SleepArc: Sleep Tracker

SleepArc turns last night into a number. Track your sleep, see a clear 0-100 score, and wake up gently with a smart alarm - all 100% offline. No account, no server, no subscription.

WHY SLEEPARC
Popular sleep apps are powerful but locked behind subscriptions, and the free one-time options only exist on one platform. SleepArc fills the gap: both iOS and Android, one-time purchase, fully offline, lightweight.

KEY FEATURES
• Overnight tracking - tap Start at bedtime; mic and motion sensor detect snoring and tossing on-device
• Sleep score - a clear 0-100 rating for every night from duration, timing and regularity
• Smart alarm - wake in your lightest sleep window so mornings feel easier
• Trends - weekly and monthly charts, score line, bedtime consistency and sleep-debt graphs
• History & ranking - per-night log with best/worst nights and night-event details
• Export & share - back up your data and share a summary card
• Bedtime reminders and a relaxing sleep timer
• Web viewer - open your sleep log in a browser on the same Wi-Fi, password protected

PRIVACY FIRST
Everything is stored locally on your device. No account, no sign-up. Your sleep data never leaves the device - only the ad SDK uses the network. Audio is analysed on-device for loudness only and no recording is saved. Night events are estimated on-device and never uploaded.

ONE-TIME UNLOCK
Use the core tracker, score and smart alarm for free. Unlock Premium once for unlimited history, full trends, advanced insights, widget and backup. No subscription. The free version is supported by ads; the one-time purchase removes them.
