- 💰 Revenue: Modest — $436 - $2727/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.0★ across 12 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: last update 335d ago — slow cadence.
- ⚠️ Risk: Elevated — bug mentions above category norm, rating drift -0.62 ★ (recent 50 vs lifetime).
🎯 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 = $19K-$34K. Portfolio play ($10K/mo combined) commands premium.
