Does what it says on the tin. Needs an annual subscription OR you need to get a lifetime membership for free by submitting a new or changed camera.
Well worth the app price and the annual subscription!

I have been using this for over a year now and find it to be spot on. Having just changed phones I emailed CamerAlert in the evening to change my details and the following morning it had been done. An excellent product with excellent back up.
