This is an interesting concept. I bought it because I always wanted a counter/goal app. I have some feedback right away.
The convention is to edit a list, tap and hold on the goal and then you can drag it around. I like that youre trying the shake concept, but for the sake of the user who has to re-learn everything specific to each app, I encourage consistency. Id expect to be able to rearrange it the conventional way by just tapping, holding my finger on the screen, and then being able to rearrange the goals.
Also, I intuitively swipe right to count down. But that seems arbitrary. Really Id like to see the tap/hold feature implemented so Im not confused switching between apps.
