### 1/5 — スヌーズに異常

*2026-08-02*

アラームを止めたはずなのにうけつけていない
止めたのになり続けるエラーが起きた時間の無駄なので止めたら止まるようにしてほしい

**Developer response:** スヌーズ機能は正常に動作しています。アプリ内のお問い合わせからご連絡ください。喜んでお手伝いいたします。

### 3/5 — 設定に時間はかかるようになった

*2026-06-12*

ソフト自体はとても良いのですが、セット時ソフト導入宣伝一旦移行されるのは毎日うんざりしています　欲しい時には検索するから余計なお世話です検索す

**Developer response:** ソフトをとても良いと言っていただけて、うれしく思います。アラームの設定方法やアプリの動作に変更はありません。アプリを開いて「スリープ」をタップするだけで、前回設定したアラーム時刻がそのまま使われます。

一度限りの少額のお支払いで、広告を非表示にし、750種類のサウンドやカスタム起床シーケンスをご利用いただけます。

### 5/5 — Gerade für kleines Geld die werbefreie Version geholt

*2026-02-18*

Ich hatte Sleep Cycle bis heute genutzt, leider gab es dort immer mehr Einschränkungen und immer mehr Werbung trotz einmaliger Bezahlung.

Bei dieser App scheint alles zu stimmen, sogar die Restzeit bis zum Aufwecken wird angezeigt.

### 1/5 — 振動しなくなった

*2025-10-03*

アップデートしたら振動しなくなった。サウンドのみ。なぜ？

**Developer response:** 最新バージョンのアプリをダウンロードしてください。そのバグは修正されました。

### 5/5 — Duidelijke app!

*2025-09-20, version 3.6*

Heel fijne app, simpel, maar dat is juist goed!

### 5/5 — Tolle Schlaf App

*2025-07-18*

Funktioniert einwandfrei. Zeichnet auf wie viel man schläft und auch wenn man Geräusche macht.

### 3/5 — ヘルスケアとの連携機能は無いが優秀

*2025-04-07*

ヘルスケアとの連携機能は個人的に非常に重要なので星3ですね…

### 3/5 — Meer van verwacht

*2025-03-02, version 3.6*

Ik zie enkel uren slaap en wakker.. jammer dat het niet geluiden etc opneemt 
De Balken zijn wel duidelijk. Nog even verder afwachten

### 1/5 — Sleep Science

*2024-10-18, version 3.6*

Not accurate at all. I used the app because I have a life endangering medical condition and wanted to have record of my sleeping habits, but this app is FOR ENTERTAINMENT purposes only. Please do not use it if you want RELIABLE info!

### 1/5 — Плохое приложение.

*2024-08-07*

Плюсы: 1. Бесплатное 2. Можно загрузить бесплатные звуки природы Минусы: Интерфейс далёк от удобного. Справка - это скорее описание возможностей. Не удаётся найти, где в отчёте о сне находятся записанные звуки. Обратился в техподдержку, написали про «значок над графиком». Я всё обнажимался, все значки какие есть, включая сам график, нет никакой записи. Говорят, что не сохраняют записи на устройстве, чтобы не занимать место. Ребята! Чтобы не занимать место, просто дайте возможность хранить, листать, слушать и УДАЛЯТЬ записи и проблемы не будет. В общем платить за это приложение было бы глупо.

**Developer response:** После отмены будильника нажмите значок волны, чтобы прослушать самый громкий звук. Приложение включает бесплатный будильник с высококачественными звуками окружающего мира и отслеживание сна.
