About this app
Hey kids, parents, and educators! Have you ever tried to learn to play any musical instrument but got lost after getting introduced to reading music? Now, this is over! With this fun app, you will learn the basics of reading music - drumming and drum notation, while playing a rhythm tap game.
In this adventure, you get introduced to the crazy and happy music notes named Rhythmiacs, who live in a village full of rhythmic challenges!
You will improve your reading and rhythm skills step-by-step by tapping on a virtual percussion instrument or by making your high scores with real-time feedback! Turn on the microphone in the app and improve your rhythm skills with a real instrument - a drum, tambourine, or drumsticks. You can even clap along!
No need to hang in front of your screen for hours! We recommend playing with the worldwide awarded app for 10-15 minutes weekly.…

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
Under 65% 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.

Method and limits
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.
