- 💰 Revenue: Modest — $3K - $7K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.69★ across 284 reviews — below category median.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: ⚠ last update 610d ago — possibly dormant.
- ⚠️ Risk: High — scam/fraud mentions detected, rating drift -0.67 ★ (recent 50 vs lifetime), dormant (610d 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 12-22× monthly = $60K-$110K. Portfolio play ($11K/mo combined) commands premium. Discount applied for operational risk..

🌍Geographic ReachNot ranked
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.
📝 About this app
Addition & Subtraction. Solved.
From the innovators who bring you Times Tables Rock Stars, comes a highly engaging platform for learning to add and subtract… NumBots!
NumBots is all about every child achieving the “triple win” of understanding, recall and fluency in mental addition and subtraction, so that they move from counting to calculating.
Suitable from Year 1 (UK) or Kindergarten (US) upwards. Younger players will be able to access the early stages from a mathematical point of view but will find it increasingly harder to reach the level of fluency required to make continued progress.
