Return
Two questions. Seventeen health signals. Why some days feel like yours.
Get Return
Out of beta. On the App Store.
The App Store is the only place to install Return. Telegram is where release notes and feedback live.
What Return does
A quieter way to understand your days.
Two taps a day, and the sensors you already wear. Everything else happens on the device.
One
Two questions. Not a questionnaire.
Rate your willingness and your control. Ten seconds, twice a day — that is the whole input.
It is enough for a transparent model, grounded in forty years of self-determination research, to start finding the pattern.
Two
It reads what your Watch already knows.
Sleep, HRV, mindfulness, activity — up to seventeen Apple Health signals you are already generating.
No extra logging, no second wearable, no new habit to keep up.
Three
See why, not just what.
A score on its own tells you nothing you did not already feel.
Return surfaces the three factors — out of seventeen health signals and daily contexts — that actually moved your autonomy, and by how much.
The screens
Seven screens, one question: how much of today was yours?
Dark follows your evenings, light follows your mornings — Return ships both, in twelve languages.
On your wrist
Your Watch already knows your body. Return tells you what it means.
Three screens, glance-first. History, grids and charts stay on the phone, where a bigger screen makes them worth reading.
Record
Log it in three taps.
Willingness, then control. Three buttons each — low, mid, high — and it saves itself.
Then it locks for an hour, and stays locked if you leave the app or restart the watch. One honest reading a day beats ten anxious ones.
Estimate
An estimate, on your wrist.
When your phone's estimate is missing or more than a day old, the Watch runs your model's own coefficients against what it can read on-wrist, and labels the result Watch estimate so you know where the number came from.
It is honest about the gap: the Watch can fill about twelve of the model's twenty-three signals, and the rest fire the same missing-data flags the phone uses for anyone with sparse health data. A degraded reading, not a different model — and no prediction interval or written explanation, which stay on the phone.
Today
Today, at a glance.
The ring, your growth stage, the streak, and how much of the week you have completed — the same numbers and the same colour bands as the phone.
Underneath, one health figure that changes with the hour: last night's sleep in the morning, your steps through the day, your HRV in the evening.
-
Nothing is lost without your phone. Every entry is written to a queue on the watch before it is sent. An amber Offline pill shows while entries are waiting, and duplicates are discarded on arrival.
-
The Smart Stack learns your rhythm. It reads the last thirty days from the watch itself, finds the two hours you usually record, and surfaces Return around them. Under five entries it stays quiet rather than guess.
-
Four complications. Circular, corner, rectangular and inline — each showing today's score, with a trend arrow only when there is real movement.
-
Live sessions mirror across. A recording session in progress appears in the Watch Smart Stack. Needs watchOS 11 or later paired with iOS 18 or later.
-
"Hey Siri, record autonomy." Writes the entry without opening the app, in ten languages, whether or not your phone is in range.
-
It reads the Watch's own sensors. Steps, exercise minutes, resting heart rate and sleep stages come from the watch directly, not relayed from the phone.
Inside Return
More than two questions.
On your home screen
Widgets, Dynamic Island, and Siri.
A glanceable score on Home Screen widgets, the Lock Screen, and in Dynamic Island.
"Hey Siri, record autonomy" works hands-free and answers with a score card — your ring, today's count, your streak — right in the Siri surface. Quick-log buttons live in Control Center too.
Always private
On-device, end to end.
AES-256-GCM encryption with a key that never leaves your device's Keychain. Records stay local by default; iCloud sync is yours to switch on.
No telemetry. No Firebase. No cloud analysis. The App Store privacy label reads Data Not Collected, and it is accurate.
-
A What-If simulator. Move the sliders — sleep, HRV, exercise, mindfulness, noise, mood — and see how tomorrow might shift. Presets for an Ideal Day or a Recovery Day. The predictions come from your data, not averages, and every forecast carries an honest 80% range from your own history rather than a wishful single number.
-
Twelve languages. Traditional and Simplified Chinese with Hong Kong and Taiwan variants, English, Japanese, Korean, German, Spanish, French and Brazilian Portuguese. It follows your system language, and your region's date and clock formats always win.
-
A small circle, end-to-end encrypted. Share a weekly pulse with a few friends. Invites and encouragement cards send straight from iMessage, you choose exactly which signals each friend can see, and nothing readable ever sits on a server.
Data boundaries
Private by design, not by promise.
Local first
Every record, mood, note, and health metric is encrypted and stored on this device by default. With iCloud sync off, your data never leaves the device.
Apple Health
Sleep, HRV, and activity require explicit Apple Health permission. Optional mood write-back to State of Mind exists, but both directions are off by default.
iCloud sync
When enabled, your records and personal model weights sync through Apple iCloud across your devices. Apple Health-origin data is excluded from iCloud sync.
On-device AI
Apple Foundation Models run on-device on supported iOS and iPadOS releases. Off-device cloud AI is never used unless you explicitly turn on a separate toggle.
The model behind Return draws on forty-plus peer-reviewed papers across self-determination theory, sleep science, HRV, and psychophysiology. See the sources.
