Nothing is on the public record against it: no FTC or state action, no FDA warning letter, no failing BBB grade. That is not an endorsement, and it is a different question from whether the ratings agree — they do not, by 0.7 of a point.

Why is Knownwell rated 4.1 on one site and 4.8 on another?

Because the two are counting different people. Trustpilot has it at 4.80 from 210 ratings and Apple App Store at 4.14 from 29. Reviews left by anyone who chooses to, plus reviews from customers the company invited. Both routes are self-selected, in opposite directions. Neither is fake. They answer different questions, and no page that quotes one of them says which.

Which Knownwell rating should I believe?

Whichever you can say what it measures. The largest count here is 210 on Trustpilot, which is a lot of people and still only measures what that site collects. A rating cannot tell you what a company was told to stop doing by a regulator, what its contract commits you to, or what it charges once the introductory month ends. Those are on this site with the source and the date.
