- 💰 Revenue: Modest — $4K - $9K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.36★ across 942 reviews — below category median.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: ⚠ last update 953d ago — possibly dormant.
- ⚠️ Risk: High — bug mentions above category norm, rating drift -2.12 ★ (recent 50 vs lifetime), dormant (953d 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 = $77K-$141K. Portfolio play ($40K/mo combined) commands premium. Discount applied for operational risk..
