About ALYN
ALYN turns what your ring records overnight into something you can actually use in the morning. Wear it to sleep. Wake up to a readiness score, a briefing in plain English, and one or two things worth doing differently today. No dashboards to decode, no jargon, no pressure. SLEEP See your night as it happened - time in bed, when you actually fell asleep, deep and REM stages, and the times you woke. Sleep debt that repays itself when you catch up, instead of accumulating into a number designed to worry you. RECOVERY AND READINESS Overnight heart rate variability and resting heart rate, tracked against your own baseline rather than a population average. Your readiness score explains itself: which signals moved, by how much, and what that tends to mean for you. BODY SIGNALS A quiet flag when several of your numbers drift together for more than a day - the kind of pattern worth noticing before you feel it. MOVEMENT Steps, calories and active minutes. Start a GPS walk, run or ride to see pace, route and heart rate - or record indoors and leave the phone behind. TRENDS Week against week, month against month, with a reflection each week that names what steadied, what climbed, and one gentle thing to carry forward. CYCLE - OPTIONAL Predicted phases and next period, built from your own logged history. Prediction-based, and always described that way. Off by default; turn it on if you want it. THE BODY CLARITY SYSTEM Your day's numbers become a short written briefing each morning. It only ever uses figures your own ring recorded. NO SUBSCRIPTION. EVER. You bought the ring. The app is yours. Every feature, every day - no tier above you, nothing held back behind a monthly fee. REQUIRES AN ALYN SMART RING This app is the companion to the ALYN ring and needs one to work. alynring.com ALYN is a wellness product, not a medical device. It does not diagnose, treat, cure or prevent any condition. If something about your health concerns you, speak to a qualified health professional.
What’s new
Version 1.0.42 · Updated October 19, 2026
Sleep that reads the way your night felt. - Sleep stages are now checked against how you moved, so deep and REM sleep are no longer over-counted and your sleep score is more honest. - A calmer sleep chart. Rolling over in your sleep no longer shows as waking up. Only real wakes are drawn, and nearby ones are joined into one. - Wakes in words: how many times you woke, when, and any restless stretch. - Detected workouts can be edited. Tap Edit to set the activity and the real length, on the card, the review screen or a saved workout. - iPhone: walks your ring picks up on its own now appear in the app. - Keeps your ring connected after an app update, even when ALYN is closed. - Fixes duplicate nights in Health Connect.
