## RPN Calculator 48 Reviews in Vereinigte Staaten

### ***** "Great product"
Anytime I don’t have my HP around. It’s a easy click open.
-- CWZercher, 2024-10-31

### ***** "Not the full functionality of an HP-48"
Doesn’t have the full functionality of an HP-48, but heck better than an infix calculator
-- KG2V, 2024-10-22

### ***** "Love it"
It’s perfect.
-- ontoxus, 2024-10-20

### ***** "Finally"
I am a retired engineer who likes my HP 48G that no longer works. RPN is my natural habitat and I usually have my iPhone with me.
-- Domenic52, 2024-07-09

### ***** "My go to calculator for years now"
Learned rpn on a 41cx so long ago. This app sits intuitively on an iPhone screen and is easily one of my favorite and most useful tools.
-- Aerial7, 2024-06-22

### ***** "Best RPN iOS calculator"
I’ve tried several free versions. I read the reviews and figured this one was worth the $4 risk.

No jankyness / bad UI. Mimics my old 48GX pretty well (minus the graphing features). Everything works as expected!

I don’t mind paying for software, especially if it motivates the developer to continue porting the app to each iOS release— (historically, a lot of my freeware apps have lost modern iOS support whenever Apple deprecates an old feature.)
-- Ryan Jacobs, 2024-06-01

### ***** "Perfect RPN Calculator"
Please keep updating it.
This is a perfect calculator!
-- jota58, 2024-04-25

### ***** "Exactly the RPN Calculator I Want on My Phone"
This app is far superior to the default iOS calculator app - mostly because it’s RPN. It does everything I need a smartphone calculator to do, and I don’t have to change the way I think about using a calculator. It works reliably and smoothly. It’s been the calculator app of choice on each of my last four iPhones!
-- MortReviews, 2024-03-25

### ***** "My Go To Calculator!"
This full feature scientific calculator is my go to calculator for everything. I love the RPN style of entry, science the classic HP 45 and 65 calculators I loved so much. It also has hexadecimal and octal modes that I used while working, not so much now that I am retired. Easy to use. Love the display.
-- Chuck Noren, 2024-03-08

### ***** "HP41 CV/CX has died"
Have a number of the 41 series and they have all finally died. 
This has been a good replacement although i haven’t explored it’s programmability.
-- NoelN, 2023-12-11

### ***** "Fantastic"
Finally! A calc app that replaces my old m48 app that was removed from the store. This has nice big responsive buttons and large 10 level stack with exactly the right amount of functions used most often.
-- scastria, 2023-11-29

### ***** "Please add haptic keyboard feedback support"
This app has everything. Could you please add haptic keyboard feedback? I turned off the sound as I want the calculator to be silent. Haptic feedback would be great to know when I have pressed a key.
-- laser425, 2023-10-23

### ***** "LIKE"
I just love this — best calculator ever.
-- Zalmai, 2023-10-05

### ***** "John  P.E."
Perfect for my use in the field. Convenient
-- John P.E., 2023-08-28

### ***** "One of most used apps I have"
Can’t live without it!
-- Augusto Rpo, 2023-08-03

### ***** "I love this calculator."
I only miss the SWAP button from the original HP calculators. Please consider adding it to a future version
-- gdelfino , 2023-07-10

### *---- "Function Keys"
Each key shows an alternate function(s) but it’s not clear how to shift to them. There is no manual explaining how to use this calculator  e.g. how to bring up tips. Once you purch this app it’s you can’t get a refund.
-- Craig Fleming, 2023-05-10

### ***** "Great pocket calculator"
I’m an old school RPN engineer. This is a great tool!!
-- Its too much trouble, 2022-11-18

### ***** "Perfect calculator"
As someone who owns multiple vintage HP48s, I wanted the same RPN features and look & feel on my phone. Most of the other HP calculator apps try to perfectly emulate the calculator which isn't practical on a phone. This app strikes the perfect balance of usability and respect for the original design.
-- RhetTbull, 2022-10-27

### ***** "Simple and works."
No unnecessary bells and whistles.
-- YamunaRiver, 2022-06-08
