Want your child to learn to finally clean up after herself, stop pushing people, or sit down in class? There’s an app for that. Seriously.

A Culver City, Calif., dad, Kevin Spiteri, created the Behavior World app, a positive-reinforcement tool for parents, teachers, and kids,released July 22 — with his Helping Hand Systems business partner, Bryan Saavedra — as a way to help Kevin’s son, Kyle, now 9, who was having a difficult time after Kevin split with Kyle’s mom in 2010.

“The divorce was very tough, on all of us,” Kevin tells Yahoo Parenting. “Kyle started struggling with his behavior in preschool. He was always a superactive kid, but he began doing things like pulling hair and not listening at all, and he kept being sent home.” As occupational therapists who work with children with and without special needs, Kevin and Saavedra (also a dad) know a thing or two about helping kids. But easing this difficult family transition for the boy was proving tough.

“I went as far as paying someone to be with him during the day at school, to make it through the day and not be disruptive to the class,” Kevin says. “I was willing to do anything to help him.”

When Kyle got to kindergarten, Kevin says his boy continued to act out. “There was a period of time when I tried everything to get his behavior under control,” says the single father. “I took away things. I punished him. I was desperate to try to help him gain control over his behavior, and nothing was working. It wasn’t until I used positive reinforcement that I started seeing a lasting change.”

The most effective way that Kevin says he helped his son adjust his attitude was through a Candy Land-style game he came up with one day, jotted out on a poster with colored squares and the promise of a reward after progressing 10 spots on the chart documenting good behavior. “Kyle wanted this toy that shoots marshmallows,” says Kevin. “So I took a picture of him with it in the store, put that photo at the end of the chart, and worked with his teacher to put a happy-face sticker on his school sheet when he kept his hands to himself and listened well, which advanced him on the board.” It worked, and Kyle got his toy.
