RPN-35 SD

Das schnellere Einschalten war eine gute Idee - hm darauf habe ich l a n g e gewartet...!

Doesn’t show the bottom row of buttons on my iPhone 12 mini

I noticed when entering scientific notation, this app will not let me enter a negative exponent. When I press the change sign key nothing happens. A little problematic when doing computations involving scientific notation. Everything else the calculator works fine. This one issue is why I gave you only 3 stars instead of 5.

Great simulator. However the LED display is a little dim.

Very fairly priced and perfectly designed and developed app. A master piece from the best.

I saved a long time while I was in high school in the 70s to buy one of these. IIRC it was $400. I finally got it and tried every formula I knew, it was fantastic. I went on to Purdue as an EE student and used this one to win an HP45 in their annual Calculator Olympics. Then I used that one to win an HP67. The next year they banned me from entering - the best honor of all. Unfortunately I don’t have them any more but this app fills that old desire perfectly. Thanks for the memories, CuVee, very well done.

I'm using this on an iPhone 11 Pro Max. The ergonomics of the HP-35 — e.g., the number, size, and placement of buttons — really shine with this app and this screen size. Holding up an actual HP-35 and the app, you can even appreciate the lineage which goes all the way back to Steve's cold call to Bill Hewlett.

Have been using this emulator for a couple years and was really happy with it until this last iPhone software update. The display is now chopped off at the bottom so is really unusable. Hope this gets fixed.

I’m almost irrationally happy with this app. The HP-35 was my first calculator, purchased in 1975 while I was a Chem major in college. I spent the previous years using slide rules and trig table. I was fascinated by the RPN entry and how it could generate trig values on the fly. I’d still have it if it hadn’t been stolen. Sad. Because they didn’t steal the charger too. So they played with it till the batteries ran down then it became a small brick. I am a university professor now and I just used this emulation to total test scores! How fitting! Thanks so much for this emulation!!! I am grateful.

This is an excellent implementation of the classic, award-winning HP 35 calculator which was introduced in 1972 for $395. I love it! Well-done Cuvée! Please write an app for the HP-80 calculator.
