OFFBEAT is a rhythm training app built for ska punk and jazz musicians. ■ Train the "gap" a metronome can't teach you Just tapping along with a metronome doesn't build the feel you need on stage. OFFBEAT focuses on the genre-specific placement of rhythm — offbeats only, the third note of the swing triplet, the 2 & 4 backbeat — and visualizes your timing error in milliseconds. ■ 6 specialized training modes - Offbeat Master (free) — the 8th-note offbeat that underpins ska cutting - Swing Pocket (free) — the "third triplet" feel of jazz time - 2 & 4 Backbeat — the shared backbone of jazz and ska - Silent Keep — hold your internal groove through bars of silence - Tempo Sprint — survive accelerating tempos without rushing - Call & Response — hear a phrase, play it back ■ Output latency calibration Measures the output delay of your earphones/speaker and folds it into the judgment, resolving the feeling of being "off" when you're actually on time. That said, since Bluetooth latency itself fluctuates, please use wired earphones or a speaker. ■ Built to keep you coming back - Three 30-day lesson courses (All-round / Ska focus / Jazz focus) - Day-streak tracking with a weekly one-day protection freeze - Timing diagnosis after every session: are you rushing or dragging? - Score, accuracy and average offset recorded every run [Pricing] - The app is free to download. - "Offbeat Master" and "Swing Pocket" are free forever, with no time limit. - A single purchase unlocks the other four modes (2&4 Backbeat, Silent Keep, Tempo Sprint, Call & Response) and all three 30-day lesson courses (All-round, Ska, Jazz). - This is a one-time purchase, not a subscription. Once you buy it, the content listed above is yours to keep. - After reinstalling or switching devices, use "Restore Purchase" in Settings. ■ Privacy All play data stays on your device. Nothing is transmitted (see the privacy policy for details). For you if: - You play in (or want to join) a ska punk or jazz band - You can follow a metronome but can't sit in the groove - You've ever been told you rush on the offbeats — From the developer I've played in a ska punk band and spent years touring the jazz cafés of Japan, yet I never trusted my own sense of rhythm. Metronomes and method books didn't fix it. "It isn't talent — there has to be a way to train this." So I built it with the one skill I did have: programming. That's how OFFBEAT began. Not for people who already have rhythm, but for those who struggle, like I did. Starting with ska and jazz — and someday, for every player, in every genre. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Unlock 6 modes + 3 courses | $5.99 | one-time | ## Version history (last 4 releases) ### 1.3 — 2026-08-02 ■ Purchase improvements ・Fixed "Restore purchase" reporting that no purchase was found when it simply could not reach the store.
