## Most critical reviews (4 lowest-rated)

### 5/5 — Greatest evolution of great HP calculators of the past.  Wish there were a Windows PC emulator.

*2026-03-07*

Christophe, would it be possible to create a Windows PC emulator of the DB50X?  It would be helpful for me to have this open when working in 3D CAD.

### 5/5 — Some keypad confusion

*2025-04-11*

The 1/x key should have e^x top left yellow and ln top right blue. The root x key should have x root y top right blue. Edit c.

### 5/5 — Not an HP48 clone, better!

*2024-11-23*

This guy started trying to make something similar to the HP48 family of calculators, but is ending up with something better.  It is designed to be installed on a swissmicro calculator, but this IOS app works the same and is nicer than the other HP48/50 emulators.

### 5/5 — Goodbye HP 28s —> HP50g… Hello DB50X

*2024-10-20*

Finally we are getting a modern calculator that carries forward the brilliance of the HP 28s family.  Great work with the unit conversions and looking forward to creating a family of equations that can share common variables!  Then I can put my tired HP50g that away with my original HP28s!  I’m finding that the innovative menu system is intuitive and quickly familiar.   Thanks
