Motion Detector is a stand-alone surveillance tool for your iOS devices. Motion Detector automatically takes consecutive photos using the device's camera and performs sophisticated mathematics for motion detection. When motion is detected, Motion Detector can start automatic recording and/or Email notification, so you will have physical records of what has happened.

The app also supports sound detection using the device's microphone. The app will alert you when the microphone picks up a sound above a specified sound level.

If you have a paired Apple Watch, you can remotely view the motion detector camera from your watch. For example, you can set your iPhone in the living room, and remotely monitor and control motion detector from the bedroom.

Ratings and Reviews

Works well


It works well for me. You can export your videos to photos and delete them if you want. I personally don't think it's much good for security use because it won't record with the screen locked. However Iif you think that the dog keeps eating out the bin it would work well for that.

My only complaint is that the videos appear in landscape mode despite being recorded in portrait mode even when I export them to photos.



Really quite a pointless app. Surely the fundamental idea of this app is to have a sensor which detects movement and then takes camera footage/reports back via email, all in secret and without the knowledge of the person snooping? As it stands you are left with an app that has to be left open and would take a halfwit not to realise what us going on, as it is in permanent camera mode and clicking away throughout. In any event it doesn't save the camera footage an fails to detect emails account as easily as the iPhone does when first setting up an account.

Will fill your phone up with images!


Ok firstly: i fixed the iphone 4 crashing problem by re-booting the phone.

Secondly: As has already been pointed out, this app does not save it's photos to the iphone's photo album.

Thirdly: You cannot transfer photos off the phone.

Fourthly: There is no way to remove photos from the apps own internal storage. I can only presume that this app will gradually consume all storage space on the phone until you delete the app and re install it.

Apart from that the motion detection bit works rather well! Kind of pointless without the above features, though, wouldn't you say?

Add file management and this app is worth every penny. However, currently it's a completely useless waste of money!
