Keeps crashing and other issues – iRewardChart: Chore Tracker Review

Latest version keeps crashing. Issues with login and auth errors. Aside from latest version, I can't back date a reward entry. I can't give a reward to my son and allow points to go negative. Response to another reviewer, you just hold the star to subtract it if you accidentally add one. Many of the screens aren't real intuitive and you have to stumble through how to use them. It also feels like the person that coded the points portion is different than the person who recorded the rewards area. They are completely different and it is like learning two different apps.
