What’s the catch? Aggressive ad load — reported by 36 users.
Analyzed automatically from 3 independent signals that had to agree — not a hands-on test, and not human-reviewed.
This analysis describes version 4.1.2 of the app, analyzed 2026-10-04 . The app may have changed since.
The store currently lists version 4.1.3, updated 2026-10-01.
The app has been updated since this analysis. The findings on this page describe version 4.1.2, not the version now listed on the store.
Release notes for the newer versions, in the developer’s own words:
Version 4.1.3 · 2026-10-01
- Less intrusive opening ad: fewer interruptions when returning to the app - Rewarded ads now preload for a smoother, faster experience - Improved crash reporting to help us fix issues faster - Fixed several chord name translations
What the analysis found
The catch list 1
Charges we publish at a strength we stand behind: measured from an artefact, agreed by independent sources, or reported by enough users to clear that charge's own published bar.
Context 1
Measured and published because a reader would want to know — deliberately not a charge. The measurement alone does not show a harm.
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.
What reviewers said
Verbatim excerpts from public store reviews, shown as corroborating user reports. They are not Appworthy audit evidence, and a quotation is not proof of the finding it sits under.
Aggressive ad load
One of the worst tuners out there! — This app doesn’t even respond to inputs. The needle appears frozen to one spot most of the time. I wouldn’t recommend this app for free users. For free users they will also make you watch a 30sec or…
Ads — Makes me watch an ad or pay just to tune
To many ads — When I log in there are ads to use the app
Paywall blocks the basics
Horrible tuning — Reads another note during tuning and makes me struggle more than I should to tune my three guitars. Also everything is locked behind payments and ads. 1 star never using this damn app again.
Used to be good — This app stinks now because before it was free and now you have to pay for everything and watch a bunch of ads for now sub par quality
It used to work but... — It used to work but when I went on it just now it said "you don't have access to this" apparently now you have to pay to LITERALLY TUNE A GUITAR, like that is so STUPID
What this app sells
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
Show 3 more purchases we couldn’t categorise
These are really on sale; we just can’t tell from the name whether they recur.
How the automated analysis works
This assessment is produced automatically. Three independent signals are read — user reviews, the store listing and the store privacy disclosure — and each candidate finding is filed under the sources that support it.
No charge stands on one kind of evidence — with one published exception. A finding is either a measured fact that anyone can reproduce (an ad SDK is in the package; every subscription bills weekly; the privacy label omits a tracker we can see), or it is an interpretation — and an interpretation needs independent sources to agree before it reaches the catch list. The exception is a harm only users can see: a charge may publish from reviews alone, as “Reported by N users”, once enough reviewers raise it to clear that charge’s own published bar. That agreement rule is what replaced the human reviewer, not a model’s confidence.
There is no overall score, on purpose. A 0–99 number was published here until 2026-09-15. It was withdrawn because it discriminated too weakly to be the instrument — 44.7% of every pair of apps tied — and because a single number is a verdict where a count is an observation. What publishes instead is a row of measurements, each of which says what was counted and, where we could not look, says that instead.
Findings under One source only are real reports we do not stand behind as findings. They are shown because withholding them entirely would hide a genuine complaint, and labelled because publishing them as charges would be an accusation off a single source.
Several measurements above say “Not assessed” because no artefact we hold can answer them. A human review is what resolves those — and it can remove a favourable band as easily as add one.
Hands-on inspections are not yet open.
