- 📈 Growth: ⚠ last update 1776d ago — possibly dormant.
- ⚠️ Risk: Elevated — dormant (1776d since update).
🎯 For competitors: Vulnerable. Quality drift + slow updates create a clear opening for a fresh competitor with active dev cadence.
💵 For acquirers: Estimated asking range 18-32× monthly = $39K-$70K. Portfolio play ($12K/mo combined) commands premium.

About this analysis
Why low confidence: only 28 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.
📌 Final verdict — read this before you trust the numbers above
Coaster-Count is a small / niche iOS app in the travel space with weak public traction — only 28 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.
