- 💰 Revenue: Healthy — $280K - $1540K/mo · BIG tier · medium-low confidence, trajectory unclear.
- ⭐ Quality: 4.86★ across 3,729 reviews — solid.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: Insufficient signal to assess trajectory.
- ⚠️ Risk: Moderate — 9% subscription complaints, rating drift -1.22 ★ (recent 50 vs lifetime).
🎯 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 = $12.6M-$22.4M.
