It constantly crashes and misses a lot of functionality. Hard to use and annoys with some popups that can be discarded only by closing app and then opening it again and permanent noticfaction that CAN'T be disabled. Payd 30 euro for this and used for month before it got so annoying that I started to look for another app. Fortunately I found one - Todoist. It's unbelievable how much better that is. Also there is version of todoist for PC, for your smart watch and even as browser extension which allows you to easily set a certain web page as task. And all these are synced.
