This app is one of the best produced children apps I have seen so far. Bugs and Buttons is impressive both visually and musically, and is presented in a very child friendly way. Bugs and Buttons includes 18 mini games that promote learning skills such as counting, colours, fine motor skills, path finding, patterning, sorting, tracking, letter recognition, and sequencing. Each game is well presented and easy for children to get into each game. The levels increase in difficulty as you progress, but if something is proving too difficult it will put you back a level, so that you can start to experience success again before having another go. There are stamps to collect along the way as you complete levels and activities. Bugs and Buttons currently is $2.99 from the app store. A very worthwhile purchase. Please find below a video demonstration of Bugs and Buttons from the DailyAppShow.
