Its a nice enough app but it doesn't have the main thing I was looking for, which is to be able to free-draw on a photo with a tool that allows different settings of line color, width, and transparency. Yup, checked, its not there. Spend as much time fixing your app as you do writing patronizing responses next time. Now its one star.

New user:Just wasted hour&half. Started out easily enough, but hit a snag w/ 2nd text box.. couldnt get it placed, straightened or sized at once Initial & constant issue: box points not collaborating w/ dir. & app insisting on creating multiple boxes & wherever. I swear, it seemed to resist at every request! Finally, I snapped out of this twilight zone & tried another app also for 1st time. After ditching your bratty-app, it was smooth sailing for me. Done in mins w/ exactly what I had in mind.
