SUS4 Time Trainer: Rhythm
Score how tight your timing is
Free · In-App Purchases
Told you rush the chorus. A few minutes on the pad with the click shows by how much, and the session history shows whether it is getting better.
Locking to the click is a skill. Here is how you build it.
A rhythm trainer that scores your timing against a click, pass by pass.
See in milliseconds whether you are early or late, then drill with the click muted.
Playing in time sounds obvious until you sit down with a metronome and really listen. SUS4 Time Trainer gives you a structured way to improve: play to a click, and the app tells you how well you are landing. Too early, too late, or right on — you see the data after each pass.
Mute-click mode is where the real practice happens. The click disappears and you have to maintain the pulse internally, then the click comes back to confirm whether you held it. Drift tracking shows you if you are consistently rushing or dragging so you can correct the habit, not just the individual note.
• Play-to-click accuracy detection via mic
• Acceptance-window display — see how close each hit lands
• Mute-click mode for internal pulse development
• Drift tracking — identifies rushing or dragging patterns over time
• 3 sessions free per day — subscribe monthly or unlock once for life for unlimited access
All detection runs on-device. No audio stored.
