5 Reward Chart Apps

I have just read the article on 5 Reward Chart Apps.
I have an ipad and the kids use it. We have started using an app named Cheerful charts. The paid version ($1.29) is fun and works really well. you can customise each row and name the chart.
Worth a download fellow ipad users. My boys (4 & 6) open the app, tap on their icon for their chart, then tape the row for the reward. A cute picture turns into another icon and makes a noise. They love it. When you get 5 in a row there is a big well done and clapping.
Hands down my favourite Reward Chart App.
