- 💰 Revenue: Marginal — $244 - $1528/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.7★ across 3,147 reviews — strong (top 10%).
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: dev shipping weekly.
- ⚠️ 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 = $11K-$19K. Portfolio play ($14K/mo combined) commands premium.
