- 💰 Revenue: Modest — $17K - $37K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.58★ across 62,826 reviews — strong (top 10%).
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: Insufficient signal to assess trajectory.
- ⚠️ Risk: High — 3.8% refund mentions, 5% subscription complaints, scam/fraud mentions detected.
🎯 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 = $303K-$556K. Portfolio play ($40K/mo combined) commands premium. Discount applied for operational risk..
