Great, simple, and useful. I wanted a checklist that would function directly from the desktop background of my phone, and this works perfectly for that. Intuitive, easy, and reliable, and nothing more than what I want. Update:A year later & still no better task app for a Samsung. Updates only made this app better. Sublists are easy to organize. Setting controls very useful. I don't use it for reminders b/c it doesn't get my attention as well as my phone's alarm.
