FAQ
Questions, answered
What is a “clean tempo”?
The fastest tempo where your timing is still consistent enough to build good habits. one&a finds it, tracks it and helps you raise it.
When does one&a tell me to speed up?
When your recent takes show stable timing at the current tempo. If accuracy falls apart after a jump, it steps you back.
Do I need a drum kit?
Is the beta really free?
Yes — every feature, no card required. Early users get a founder discount when subscriptions launch.
