### 4/5 — Display problem on iPhone 13 Pro

*2023-02-26*

I love the iPad version of this app. On my iPhone 13 Pro ist the display off, there is a glitch and the display of the results are not readable. I am.happy to provide a screenshot. I'd appreciate if the developer could look at the problem, thanks.

### 4/5 — No rotation on iPad is a shame

*2020-04-23*

Like all of the emulators from CuVee this not only reproduces the ground-breaking wonders of long ago from Hewlett Packard,  but turbocharges them with modern day computing power. It is simply superb!

My only gripe is minor and has already noted by the developer. Unlike the HP-70HD - which I also have (of course!) - it does not rotate to landscape view which seems a little inconsistent with its 5 star cousin.

That said, My previous 3 star rating was harsh: this IS a fantastic calculator; but for me its slight loss of practicality sees it just fall just short of 5 stars.

**Developer response:** iPhones are too small to allow operating portrait-oriented calculators in landscape mode in any reasonable way. Unless the layout changes totally in landscape mode, which is not the idea of these simulators.
If you run RPN-70 SD on an iPad, please note that there exists an iPad-only version, RPN-70 HD, which fully supports landscape mode.

### 4/5 — Hübsches Tool

*2017-10-16*

Eine sinnvolle App! Leider konnte ich nicht heraus finden, wie man eine durch den Befehl „STO“ gespeicherte Zahl wieder zurück holen kann (Der Befehl „RCL“ für recall fehlt (konnte ich nicht finden). Trotzdem 4 Sterne.

### 5/5 — Love it

### 5/5 — A Very Useful and Classic Tool

*2021-05-31*

Many sincere thanks to the development team.

### 5/5 — Für HP gewohnte Nutzer

*2020-04-14*

Schönes einfaches gut nutzbares Tool. Für HP Gewohnte unentbehrlich.
Es wäre schön, wenn der Entwickler auch einen HP-Rechnet mit den + - : * Tasten auf der rechten Seite. anbieten würde

### 5/5 — Amazing! Perfect emulation of a classic calculator

*2019-03-02*

I have several Cuveesoft calculators and all are excellent. I use the RPN-70 SD for personal finance.

### 5/5 — A Perfect Calculator App

*2019-01-24*

Perfect RPN App for my needs. Simple interface, but has enough basic financial functions to meet my needs. True to the original. Love the extra memory !
