- 💰 Revenue: Modest — $1K - $8K/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.67★ across 143 reviews — solid.
- 📍 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 = $61K-$109K. Portfolio play ($10K/mo combined) commands premium.
