I tried out several to do apps to replace my sun-setting Wunderlist and liked this one the best. The only feature I'm missing at this point (and it is a big one, thus the 4 instead of 5 stars) is a list of all tasks/to dos. One master list of everything from all other lists is a crucial feature and very much needed! For now I am marking all tasks as important so they are all captured there as a workaround. P.s. I am loving the tags feature, and the audio when you check a task off. So fulfilling!
