LXVII for Android

I hope they can roll things back. The latest update made the app unusable - and that's not even including the color scheme that makes me want to poke my eyes out. Please fix it! I had no issues previously...

The display is not showing numbers. The upgrade to 17.2 is not working the way the previous version did. Please fix it. Running IOS 10.13.6.

I have a 2013 Android running Catalina 10.15.5. This app crashes everytime I try to use the show registers feature. Can you fix it?

I love this calculator when used with the present of the register. I have a 2018 Android with 2.9GHz 6-core. When I try to show the register, the app crashes every time. I have never seen the register on this calculator because the app crashes always.

Unless you’re familiar with the HP-67 - or have its manual - this calculator is not very useful to you unless you are willing to invest the time mastering it blindly. Certainly a person schooled in the sciences can figure it out - all the functions are there - but why should one have to do this? And I would bet the manual for the HP-67 exists somewhere on the internet. But complexed tools, such as this, usually come with documentation. No documentation here. None. Personally, I consider my time too valuable to spend an inordinate amount of it learning to use what is a basic but complicated tool when alternatives abound. Alternatives with appropriate documentation.
