Oh Appy Day! gives you the scoop on the coolest apps from some of the coolest people anywhere. This week, Dr. Harvey Karp shares his fave.

Besides helping parents have more fun with their babies and toddlers, I have spent the past 20 years working to make our environment safer for kids. That’s why I love Al Gore’s app. The Our Choice app is beautiful, fun and intelligent (the perfect date!). It leads us on an exciting exploration of the important environmental issues we all face over the next 10 years….and that will re-sculpt our Earth–for better or for worse. – Dr. Karp

We (like all parents!) are huge fans of Dr. Harvey Karp, author of The Happiest Baby on the Block and the newly released The Happiest Toddler DVD based on the book. It does for kids 8 months to 5 years what the original book does for babies. Follow him on Twitter @DrHarveyKarp
