About this app

SunABC helps learners master letters and syllables with e.g. a simple, touchless loop: watch, listen, and repeat. The app uses smart repetition to balance variety and mastery, tracks progress automatically, and includes gentle animations and pacing controls.

Features:
- Touchless practice: no taps needed to progress
- Smart repetition with learning focus slider (variety to mastery)
- Multiple languages included, with additional languages available with Premium
- Thousands of syllables across supported languages
- Simple trends and progress dashboard
- Adjustable pace and animation intensity

Privacy-friendly: all learning progress data is stored locally on your device. We do not create user accounts, and we do not collect, share, or sell any personal or sensitive user data. Anonymous usage analytics are collected for users over 13 years old to help improve the app.

Note: Microphone/camera permissions enable richer feedback; if denied, the app still works in playback-only mode.
