Belajar Menulis (Learn to Write) is an Android app that is perfect for children learning to write (and read). It comes with a collection of Indonesian children's songs, making it a great companion for kids. The app is unique in that it has many cartoon illustrations for every letter and number, which are both fun and engaging. It also has sound, which can be changed to a recording of your own voice (e.g., Mama, Papa, or older sibling), making it more interesting for children to learn to write and read. The illustrations can also be changed, making the learning process even more enjoyable. The app is small in size, easy to use, and suitable for all smartphones.
