This had been a must have app for timed psychoeducational assessments. The most recent update (1.10), however, has been frustrating. It initially crashed each time I tried to change the time limits. Reinstalling the app and making only one change then exiting worked. The current version does not disable the dim and lock screens on my iPhone 4, making it difficult to time some tests without touching the screen. These need to be fixed before I can go back and give it a 5-star rating again.
