Le réveil est par conséquent plus brutal qu'avant. ### 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 🙏 ### 4/5 — Retain the info? *2023-01-19, version 2.3* It would be nice to retain the information about how long I actually slept for a little while- maybe until I use the app again? I’m so tired today I didn’t remember it from one moment to another. My favorite, the best Sleep Cycle keeps it going back to the beginning. Granted, Power Nap doesn’t. I’ve picked up the sounds and apps advertised but still see their ads. I got the extras to get rid of the ads. ### 2/5 — 素晴らしい *2022-04-22* バッテリー駆動時間も遅くてとても使いやすいアプリ。 要望として、現在時間と残り時間が出るようになるといいそれと経過時間が計測中に出れば利用者が増えると思います 記録が0分というのは何を基準としてなのかはっきりして欲しいタイマーを起動して寝たはず。20分になっててもいいはずなのに記録なし。エラーなら直して欲しい。 **Developer response:** このアプリをお気に入っていただけて光栄です。フィードバックをありがとうございます！アプリ内の "ご質問またはフィードバック "からお問い合わせください。喜んでお役に立ちます！ ### 2/5 — Super mais… *2022-02-25* Super app, dommage qu’elle ne log rien dans Santé, regrettable en 2022… Esthétique et ergonomie à revoir également. ### 3/5 — Chill *2022-01-07, version 2.2* Chill ### 4/5 — まあまあ *2020-09-23* まあまあ。 宣伝がうざい。課金しても良いから消して欲しい。 出来は、満足 ### 4/5 — Great for my afternoon nap *2020-09-23, version 1.9* I’d like to use it without the ads but I can’t find the paid version for power naps ### 5/5 — Rain *2020-09-22, version 1.9* Finest ### 5/5 — Micro-siestes... *2020-07-04* PowerNap est une petite application gratuite, toute simple, vraiment performante et agréable. ## Most critical reviews (10 lowest-rated) ### 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. ### 1/5 — No review *2022-05-26, version 2.3* Until it works ### 1/5 — 役に立たない *2022-02-17* まったく1 秒として寝ていないのに勝手に寝たことにされ「目標睡眠時間にたっしました」とかでアラームが鳴る　途中でトイレに行ったりしてるのに、それすら感知されていない　感度はもちろん高にしてるのに。役に立たない　削除します **Developer response:** あなたの動きを検知できるところに電話を置いてください。アプリ内の "ご質問またはフィードバック "からお問い合わせください。喜んでお役に立ちます！ ### 1/5 — Terrible *2021-02-04, version 2.0* This earns 1 star and the title WORST NAP APP EVER when it doesn’t even wake you up when you told it to. Waste of my time. ### 1/5 — Works ok but so ads every nap is annoying *2019-09-10, version 1.6* Ads everywhere ### 1/5 — Erkennt Schlaf NICHT *2017-12-18* Ich habe mehrmals den ganzen "nap" wach gelegen, nur ruhig geatmet und mich wenig bewegt. Danach behauptet die app, ich hätte den großteil der zeit geschlafen. Sie kann also schlaf und wach nicht unterscheiden, wie ich es auch erwartet habe. Da sie ihren zweck damit gar nicht erfüllt, auch nicht ein bisschen, kein stern, wenn das möglich wäre. **Developer response:** Schlaf wird mit dem Beschleunigungsmesser gemessen. Bitte achten Sie darauf, dass das Handy richtig liegt (Button "Test" in "Einstieg") und testen Sie die App mit einem echten Nickerchen. ### 1/5 — Dishonest *2016-09-22* Tries to force you to buy the full version to get the alarm sounds. The free version says it has them - this is a lie **Developer response:** There are 24 alarm sounds in 13 categories and alarm sound sequences. After choosing a nap length, tap "Sound" under "Choose Sound". ## Most praised reviews (10 highest-rated) ### 5/5 — El Hefe *2026-03-12, version 3.0* Works amazing, somehow knocks you out almost instantly and wakes you when you set it. The snooze feature should be eliminated however ### 5/5 — Fantastic app *2023-07-13, version 2.4* Free, and I have found the nap timer and tracker both accurate and functional. Would recommend everyone to try this app to take effective 20 minute power naps without fiddling with their alarms and stuff, literally free and the ads are not too intrusive there’s nothing to lose. ### 5/5 — Life Changing *2022-08-28, version 2.3* I love naps but sometimes I oversleep. This app not only monitors my nap but has and alarm to wake you up. ### 5/5 — Handy and easy to use nap monitor *2022-08-16, version 2.3* This app’s simple, no clutter interface makes it easy to set up and use to monitor my nap and wake me gently with my choice of sounds when I want the nap to finish. Love it! ### 5/5 — Presque parfait *2021-11-10, version 2.2* Avec de doux sons pour le réveil, cette app eat ma préférée. Une version (payante?) sans publicité serait parfaite! ### 5/5 — Completely changed my life *2021-05-11, version 2.1* One of the worst things is oversleeping a nap or waking up super groggy from one. This app has allowed me to never experience those things again, I wake up from a nap and I feel great! Rested! ### 5/5 — Son - animation *2021-05-01* Bon appli mais le son devrais augmenter progressivement. Et manque d’animation quand on arête la sonnerie et que le résumé de la nuit s’affiche ### 5/5 — よいです。 *2021-04-06* 仮眠の時に、お世話になっています。 ### 5/5 — Helpful *2021-01-02, version 2.0* I need to use this more! ### 5/5 — Love this app! Here’s a suggestion.... *2020-10-20, version 2.0* Love this app! Would love a version for a full nights sleep that you select 8 hours and it wakes you up after 8 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
