I bought this app for my grandkids and they absolutely love it. It’s different- they enjoyed the show theme and were surprised about the funny “commercials”. They are repeating what some of the characters say about cleaning up and being respectful, and that’s why I got it for them. Great work; I bought the CD also. We all enjoy!

Great learning app for children!

Stumbled upon this app and now both my kids love Sir Dapp! My son particularly loves Duffie! It’s a great game to help teach my kids manners while keeping them engaged! The music that goes along with the app is actually really catchy. I find myself singing along with the kids! Downloading the album too!

Wonderful and much needed App!!!

As a psychologist and mother of two, I am always looking for new venues to reinforce manners and good values. This app is a wonderful asset to keep children engaged as they interact and learn to be polite and kind. Its simple design is easy to navigate for the little ones while remaining fun and informative.
