  • 💰 Revenue: Marginal — $214 - $1342/mo · INDIE tier · medium confidence, trajectory unclear.
  • ⭐ Quality: 4.09★ across 1,425 reviews — solid.
  • 📍 Market: Not yet charting in any of the 9 monitored markets.
  • 📈 Growth: last update 272d 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-$17K. Portfolio play ($10K/mo combined) commands premium.
