### 1/5 — Keine Spiegelung der  Benachrichtigungen

*2025-07-03*

Die App bietet keine Möglichkeit die Benachrichtigung zur Schlafenszeit auf die AppleWatch zu spiegeln, da es eine “Interne Benachrichtigung der App” sei. Was auch immer das bedeuten mag. Also falls ihr sie dafür nutzen wolltet, nicht brauchbar. Falls sich das ändert werde ich meine Rezension angleichen.

### 1/5 — Does not work.

*2025-02-11, version 2.0.7*

I tried a few times and each time the alarm went on after I was already up and out of bed for 10 or more minutes

### 1/5 — Rip off!

*2024-11-23, version 2.0.7*

It doesn’t work on my Apple Watch. Don’t waste your money. I couldn’t get a refund.

### 1/5 — No longer works

*2024-02-04, version 2.0.7*

I have had this succeed in vibrating twice. I even reset the watch in hopes it was something I could fix, then it worked twice and stopped again. I have missed doctor appointments and woke up late for work. Waste of three dollars.

### 1/5 — Hätte gern mein Kleingeld zurück

*2024-01-05*

Günstige App. Billige Leistungen. Schafft es nicht zu erkennen, wenn die App die Health Zugriffe hat die sie braucht. Absolut keine Empfehlung. Wenn jemand ne gute Alternative für iOS hat immer her damit. Bis dahin nutze ich den default Wecker.a

### 1/5 — Trash

*2021-09-30, version 2.0.7*

I don’t recommended , don’t work appropriately

### 1/5 — Does NOT work

*2021-08-06, version 2.0.7*

I downloaded this app hoping it would help but it won’t even let me set an alarm at all!!!  Do not download it is not worth it.

### 1/5 — Doesn’t work

*2021-02-16, version 2.0.7*

For the last few times this app failed me terribly. Either it consistently woke me up exactly 30min before the scheduled time regardless of my sleep stage, or it failed to sound even at the scheduled time itself. DO NOT WASTE YOUR MONEY on this!

### 1/5 — Will not work

*2021-01-21*

I have a series 6 watch, and this will not work properly. For each setting of the alarm thus far, I’ve been woken up within the first minute of the wake period, often being startled out of a dream. This morning, I was awake during my wake period, and the alarm did not go off. 

Series 6 should offer precise wake times for this app. I have had no success and am utterly disappointed.

### 5/5 — Perfekt für Apple Watch

*2021-01-20*

Ein perfekter Wecker für Apple Watch. Benötigt keine Verbindung zum iPhone in der Nacht und spart somit Akku. Weckt tatsächlich zum besten Zeitpunkt. Bin sehr zufrieden, kann auf jeden Fall weiterempfehlen, 5/5 Sterne 👍
