- 💰 Revenue: Modest — $6K - $13K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.67★ across 1,533 reviews — solid.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: Insufficient signal to assess trajectory.
- ⚠️ Risk: Elevated — bug mentions above category norm, rating drift -0.67 ★ (recent 50 vs lifetime).
🎯 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 = $106K-$195K. Portfolio play ($95K/mo combined) commands premium. Discount applied for operational risk..
