Evidence and review signals
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.
What we measured

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
90% or more 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.

“Why am I still getting ads on the pro version? Can you please remove these ads. It is not registering as a pro version after I upgraded. The ad version is still on my phone home screen when I launch the app. But when I go to the no ads…”
“I have been a fan of this app before they came out with the paid version! This app has come in clutch for me for years when leveling my trailer, which is just as accurate as an actual bubble level. I've used this to hang TVs and pictures…”
