  • 💰 Revenue: Modest — $3K - $7K/mo · MID tier · medium confidence, trajectory unclear.
  • ⭐ Quality: 4.33★ across 178 reviews — solid.
  • 📍 Market: Not yet charting in any of the 9 monitored markets.
  • 📈 Growth: ⚠ last update 2832d ago — possibly dormant.
  • ⚠️ Risk: Moderate — dormant (2832d 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 = $90K-$160K. Portfolio play ($7K/mo combined) commands premium.
