- 💰 Revenue: Modest — $3K - $7K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.31★ across 2,722 reviews — strong (top 10%).

- 📈 Growth: ⚠ last update 445d ago — possibly dormant.
- ⚠️ Risk: Moderate — dormant (445d since update).
🎯 For competitors: Strong subscription moat. Hard to outcompete on retention. Better angle: free alternative with one-time purchase, or feature parity for an underserved sub-niche.
💵 For acquirers: Estimated asking range 18-32× monthly = $90K-$160K. Portfolio play ($15K/mo combined) commands premium.
