I needed an app that would allow me to show the exact time from the phone's clock in front of a camera used to shoot legal depositions. I also wanted it to allow me to display the case number, witness name, date, and attorney names. I can do all of that on the phone app. Granted, I can't change the names of the fields (eg director, scene etc.) the iPad version allows a little bit more text to be displayed.
I don't really need the clapper/audio feature, but I did some test shots. It seems the red dot displays a couple of frames before the sound is heard on my camera, so be aware of that if you're using it to sync audio.
Also, the last numbers near the time--the frames number-- is completely random. It goes up to 20 something several times per second, when it should go from 0-30 only once per second. Not a big deal though. I don't use that number for anything anyway.
