## Most critical reviews (3 lowest-rated)

### 3/5 — Nice but too cluttered looking

*2026-05-09*

I have pretty much every HP emulation that has shown up on the App Store and I still have numerous real ones including a 15, a 16, a 34, a 48, a 67 and a 97 and two from Swiss Micro including their 42. My introduction to computing was the 25C some fifty years ago.

While this new 40 has some incredible functionality, cosmetically it looks far too cluttered. Maybe it’s the wrong fonts, or the fonts are too big and though it’s clearly very powerful, it loses  the HP realism, which frankly is a big reason to collect them.

I would love to see an update that addresses the cosmetics.

### 5/5 — Cool program

*2025-09-13*

If you’ve used the hp48, 28, or 50g then do yourself a favor and try it.  Much more advanced but faithful to the vision for the 48sx.  This is a much more appropriate successor to the hp48sx than the 50g was.

### 5/5 — Amazing

*2024-09-22*

This is an incredible calculator whether or not you have used an HP48. It does everything and is easy and intuitive to use, and is getting regular updates. Amazing work!
