This is hands down the best personal planning app I've ever come across. That being said, it's basically unusable on Android. The view jumps to the top of the day's task list at random, making it easy to accidentally check off the wrong task. It takes minutes to load anything when you try to access the rest of the app through the back arrow at the top left. And, on occasion, tasks will duplicate themselves multiple times with different parameters. I use it on my iPad with no trouble at all.
