Photo Trap Change Detection 4+

Decent app but I think it relies a lot on the user, which is fine. What’s the ultimate difference from following the instructions and doing them with your built in photo app? I think if the phones LiDAR was introduced you could get 3D images of the foreground which would help spot movement.

This is such an easy and intuitive app to use. Zooming in on the image and tapping to switch shows you if something is even slightly misaligned. Obviously it's easier to tell if you can align both of the shots perfectly, but even if they're slightly misaligned it's still easy to spot the differences.

One suggestion to improve the app- display a 3D accelerometer arrow in the corner of the image so when you take your second picture you can first re-align the 3D arrow with the ghost arrow. That way you know your angle is correct and you then only have to move the camera in two dimensions to align it.

This is an amazing app! I have multiple little brothers and it is quite hard to know if my stuff has been messed with, but this app will change that. It works amazingly. The only issue I can find is that it is quite difficult to make sure you are lining it up right. The fix for this is to include in the picture an unmovable object like a window, heavy desk, a stain on your desk, etc. Other than that little quirk this app is worth it.
