ÄrräTreeni is a free mobile application designed to support speech therapy for children at home. Developed in collaboration with Finnish speech therapists, the app follows effective speech therapy methods to practice the pronunciation of the R sound.

The app is suitable for children of all ages, from 3 years old to teenagers. However, it is recommended that an adult uses the app alongside the child to provide support and spend quality time together while learning.

The app's structure includes the identification of the R sound, motor skill exercises for the tongue and mouth, and the pronunciation of the D sound. It also includes exercises for the small R sound, finding the vibration, and eventually placing the R sound in speech.

ÄrräTreeni offers various interactive exercises and games to practice and improve pronunciation. The app is available for download for Android devices from the app store.
