Good however…
Doesn’t show the bottom row of buttons on my iPhone 12 mini
Description
On January 4, 1972, Hewlett-Packard announced the HP-35, world's first scientific calculator small enough to fit in a pocket - more precisely, Bill Hewlett's shirt-pocket. The HP-35 was an immediate hit with students, engineers, and scientists. Despite its steep price of $395 (about $3000 today), it sold ten times better than anticipated in the first year.
Experience this unique calculator that won HP the prestigious "IEEE Milestone in Electrical Engineering and Computing" in 2009.
Features:
• Photo-realistic look-and-feel
• Three skins: version 1, versions 2 & 3 (1973) and final version 4 (1974)
• Vintage mode and Enhanced mode
• Key-click and key-glow, both optional
• Swipe left across display to correct number input errors
• Cut/copy/paste display value
• Display stack registers and memory registers
• All decimal points but one light when iPhone battery charge drops below 5%
Vintage mode
In this mode, peculiarities of a real HP-35 are simulated:
- original speed of operation
- stack register Z copied to T on trig functions
- leading zeros may be entered; zero can be made negative
- a negative number may be entered by pressing CHS before or after the number
- a keyboard entry or RCL immediately following STO does not raise the stack
- for version 1 only: simulation of a number of known arithmetic bugs
Enhanced mode
- non-volatile stack and registers
- use registers 1 through 9 with HP-45-like register arithmetic
- register 0 works as LastX register

Not good for scientific notation
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 app
Great simulator. However the LED display is a little dim.
Simply the best
Very fairly priced and perfectly designed and developed app. A master piece from the best.
great memories
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.
Extremeley pleasing HP-35 experience
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.
Needs an update
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.
Love this emulation!
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.
RPN-35 SD
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.
Terrific!...
Great emulation of the original classic HP calculator. If you love these old calculators, check out the CuVee apps...
