How much does FDNY make per month?

Based on our ML-calibrated revenue forecast, FDNY earns approximately $2.7K/mo. This is a US-storefront-equivalent estimate; global revenue can be several times larger for internationally-distributed apps. See the methodology page for the full formula and confidence bands.

With estimated build cost $160K and monthly revenue $2.7K, FDNY looks slow ROI — payback period is around 4.9 years at the current run-rate. Profitability also depends on paid-acquisition spend and refund rate which the public model doesn't see.

💰 Revenue: Modest — $1K - $6K/mo · INDIE tier · medium confidence, trajectory unclear.
⭐ Quality: 3.2★ across 82 reviews — weak — significant quality concerns.
📍 Market: Not yet charting in any of the 9 monitored markets.
📈 Growth: ⚠ last update 1191d ago — possibly dormant.
⚠️ Risk: Elevated — dormant (1191d 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 = $49K-$87K. Portfolio play ($63K/mo combined) commands premium.
