### 5/5 — Battery Watcher

I just absolutely love the Battery Watcher that I can look to see how much percentage of my battery I have…there’s no wondering how much or how low my battery is…it pretty much assures you your battery will not ever run dry…..Thank You BATTERY WATCHER!

### 2/5 — Nicht gut

*2025-01-15, version 1.4.9*

Zeigt phantasiewerte an.

### 5/5 — Sehr gute Unterstützung

*2024-10-25, version 1.4.9*

Sehr zum empfehlen

### 1/5 — App ist tot

*2024-09-21, version 1.4.9*

Auf Stand von iOS 14. Seit 3 Jahren keine Weiterentwicklung mehr, die App ist tot. Premium gibt es schon gar nicht mehr.

### 4/5 — Gut, aber nicht sehr gut

*2024-09-03, version 1.4.9*

Sinnvolle Funktion. 
Die Anzeige erfolgt aber nur in 5%-Schritten. Das finde ich zu ungenau, da die Daten ja vorhanden aber nicht komplex ausgewertet werden. 
Da ich zu den sogenannten 80%-Ladern gehöre, um den Akku zu schonen, wäre mir eine detaillierte Anzeige und am besten noch ein Signalton bei genau 80% Ladekapazität wichtig.

### 1/5 — Not low battery

*2024-07-17, version 1.4.9*

I don’t like it because u can’t do a low battery mode

### 5/5 — Noreen Chase

*2024-07-08, version 1.4.9*

This works perfectly.  It keeps me aware, but doesn’t interfere with my day.

### 5/5 — Very good and informative app

*2024-02-02, version 1.4.9*

Very good and informative app…..

### 1/5 — Zeigt falsche Werte an.

*2023-11-04, version 1.4.9*

Die App zeigt dauerhaft falsche Wert an. Aktualisiert sich nicht.
