- 💰 Revenue: Modest — $859 - $5369/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 2.5★ across 43 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: ⚠ last update 1059d ago — possibly dormant.
- ⚠️ Risk: Elevated — dormant (1059d 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 18-32× monthly = $38K-$68K. Portfolio play ($11K/mo combined) commands premium.
