Great App - no longer working..
If you spend some extra 5-10 mintues figuring out how you want to use this app you will be greatly rewarded. I have been using it many times daily for four years on both iPhone 4 and iPhone 5. However the app does not function any longer (with iPhone 6 and iOS 8) so I am now using another checklist app. This is OK but only second best. I really miss the ability to configure your own categories within each list and will switch back to Checklists right away if an iOS 8 compatible upgrade becomes available.
