ABC for Toddlers

Long time ago I made a simple app to help my son learn the alphabet letters. It worked surprisingly well. I thought that the simplicity was the key - no distractions. Years later I decided to do this for other kids too. My intention with this app was primarily to make a distraction-free little game that would keep the kids focused on learning the letters. My own son tested a similar app as a very young child and managed to learn the letters very fast.
 The first version of the app was in Serbian. It was released three years ago as a free Android game, and without any advertising, it got over 10,000 installs and a five-star rating. 
 I decided to make this English version for iOS and Android. The app contains no ads and no in-app purchases, so nothing comes in the way of the toddlers' full attention to fun and learning. The app price is $1.99.
 I pencil-drew all the illustrations and recorded the voices with my wife. Initially I had made the app prototype in React Native, but it turned out the audio performance was poor so I decided to use Godot for the production version of the app.
