"I'm not sleeping." — Are you sure? Let's check the data.
Sleepa measures your sleep with Apple Watch, then uses AI to explain what is actually happening, in plain language. Developed with guidance from a sleep medicine specialist.
◉ AI ANALYZES YOUR SLEEP
One tap analyzes your last 30 days and explains the findings in clear, readable language.
• Breathing patterns — Reviews overnight blood oxygen levels and breathing events detected by Apple Watch
• Insomnia patterns — Evaluates sleep duration, time taken to fall asleep, and night wakings against established clinical criteria
• Compared to your own normal — Not against other people, but against your own baseline over time
You do not need to interpret graphs or numbers. Sleepa tells you things like "You have been sleeping less than usual lately." Read-aloud is supported, so you can listen instead.
Have a question? Ask the AI directly. "Why does this say caution?" "What should I do?" It answers based on your own results.
Every night also receives a sleep score from 0 to 100, calculated from duration, efficiency, sleep depth, breathing stability, and how often you woke up.
※ All analysis runs entirely on your iPhone. Your sleep data is never sent to an external server.
◉ REVEALING SLEEP STATE MISPERCEPTION
Even when you feel you are not sleeping, you may in fact be sleeping. This is known as sleep state misperception, and in these cases the problem is not a lack of sleep. The first step is to confirm objectively whether you are truly sleeping or not.
Sleepa's sleep diary records how you felt you slept, hour by hour, and displays it alongside what Apple Watch actually measured. The gap between the two is the key to identifying sleep state misperception.
Sleep can also feel insufficient even when its duration is adequate, if it lacks depth. Sleepa breaks your night into REM, Core, Deep, and Awake so you can see whether you are getting genuinely deep sleep.
Over time, patterns emerge — the nights you feel rested, and the nights you do not.
◉ AN ALARM THAT ACTUALLY WAKES YOU
Sleepa includes a powerful alarm.
• Sounds reliably even in Silent Mode and Focus Mode
• With snooze enabled, it repeats for up to 30 minutes until you press stop
• Use your own audio files (.mp3 / .wav) as your alarm sound
If you need to be certain you will wake up, this is for you.
◉ HOW TO USE SLEEPA
1. Set your alarm
• Like the built-in Clock app, it sounds in Focus Mode and Silent Mode

3. Check your sleep graph and score
