Riffday

Riffday とは？

Riffday is an all-in-one practice companion for musicians — chromatic tuner, pro metronome, session timer, and a frictionless practice journal in one app. What's different: • 1-tap to start a session. No setup, no friction. • 3-field journal (good / improve / next). Blank saves are fine. • Heatmap & streaks make consistency visible. • 100% offline. No accounts. No servers. SQLite on-device — your data stays yours.
