How it scored
Every dimension is scored against this discipline’s published rubric. Open one to see the claim it was scored on, what the rubric measures there and how much it weighs, and where the evidence came from.
How we scored this
We read the agency’s public record first-hand — its site, pricing, case studies and independent reviews — and score what is checkable: what is published, not how it is phrased. There is no keyword counting or sentiment scoring. The label is a judgment on those facts, which is why each dimension shows the fact that decided it, the band it was judged against, and the sources — so you can check the call, and tell us if you think it is wrong. The full method, and who pays, is on how we vet.

Verdict
App Guardians clears the bar because it optimizes beyond install volume. Its LiveWell case describes shifting campaigns toward enrollment events and reducing CPA while scaling budget, and its service model connects ASO with cross-device engagement and retention.
Measurement and creative-testing evidence are credible but less detailed than at the leaders. Define the activation event, retention window, MMP, and incrementality test before launch.

Red flags
