About this app

Every guitar/bass player knows that they *should* have the fretboard memorized, but they don't because it's tedious and boring. Fret Pro can do all the hard work for you! With just 10 minutes a day, you’ll have the fretboard memorized in no time. It's easy and fun!

SPEAK THE LANGUAGE OF YOUR INSTRUMENT

Having the notes on your guitar or bass fretboard memorized is the most important step toward becoming fluent in the language of your instrument. When you master the fretboard, you can spend less time thinking and more time enjoying playing music.

PLAYER HIGHLIGHTS

- "I’ve had lessons on-and-off for 10 years, but never did the work of really knowing the notes on the fretboard. I didn’t think it really mattered. But now, concepts I slightly understood before are falling into place, and I’m able to communicate with my teacher in the same language.…

Five-star share of ratings
80–89% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the app package we scanned

No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

This list is cut off. Apple shows at most 10 in-app purchases, and this app is at the limit — so it very likely sells more than we can see.

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
