This app does exactly what it's intended for, which is to display your UDID. Now if you actually believe this will get you points on imobster you have just been fooled. Most likely whoever told you this already has access to your account for sending them your UDID. So be smart and don't give out your UDID unless you really do trust that person. And for the people to come, READ THIS REVIEW! IT WON'T GIVE YOU POINTS ON IMOBSTERS OR ANYTHING ELSE SO DON'T TRY.


As a developer I've used this app for years as a handy tool to easily get UUIDs of devices to make testing apps before release easier. However, I recent had a UK user use this (I'm in the US) and it sent the wrong ID to me, which led to a few days of painful testing trying to find out why my ad hoc beta wouldn't install. The ID started with fffff, so be careful. I think I might switch to Test Flight to avoid this issue in the future.


My dev just asked me for my udid number. I have no idea what that is. But I looked on the app store and there it was. Took a second to download and it instantly showed me my udid without and confusion. Even copied it for me for email. No bloat, easy, and clear. Thank you! :)
