Release notes for the newer versions, in the developer’s own words:
Version 3.27.1 · 2026-10-02
There's never been a better time to start playing, and with these latest app updates, your guitar journey is about to get even more exciting! - The tuner has been updated with improved tech, and is now faster and more accurate. - Typing interactions have been redesigned, and copy, paste, drag and autofill all work better. - Karaoke's count-in now shows the lyrics and chords coming up, so you have a moment to get ready. - Your profile menu is easier to tap and opens instantly, without waiting on anything to load. - Many small bug fixes were made. Like a well-rehearsed orchestra, we've also made a number of subtle improvements and fine-tunings behind the scenes to keep everything running…

What we measured
Each line is a measurement published as a measurement, never a verdict.
Each line is a measurement, published as a measurement. Where we have not looked, the line says so rather than reading as a zero.

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
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 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 about the app, not a finding about it.

What the analysis found
App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.
Positive evidence 1
Things this app does right, published at the same strengths as the catch list.
Developer says data deletion can be requested
The developer's data-safety disclosure on the store states that users can request deletion of their data, or the app's own text offers a way to delete the account. This restates what the developer declares; it is not a test of whether deletion works. Apple publishes no equivalent disclosure, so on an Apple-only listing only the app's own text can support it.
What we saw: The developer's store data-safety disclosure states that data deletion can be requested; we have not seen a deletion control in the app's own text
One source only — shown, not confirmed 1
A single kind of evidence. We publish these because withholding them would be the bigger distortion, and we do not treat any of them as a finding we stand behind.
From the store listing: Usable without an account
The app's own screens offer a way past sign-up — guest access, skipping, or browsing before registering — rather than gating the product behind an account. The store's privacy disclosure is checked alongside it: that disclosure is self-reported, so it corroborates this credit rather than establishing it.
What we saw: The store privacy disclosure (5 entries) links no contact details or identifiers to the user — consistent with an app that does not require an account. Self-reported by the developer.
