Themes reported by reviewers
3 or more themes 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
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 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.

Methodology

One source only — shown, not confirmed 3

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.

Trial converts to a charge
“Taking people’s money?! — When you try to click on it to do the free trial… you charge people anyways. I want to say so many bad words to express how I feel about you shady people. It’s going to rain on your head!!!”

Trial converts to a charge
“Charges for “free trial” — Stated I had 3 days for free trial but automatically charged $5.99. App seems mostly useless as well.”

Trial converts to a charge
“Sneaky Sales Tactics and Poor Customer Service — I wish I could give them zero stars! Like most companies, they offered a free trial to try out their product. I downloaded their product along with a few others to determine which app would…”
