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
Studio Mosaic is a strong fit for app teams that need ASO and full-funnel growth support from a specialist. Clutch lists 59 reviews and a current 2025 engagement reporting top-10 keyword growth from 32 to 172, iOS organic installs rising from roughly 50% to nearly 70%, and more than tripled impression-to-install conversion. One negative review is openly acknowledged; buyers should examine it and contract for attribution, MMP, fraud, account access, and data ownership.

What other platforms say
Large specialist review set supports ASO and growth delivery; one negative engagement and thin privacy/fraud detail require diligence.
These are other platforms' numbers, not ours. We report them because they are part of the picture, and we do not average them into our score — our score comes from the published rubric above.
Red flags
- At least one negative Clutch engagement exists
- Modern privacy and fraud controls are not public
- Require post-install cohort and payer-quality reporting
What we could not verify
- SKAN, ATT, MMP, and privacy practices
- Fraud rejection and account-permission controls
- Standard pricing, termination, and data ownership
