- 💰 Revenue: Modest — $3K - $7K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.0★ across 1 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: ⚠ last update 944d ago — possibly dormant.
- ⚠️ Risk: High — bug mentions above category norm, rating drift -1.94 ★ (recent 50 vs lifetime), dormant (944d 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 12-22× monthly = $60K-$110K. Portfolio play ($46K/mo combined) commands premium. Discount applied for operational risk..

About this analysis
Why low confidence: only 1 rating · no founder-verified revenue (model estimate only) · revenue figure is directional only.
📌 Final verdict — read this before you trust the numbers above
Hazard Perception is a very early-stage iOS app in the news space with weak public traction — only 1 rating, 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.
