Same premise as WeReward and Shopkick. What could be the problem??....
With WeReward I haven't amassed millions yet but throw a few pennies on the account/day. It's a "whenever I remember about it" kind of App for me.
Shopkick I check off my stores every morning and have enough kickbucks to purchase the second gift certificate.
With Checkpoints however, the reward points accumulation takes too long.
I'll keep the App but doubt I will make much use of it.
