- 💰 Revenue: Modest — $454 - $2838/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 1.83★ across 257 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: ⚠ last update 2214d ago — possibly dormant.
- ⚠️ Risk: Elevated — dormant (2214d 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 = $20K-$36K. Portfolio play ($2K/mo combined) commands premium.
