## What is MindSleep?

Every nap deserves to be taken seriously.

MindSleep is a sleep app built around AI-powered analysis of naps and daytime sleep. With fully automatic Apple Watch tracking and advanced AI analysis, every nap becomes meaningful health data.

Whether it's a 20-minute power nap at noon or a short doze in the evening — MindSleep captures it, analyzes it, and tells you what it means.

[AI NAP & DAYTIME SLEEP ANALYSIS]
A carefully trained on-device AI automatically detects and logs every nap. The new AI engine goes deeper: How good was this nap? How much did your body recover? What's your ideal way to nap? All data syncs to Apple Health — your 24-hour sleep companion.

[FULLY AUTOMATIC NIGHT TRACKING]
Wear your Apple Watch to bed and MindSleep tracks your entire night. Wake up to a complete sleep report — no buttons, no manual input.

[IN-DEPTH SLEEP ANALYSIS]
Multi-dimensional insights powered by professional AI algorithms: sleep score, efficiency, stages (Deep / Core / REM), time to fall asleep, awakenings, and consistency — so you can understand your sleep and improve it.

[CLEAR, BEAUTIFUL CHARTS]
No walls of numbers. Just clean, actionable insights at a glance.

[PERSONALIZED RECOMMENDATIONS]
Tailored suggestions based on your own data, helping you build healthier sleep habits over time.

*Note: MindSleep requires Apple Watch sleep tracking.
*Core nap & sleep tracking is free. MindSleep Pro unlocks AI-powered deep analysis.
