User Reviews for RPN-35 SD

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.

Nice, but poor key touch

I’ve had HP35s for 45 years & my 3rd one quit working so it’s great to have a substitute. This looks and works just like the real thing, however I’m very disappointed in the touch. Touch area of the keys is so small that I have to enter numbers very slowly, sometimes having to click multiple times to get a key to fire. I’ll be using another rpn calc that has better input even though I paid for this one. Too bad, I really liked this one otherwise. (Using this on an iPod 6.)

Terrific!...

Great emulation of the original classic HP calculator. If you love these old calculators, check out the CuVee apps...

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.

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.

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.

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 (more than $2,200 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 • Enhanced memory mode • Key-click and key-glow, both optional • Swipe left across display to correct wrong number entries • Cut/copy/paste display value • Display stack registers and all 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 - 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: a number of known arithmetic bugs Enhanced memory mode - non-volatile stack and registers - use registers 1 through 9 with HP-45-like register arithmetic - register 0 works as LastX register
