I study guitar as a hobby. When I practice, I often play a little ahead of the metronome click. I can see it when I record myself with GarageBand.

I have been trying to adjust, but can't seem to progress.

Is there a metronome app that would give me a strong visual clue when I am not exactly on the beat?

• Edit for clarification: I am looking for an app that will call me out in real-time, either visually or audibly, whenever I play offbeat.

Why am I bothering with this?

I have heard musicians talking about making the metronome sound disappear by playing at the exact right time. I also noticed some people frowning when I play a split second before the click. Is it worth improving that aspect? Is there a better way to do it?
