- 💰 Revenue: Modest — $949 - $5933/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.8★ across 46 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: Insufficient signal to assess trajectory.
- ⚠️ Risk: Low — no material risk signals detected.
🎯 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 = $42K-$75K. Portfolio play ($19K/mo combined) commands premium.

📝 About this app
NoteCrypt combines strong 256-bit AES encryption, and rugged simplicity. NoteCrypt will prevent even the most determined and well-resourced attacker from accessing your notes, even if they physically possess and can unlock your device.
NoteCrypt goes to extreme lengths to secure your notes:
- Applies 256-bit AES encryption to the full notes database
- Uses the PBKDF2 key derivation and stretching function
- Does not store your password, making your notes impossible to decrypt without it
- Does not have cloud integration or login
- Does not use analytics… View full description on the official store →
