on the watch on the way to your desk; by the time you sit down, the text is waiting in your AICHE app on the desktop.
Use it for the quick stuff. Five-second reminders, two-sentence ideas, names you don't want to forget. The point isn't to replace your desktop dictation; it's to make sure the small thoughts don't slip through. The big ones tend to come back. The small ones don't.
Charge your watch overnight. Heavy voice use is roughly the same load as a long phone call. A nightly charge keeps it ready for the next day's capture.
Result: the gap between having a thought and getting it into a system you trust shrinks from "find a keyboard" to "raise your wrist." A typical capture is under 5 seconds of setup plus however long you talk, with no length cap to plan around.
Do this now: install AICHE on your iPhone, add the watch complication to your watch face, raise your wrist, and record one sentence about something you've been meaning to write down for a week.
