The latest update has made the app very slow and unresponsive and forced me to go back to a real HP48 for engineering work. Button presses work but must be held in for far longer than before.

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

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 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'.

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!!
