Title says it all. The ipad pro only loads it in portrait. And can’t split screen.

Been using the RPN system since 1971 and this APP meets the bill for my IPHONE

Quick, responsive and accurate keyboard. The familiar RPN functionality. Great product!

I had forgotten how good an RPN calculator could be. Fits perfectly on a phone screen like it was made for it. No more backtracking through fat finger errors. Awesome calc!

This is the only rpn calculator I have found for iPhone that: 1. Looks good on small iPhone SE 4 in screen. 2. Does engineering notation properly. 3. Doesn’t have any bugs. I wish I had found this before wasting money on hp prime for iOS.

Gives the basic RPN performance of the HP48 series calcs in a somewhat familiar interface. Wish it had a few more features (like units) but very good for everyday computing for people used to RPN. Greatly miss my HP48gx; it was solid and had a great ergonomic feel (you never missed a key input unlike can happen tapping a phone screen). Granted there was a ton of features on it I no longer use (need) but I would love to see a better 48 emulator app available (like the old i48 app).

I own several HP calculators, and even then I occasionally don’t have one handy. This is a smart and functional design that any engineer or any designer will appreciate.

I’m still getting used to the app, but it’s nice not having to force myself to use the regular calculator entry I have to force myself to use.

Not really appropriate to call it an HP 48. It is a good rpn calculator, but not what the name implies. Not programmable Not an HP48G or HP48S
