Most sleep problems don't need a gadget. They need a mirror. Sleep Arc is an AI sleep coach that works without a wearable. Open the app each morning, log last night in ten seconds, and get one concrete, specific action for tonight. No lengthy questionnaires. No hardware to charge. THE LOG TAKES TEN SECONDS Tap in your bedtime, wake time, and a few quality tags โ€” caffeine, screens, alcohol โ€” and you're done. Sleep Arc identifies the single habit that's actually dragging your sleep down and surfaces the patterns hiding in your data. ONE ACTION PER NIGHT Each day, an AI coach trained on your last seven nights delivers one specific recommendation. Not a list. One thing. Consistent effort on one habit beats scattershot effort across ten โ€” every time. AI INSIGHTS, DAILY AND WEEKLY Sleep Arc writes you a plain-English summary of last night and a weekly rollup that calls out your single biggest lever. Ask the coach follow-up questions in chat or by voice, transcribed on-device. PAIRS WITH APPLE WATCH If you wear one, grant Sleep Arc access to Apple Health and it pulls in your sleep sessions, HRV, resting heart rate, and respiratory rate automatically. Apple Health data is read-only and never leaves your phone. If you don't wear a watch, that's fine โ€” Sleep Arc works just as well from the ten-second log alone. YOUR ACCOUNT, YOUR DATA Sign in with Apple or Google. Your logs sync encrypted across devices so you never lose a night. Delete your account from Settings any time โ€” it wipes every row, locally and in the cloud. TRACK WHAT'S WORKING The sleep score gauge shows where you stand today. Seven- and thirty-day trend charts make it obvious whether your habits are actually moving in the right direction. Tap any recent night to see the full breakdown with an AI insight for that specific day. DESIGNED FOR BEDTIME Red-light mode keeps the display safe for dark environments โ€” log at 11 PM without blowing your melatonin. The whole app works in portrait only and stays in dark mode throughout. Sleep Arc works with the iPhone you already own. No wearable subscription. No new hardware. No fluff. Download Sleep Arc. Log tonight. Sleep better tomorrow. SleepArc Pro โ€” auto-renewing subscription โ€ข Monthly: $5.99/month (1 month) โ€ข Yearly: $39.99/year (1 year, ~$3.33/month โ€” save 44%) Includes a 7-day free trial.

SleepKit measures your night and tells you what it actually knows. TRACK WITH YOUR IPHONE โ€” OR YOUR WATCH Put your iPhone on the nightstand and SleepKit records the night: how long you slept, how restless you were, when you drifted off. Wear an Apple Watch and it uses the watch's measured sleep stages instead of an estimate โ€” automatically, with nothing to set up. HONEST ABOUT WHAT IT MEASURES Every night carries a badge: measured on your watch, or estimated by your phone. Tap it and SleepKit explains what an iPhone on a nightstand can and cannot see โ€” someone else in the bed, a loud room, a night too short to show a pattern. If a night came out wrong, you can correct the times or leave it out of your averages. WHAT YOU GET EVERY MORNING โ€ข Sleep score with the full formula shown โ€” no hidden weighting โ€ข Sleep stages across the night: deep, REM, light, awake โ€ข How long you took to fall asleep, and your sleep efficiency โ€ข Snoring detection with recordings you can listen back to โ€ข Room noise in decibels FROM APPLE HEALTH Heart rate and its overnight dip, HRV, blood oxygen, breathing rate and wrist temperature โ€” each shown next to your own weekly average, with a plain answer to whether it is normal for you. WAKE UP GENTLY The smart alarm looks for a light sleep phase inside your wake window, so you are not pulled out of deep sleep. If no light phase comes, it still rings at your latest wake-up time. That time is a guarantee, not a suggestion. ON YOUR WRIST AND HOME SCREEN Start or end the night from the Apple Watch app. Widgets show last night's score on the home and lock screen. A Live Activity keeps the running night on your lock screen, so you always know it is recording. STILL EVERY SLEEP SOUND Rain, waves, fire, white noise, city and nature โ€” mix up to eight sounds, save your own mixes, set a fade-out timer. Nothing from the sound library was removed. FREE TO TRACK Recording your night, the score, the stages and the vitals are free and unlimited. Premium adds history beyond 14 days and widgets. PRIVACY Night recordings stay on your iPhone and are never uploaded. No third-party analytics, no advertising, no account.
