💰 Revenue: Marginal — $351 - $2196/mo · INDIE tier · medium confidence, trajectory unclear.
⭐ Quality: 4.64★ across 11 reviews — weak — significant quality concerns.
📍 Market: Not yet charting in any of the 9 monitored markets.
📈 Growth: Insufficient signal to assess trajectory.
⚠️ Risk: Low — no material risk signals detected.

🎯 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 = $15K-$28K. Portfolio play ($3K/mo combined) commands premium.
