💰 Revenue: Healthy — $400K - $2200K/mo · BIG tier · medium-low confidence, trajectory unclear.
⭐ Quality: 4.01★ across 32,770 reviews — strong (top 10%).
📍 Market: Not yet charting in any of the 9 monitored markets.
📈 Growth: Insufficient signal to assess trajectory.
⚠️ Risk: Low — no material risk signals detected.

🎯 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 = $18.0M-$32.0M.
