Sleep Tracker App for Simple, Focused, Hassle-free Sleep Tracking SleepSimple sleep tracker is a sleep tracking app designed to track your sleep duration starting from when you sleep and when you wake up. Instead of estimating sleep using motion or sound, SleepSimple sleep tracker app measures sleep duration using real time you control, giving you dependable data you can review long term. There are no wearables required, no background monitoring, and no accounts to manage. Open SleepSimple sleep tracker app before bed, tap once, and stop it when you wake up. Sleep duration is calculated instantly and stored in your history. This approach keeps sleep tracking simple while avoiding inaccurate automatic detection. Track sleep and naps accurately SleepSimple sleep tracker logs the essential information you actually need: • Bed time and wake time • Total sleep duration • Nap duration • Sleep and nap counts • Complete chronological sleep history If you forget to log a night, entries can be added or edited later without breaking statistics. Each session may also include optional notes so you can remember unusual nights, interruptions, or schedule changes. Understand patterns over time SleepSimple sleep tracker analyzes your sleep data and summarizes it in a clear format: • Daily, weekly, monthly and yearly averages • Total sleep time across any period • Custom date-range summaries • Sleep frequency and consistency • Simple sleep quality score based on your target duration Bar charts visualize changes over time without overwhelming detail, making it possible to understand trends even after months or years of use. Practical sleep insights SleepSimple sleep tracker provides helpful observations derived from your real sleep history. For example, SleepSimple sleep tracker detects when you have slept less than your normal duration multiple times in a row or when your schedule becomes inconsistent.

Verdict

The call

The clearest difference is rating: Sleep Diary at 5.0 against Sleep Tracker App's 4.5. Sleep Diary also leads on update cadence (every 4 weeks vs every 4 months) and iOS requirement (15.0 vs 17.6). Sleep Tracker App's advantage is ads (none vs shown) and review sentiment (100% vs 75%). On price, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Sleep Diary holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Sleep Tracker App has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Sleep Tracker App's written reviews are positive against 75% of Sleep Diary's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sleep Tracker App ships an update every 4 months, Sleep Diary every 4 weeks. Both last shipped on November 13, 2026.
