### 5/5 — Works great

*2025-12-14, version 1.6.4*

Good for naps at work

### 1/5 — Undulations like on a boat

*2025-11-19*

The preview undulates like waves in the ocean. Using the back camera. Motion detection always triggers immediately. The video captured is also undulating. Turning off autofocus has no effect. I checked and if I shoot a video on this device using Apples native camera app it is perfect. Please help, and I will revise this rating.

### 5/5 — Very good, small remark

*2024-09-30*

Excellent apps! I just cannot find the « power save » option button on the Motion Sensor app, I have it on the Cambush app. 
It is mentioned in the « new features » list though?
Thank you!

### 3/5 — Zoom

*2024-07-11*

Cannot set camera zoom, I hope this feature in th next upgrade

### 5/5 — Doesn’t work

*2024-06-27*

I’m calling Apple I want my money back because it DOES NOT WORK!

### 1/5 — Not ideal for surveillance as advertised

*2024-06-24*

When using the front facing camera, there’s no way I found to hide the screen when it’s recording. Minimizing the app or opening another app to hide the screen stop the recording. This makes it obvious to everyone that the camera is on and recording. It also wastes battery life. I’d like my $5 back please.

### 1/5 — Sad

*2024-04-06, version 1.6.4*

Your app doesn’t work from block screen and someone breaks into the phone first car nap.

### 3/5 — Eigentlich sehr gut, aber zu oft Abstürze

*2023-06-25*

Sehr gute Einstellmöglichkeiten, empfindliche  Detektion - eigentlich eine super App wenn sie nicht dauernd abstürzen würde. Schade, dass sie anscheinend keine Updates mehr erhält und mit aktuellem iOS Probleme hat.

### 1/5 — Instabil

*2023-03-31*

Gute Idee, viele Optionen einstellbar. Aber was helfen die besten Optionen, wenn die App ständig abschmiert? Entweder zeichnet sie einfach nur nicht mehr auf, oder aber sie lässt sich erst gar nicht mehr starten (hier hilft nur iPhone Neustart). 
Der Sync ins Fotoalbum funktioniert auch nur sporadisch, ebenso in die iCloud. Irgendwann bricht der Sync ohne Meldung ab, dann wird auch nichts mehr aufgenommen. 
Sehr schade. Leider eine Fehlinvestition.

### 1/5 — Freezes - find another solution

*2023-02-02*

I cannot get this app to work without it freezing.
