- 💰 Revenue: Modest — $787 - $4921/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.1★ across 23 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: last update 188d ago — slow cadence.
- ⚠️ Risk: Low — no material risk signals detected.
🎯 For competitors: Mixed picture. Worth competing if you have a clear UX or pricing edge — otherwise crowded segment.
💵 For acquirers: Estimated asking range 18-32× monthly = $35K-$62K. Portfolio play ($18K/mo combined) commands premium.

About this analysis
Why low confidence: only 23 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.
📌 Final verdict — read this before you trust the numbers above
Cardio Zonen is a small / niche iOS app in the health & fitness space with weak public traction — only 23 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.
