- 💰 Revenue: Modest — $3K - $7K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.81★ across 1,016 reviews — solid.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: dev shipping weekly.
- ⚠️ Risk: Moderate — rating drift -0.35 ★ (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 = $90K-$160K. Portfolio play ($69K/mo combined) commands premium.
