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 — caffeine, screens, alcohol — 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 — 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 — 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 — 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 — 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.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Fixed a billing issue on the onboarding paywall where selecting the Monthly plan would start a Yearly subscription instead. Monthly now charges the monthly price.
