💰 Revenue: Modest — $3K - $7K/mo · MID tier · medium confidence, trajectory unclear.
⭐ Quality: 4.6★ across 1,426 reviews — strong (top 10%).

📈 Growth: ⚠ last update 2510d ago — possibly dormant.
⚠️ Risk: Moderate — dormant (2510d 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 ($24K/mo combined) commands premium.
