- 📈 Growth: Insufficient signal to assess trajectory.
- ⚠️ Risk: Moderate — rating drift -1.41 ★ (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.
