It has several views:

Cannot get it installed on iPad Air
Ed Reingold

I used this app with no problems on my old iPad, but I cannot get a proper installation on my new iPad. It keeps giving me an error message that it cannot extract the file. The only version that will install is a low res, badly distorted view.


No longer works since iPhone X

Have not been able to get this to open the xml file to setup on the iPhone X. Hope it gets fixed soon.


So great for RPN users

This is definitely a five star app; once you've had a model 48 you will never go back. Unfortunately, it seems to have a date bug and won't work in 2013. Hopefully the author makes an update to address this! Update: it was fixed. Unfortunately now in 2018 I am having problems again. Would gladly pay for an update as this is one of my go to apps. Update: re downloading fixed it. Woohoo!


Please add "Ignore Mute" switch
Hamp63

I enjoy the app. I wish it had one thing ... an "Ignore Mute" switch in settings. My 41CX app has this feature. For those of us who keep our phone in silent mode, the "Ignore Mute" switch allows the calculator sounds to still work. Silent mode is mainly used for unexpected sounds such as ringing phone, etc. However, when using calculator, all key sounds are fully expected. The key sounds are, in fact, extremely useful as feedback since there is no tactile feedback. As a silent mode user, I currently must turn on sounds each time I use the calculator and then turn off when I'm done (hopefully not forgetting to turn off). The "Ignore Mute" switch would eliminate the need for turning phone sounds on and off. Thanks.


Cool

Cool free app nice to have the rpn on the phone. Takes a long time to load though


Broken, again...
Jammin777

This calculator is no longer reliable. The keyboard makes clicking sounds as you press the keys but often the key press is not registered by the calculator. You may type "1147" but the display shows "147" even though four clicks were heard. Can no longer trust the results without carefully monitoring the exact input on the screen.


Great HP-48
DJ in BKLYN

I liked this so much I bought the premium version (m48+) just to support the developer, even though the HP-48GX and "Don't Panic" skin was all I was interested in. Excellent.


Stopped working
Forced to rate143

Loved it so much then it just stopped working.


iOS 11 broke the app
HRadioMatt

I have loved this app up until iOS 11. Maybe I shouldn’t have upgraded. I hope the developers can get a fix soon. If you are on iOS 10 or 9, this is such a great app!!


HP48 in my pocket
Generush

My go to calculator for iPhone. I’ve been using an RPN calculator almost 30 years, and this one gives me that familiarity.
