## What is SUS4 Time Trainer?

Locking to the click is a skill. Here is how you build it.

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.
