💰 Revenue: Marginal — $207 - $1297/mo · INDIE tier · medium confidence, trajectory unclear.
⭐ Quality: 4.1★ across 1,200 reviews — solid.
📍 Market: Not yet charting in any of the 9 monitored markets.
📈 Growth: last update 225d ago — slow cadence.
⚠️ 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 = $9K-$16K. Portfolio play ($2K/mo combined) commands premium.
