Sleepal – A Must-Have Apple Watch App for Better Sleep
Sleep is essential to everyone. That’s why Sleepal not only tracks your sleep with scientific, objective data—but also listens to how you really feel.
With a proprietary scoring algorithm rooted in scientific standards, Sleepal analyzes your sleep quality across multiple metrics, while also recording your subjective experience. Through cross-analysis and smart insights based on CBTi (Cognitive Behavioral Therapy for Insomnia), Sleepal helps you pinpoint the root causes of your sleep issues and offers personalized, evidence-based improvement suggestions.
Understandable Sleep Scores
- Sleepal’s exclusive scoring system draws on validated sleep scales, including the Pittsburgh Sleep Quality Index (PSQI), to generate a clear, daily score based on multiple dimensions of your sleep.
- Every morning, you’ll receive a personalized Sleep Report, featuring your overall sleep score, sleep stages, consistency, and physiological data—all explained clearly.
Snore Detection
- Free, stored locally, never uploaded — just open and use.
Fully Automatic Nap Detection
- Apple Watch doesn’t natively detect short naps—but Sleepal does. It accurately tracks naps longer than 15 minutes.
- Once installed, naps are logged automatically and you’ll get a notification when you wake up—no manual input required.
CBTi-Based Smart Suggestions
- If something’s off with your sleep, Sleepal helps uncover the underlying causes by linking related metrics and applying CBTi principles to guide you with effective, science-backed solutions.
- Common issues? We’ve got tailored suggestions for that too:
- How can I reduce snoring?
- How do I increase deep sleep time?
- What if I keep waking up during the night?
Track Long-Term Trends
- Daily reports are useful—but long-term trends are crucial. Sleepal helps you spot real patterns of improvement by tracking changes over time.
- Monitor trends in sleep duration, efficiency, and regularity at a glance.
Correlate Sleep with Body Signals
- Sleepal links sleep data with physiological signals like heart rate, respiratory rate, and HRV, aligned with your sleep stages, helping you understand how your body responds during sleep.

Sleepal is now my daily life partner. This is so accurate for tracking my sleep. And the clean user interface made it so special.

Good app

Kinda odd that- while it does track impromptu naps, it doesn't incorporate it into your sleep total count. Regardless, I do like its design more than autosleep.
Developer Response
Thank you for your support! In the next version, naps that are close to the main sleep will be included in the daily report.update at May 5th: it supports writing back to apple health database now, enjoy~
Poor interpretation

As a Sleep Medicine provider your sleep stage break down does not make sense. Lay people couldn’t possibly try to understand what it means. For instance the usual amount of REM is 20-25%, I’ll have 1 minute of REM & it says normal. I think you should break down your definition of sleep stages.
Developer Response
Thank you for your feedback. Sleepal currently references the paper National Sleep Foundation's sleep quality recommendations: first report. We will continue collecting more research to further refine the reasonable range for REM sleep.
New: Wake-up alarms created from snore recordings now support custom ringtones and volume control.
Other: Fixed some known issues.
