- 💰 Revenue: Modest — $1K - $7K/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.33★ across 89 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: ⚠ last update 1050d ago — possibly dormant.
- ⚠️ Risk: Moderate — dormant (1050d since update).
🎯 For competitors: Mixed picture. Worth competing if you have a clear UX or pricing edge — otherwise crowded segment.
💵 For acquirers: Estimated asking range 18-32× monthly = $56K-$100K. Portfolio play ($40K/mo combined) commands premium.
