The snooze feature should be eliminated however ### 3/5 — Réveil plus brutal qu'avant *2025-10-18, version 2.8* Depuis quelques semaines (iOS 26?), le volume de l'alarme est au maximum et non plus graduelle. Le réveil est par conséquent plus brutal qu'avant. ### 1/5 — Doesn't work *2025-08-09, version 2.7* I have used this several times and never been able to see the results, that this app claims to do. ### 1/5 — Always disconnects headphones. *2025-06-29, version 2.7* I want to nap will listening to another app. So this app is useless to me. ### 1/5 — Can’t get past “consent needed” message *2024-08-19, version 2.7* Can’t get past “consent needed” message on startup, suggesting I have a weak internet connection. After many attempts over several days to get past this I have given up and deleted the app as it is literally not usable. Which is disappointing. ### 1/5 — Cannot use *2024-05-24, version 2.7* The app is stuck on the "consent needed" screen, despite having an Internet connection. ### 4/5 — Happy Nappy Appy *2024-05-17, version 2.7* It’s a good nap, App I like it. I just wish it had how much sleep you’ve had. I don’t know what the clock thing means. I guess if it’s on the 15 on the side or left, it’s a 15. I wish I had how much sleep you had when you wake up you see it easily. ### 4/5 — 仮眠にいい *2024-01-23* やさしい音楽で起こしてもられていいです。設定ボタンが少し意味不明のところがあります。 ### 4/5 — Finally…A good Nap app *2023-08-25, version 2.4* First of all… meant to tap the 5 star. I like the ‘sleep time’ readout of how much and IF I did sleep.(with 20 min nap—which are perfect for me) I sometimes feel I didn't actually fall asleep — this is able to let me see that I did. *just now I felt I didn't sleep at all— but I feel SO much better, and yeah, the app shows I actually slept 27 of the 20 min. -Perfect! Time to go crush! ### 2/5 — J’aime bien mais… *2023-08-11* J’aime cette application mais… Elle est un peu incomplète, à la fin de notre siècle un graphique nous est proposé, mais aucun historique nous permet de retrouver ceux-ci pour nous permettre d’évaluer nos siestes, donc nos progrès de façon à nous en rendre compte. Pourquoi ne pas partager nos siestes avec l’application santé de l’iPhone ? Merci 🙏 ## Frequently asked questions about Power Nap Tracker ### What does Power Nap Tracker do?
