See, I have used Prey for a number of years on all my companys laptops and my home one. It works great. From my web control panel I can manage it easy. From the protected device there arent any options except to log in, so I think some users are missing that they need the Prey Control Panel on the website. Also, if its on a iPad with a password, unless a thief somehow unlocks it and hooks it up to wifi, it will never help you recover it. For phones the same. If a thief cant get into an iPhone they turn it off. Advice for any tracking app on an iPhone:
Dont password protect your iPhone. Instead activate restrictions in settings so that some features like phone & games (or just games) can be used but no apps altered, deleted or added, no account changes, no reset, restricted with a password instead. This way, if your phone is ganked...
That will encourage the thief to keep the phone and use it and connect it to wifi or use the cellular data (allow changes to wifi). With the Prey app running on your phone you can disguise it as a shooter game you need to log in to, so if its noticed itll just be passed over. All the time he thief uses your phone the phone is taking his/her photo and sending it to you over the wifi along with gps location and other info.
Not as smoothly as Prey works on computers, since you have to take so many darn steps to make it work but once its set up it WILL and DOES work to recover your phone.
None of this info is very clear on the app and had I not known beforehand about Prey I would have trashed the app as useless garbage with no features, too. Look up Project Prey Control Panel on the web and set up your account there first, THEN log into the app your iPhone/iPad/iPod and go from there. Theres a user forum that can help answer questions as well.
