Hey Product Hunt! 👋 I'm Sung Hwa, a frontend developer who's been playing guitar (badly) for years. The problem I kept hitting: my tuner, metronome, and practice notes all lived in different apps — and the journal one always felt like homework. So I'd skip it. Then I'd forget what I worked on yesterday. Riffday is the app I wished existed: → 1 tap to start a session. Tuner and metronome are tools, but the journal is the heart. → The journal is just 3 fields (what went well / what to improve / what's next) + a condition LED. Blank saves are fine. Zero pressure. → A heatmap + streak make consistency visible — the thing that actually got me practicing daily. → 100% offline. No accounts. No servers. SQLite on-device. Your practice belongs to you. → During tuning, metronome, or an active session — zero ads. Tools shouldn't interrupt practice. Free with optional rewarded-ad unlocks (recording, weekly report sharing) and a one-time IAP to remove ads. Currently Android only — iOS coming next. I'd love feedback from fellow players: what's missing from your practice routine? — Sung Hwa
