- 💰 Revenue: Modest — $1K - $7K/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.14★ across 66 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: ⚠ last update 437d ago — possibly dormant.
- ⚠️ Risk: High — 3.3% refund mentions, scam/fraud mentions detected, bug mentions above category norm.
🎯 For competitors: Vulnerable. Quality drift + slow updates create a clear opening for a fresh competitor with active dev cadence.
💵 For acquirers: Estimated asking range 12-22× monthly = $36K-$66K. Portfolio play ($32K/mo combined) commands premium. Discount applied for operational risk..

This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
