💡 A powerful type of intelligence: synesthesia.
📚 The main purpose of this app is to hear digits's music.
🎯 It's more than a training, you'll see and hear, at the same time, every digit.
🎯 You can choose the right instrument sound for your own delight. There is a C key scale from C to B (without halftones).
🎯 Also, for your fun, you can play on those instruments by using the main (black) frame (click on margins for fullscreen).
🔔 This app is a pilot project and must be treated as such...
