Avril Lethbridge, a grandmother from Oxford, UK, has created an app for iOS devices to help parents reward good behavior. Based on a card game she invented two years ago, Nice Bear Naughty Bear uses a cast of cartoon bears like "Tidy Bear," "Yelling Bear," "Greedy Bear," and "Thank-You Bear" to teach good and bad behavior to kids, with the additional help of rhyming couplets. Parents can add their own characters to accommodate particular positive and negative traits, and the app offers goal-tracking and reward features.

The 74-year-old Summertown resident was inspired to create the system when she had to give up her seat on a bus to an older woman after the surrounding teenagers didn't consider moving. She told the Oxford Mail when she launched the original cards that she believed that, "teaching a child to say please and thank you gives them a better start in life. People will always remember someone with good manners." A lite version of the app is available for free, but the full version supports more than one child, unlimited rewards, and will speak the rhymes to you for $2.99 / £1.99.
