# Sleep Tracker App vs Sleep Diary

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.

Both are free to download. Sleep Tracker App sells 1 one-off in-app purchase and Sleep Diary sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

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.

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