About this analysis
Why low confidence: only 27 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.

Muscular System 3D (anatomy) is a small / niche iOS app in the education space with weak public traction — only 27 ratings, no founder-verified MRR, and not ranked in any monitored grossing chart. The app appears to be monetised, but public signals are too sparse for a precise revenue estimate.
Bottom line: treat all revenue, audience and acquisition-value numbers on this page as directional only — not founder-verified facts.
