Ola Kids

A handwriting app that teaches children English and Sinhala letters by tracing them. It works with no internet, no ads and no accounts.

Where it is now
The Android client test build is ready, and the app is being prepared for Google Play and the App Store.

01

The challenge

Young children need to learn letters and numbers before they can read instructions. So the app had to guide small hands with pictures, sound and encouragement.

It also had to teach both English and Sinhala, run on everyday phones, and keep every child's data on the device.

02

What we built

  • Tracing for English A to Z, Sinhala letters and numbers 1 to 9
  • Animated guides that show where to start and which way to go
  • A trace checker that confirms a child stayed on the letter, covered enough of it and skipped nothing
  • OlaSauras, a mascot who speaks English and Sinhala with on-screen captions
  • Separate profiles and saved progress for several children on one phone
  • Stars and gentle encouragement instead of scolding
  • Support for reduced motion, larger text and screen readers
  • The Trace the O brand identity, app icons and animated launch screen
