- 💰 Revenue: Modest — $3K - $7K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.17★ across 230 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: Insufficient signal to assess trajectory.
- ⚠️ Risk: Moderate — scam/fraud mentions detected, rating drift -1.39 ★ (recent 50 vs lifetime).
🎯 For competitors: Mixed picture. Worth competing if you have a clear UX or pricing edge — otherwise crowded segment.
💵 For acquirers: Estimated asking range 18-32× monthly = $90K-$160K. Portfolio play ($36K/mo combined) commands premium.

📝 About this app
Type a number, get an answer. NumPad adds a full numeric keypad to every keyboard on your phone — and now it computes as you type: finish "1200*0.0825" and the answer floats above your cursor before you even reach for the "=" key.
NEW IN 2.0: LIVE MATH, WHILE YOU TYPE
Start typing an expression — "84.50*1.18", "250-20%", "3*12+40" — and a floating result chip appears above the cursor before you finish. Tap it to insert the answer, or keep typing to refine the expression. It's the same calculator engine that powers the "=" key and Siri, just faster to reach.
