- 💰 Revenue: Modest — $7K - $15K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.67★ across 2,706 reviews — solid.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: last update 347d ago — slow cadence.
- ⚠️ Risk: High — 3.1% refund mentions, scam/fraud mentions detected, bug mentions above category norm.
🎯 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 = $123K-$227K. Portfolio play ($39K/mo combined) commands premium. Discount applied for operational risk..
