- 💰 Revenue: Modest — $3K - $7K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.89★ across 92 reviews — weak — significant quality concerns.

- 📈 Growth: ⚠ last update 682d ago — possibly dormant.
- ⚠️ Risk: Moderate — dormant (682d since update).
🎯 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 = $90K-$160K. Portfolio play ($126K/mo combined) commands premium.
