Five-star share of ratings
65–79% 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.

Store update history

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.

App Store

Version 3.0.1 · 2026-10-10
NEW SECTION: PROGRESS Vox Tools now keeps track of your practice. In the new Progress screen you'll see how much you've practiced, your streak of consecutive days and the notes, scales, routines and songs you work on the most. When you finish a routine or a song you'll see a short summary and, once a day when you open the app, a summary of your week. If you like, you can help us by sharing your practice statistics anonymously. It's completely optional. SONGS Now, right before each line of the lyrics, a green bar tells you when to come in and start singing. If you'd rather not see it, you can turn it off in the settings. We've also added buttons to go back and forward 5 seconds.…

Shortened here; the full notes are on the store listing.

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.
