About this analysis
ZCAnalyzed by Zakhar Chumak · founder, bumetric·Full methodology·Low confidence

Why low confidence: only 20 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.

📌 Final verdict — read this before you trust the numbers above

Herzfrequenz Plus PRO is a small / niche iOS app in the health & fitness space with weak public traction — only 20 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.
