The UI on this calculator is the best for the HP experience. After moving up to marshmallow and a 6p the freezing up has started making it unusable. Have reached out to developer but no response yet. UPDATE 3/2017. Developer has resolved issue and I have yet to find any problems. A great app that is very useful and appreciated! Great work!!
I have a 'Redmi Note 2 Prime' cellphone running Lollipop 5. Droid48 1.61 froze almost immediately. I have been trying out this latest version, Droid48 1.72, for a week now, and it has not frozen at all, and the key responsiveness is fine. If anyone has problems with key responsiveness in Droid48, the following might make a difference: 1) Click on 'Settings' on your cellphone. 2) Find 'Accessibility Options'. 3) Turn off 'Magnification Gestures'.
Recent update is frustrating to use due to missed keystrokes, despite the haptic feedback firing for each tap. Otherwise a very complete scientific calculator. Switching back to an infix calculator, after using this one for years, has made me realise how natural RPN has become for me.
I just love this app Once I got used to using the Polish notation (20+ years ago while in Engineering) I couldn't see myself using any other calculator. This app lets me carry myself beloved HP48G with me everywhere
It simply just works. Not much to add. I still use my old 48GX, but this one follows me around everywhere I go - and just works. Perfect. Update 21/12-2016: Just got the latest update and now it is rather slow in accepting my keypress. Needs to press several times to get it working. Looking forward to the next update, which hopefully fixes the problem. My phone is an older Galaxy S4 mini with Android 4.4.2
I use this every day and it brings back the experience of the HP 48 - great app. There are a few minor errors in the 48GX skin (not the bitmap) - maybe these can be corrected. I have listed them below in order of the keys on the keyboard: NUM should be ->NUM; nth root of y should be xth root of y; 10^n should be 10^x; y^n should be y^x; e^n should be e^x.
Trying some things to help with the crashes/freezes
Excellent scientific calculator with expressions, fractions, repeating decimals.
