- 💰 Revenue: Modest — $579 - $3622/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 3.21★ across 35,236 reviews — solid.

- 📈 Growth: ⚠ last update 1012d ago — possibly dormant.
- ⚠️ Risk: Elevated — dormant (1012d since update).
🎯 For competitors: Vulnerable. Quality drift + slow updates create a clear opening for a fresh competitor with active dev cadence.
💵 For acquirers: Estimated asking range 18-32× monthly = $26K-$46K. Portfolio play ($2K/mo combined) commands premium.
