Im a serious customer. I have the 25 image a day yearly subscription (over $2k yewrly) and use the iPad Air 2. The design is superior to that of Thinkstock. When it works, it is marvelous. However, it is buggy, and sadly fails more often than it works. Too often it wont display one of my larger light boxes, or breaks in the middle of doing so. Sometimes it starts displaying only half the images under similar images. Too often it wont let me add an image to an existing light box. I am forced to find the same image on the computer. Major waste of time. If they just focused on squashing all bugs for a few releases, theyd have a true gem on their hands. The basic design is excellent. They just need to reinforce its bones. Thanks for listening.
