Nice, I like this one. Disappointed the units converter doesn't have pounds and ounces as a target, though. It only does pounds or ounces, not both. I tend to see a lot of quantities specified as pounds and ounces at the same time in my day-to-day activities.
You can emulate a ti83+ with an app called Graph 89.
Dib2Clac is cool too
I've also been looking for some calculators and while I find some good interesting ones, all of them either look clunky or have a huge learning curve or are too simple. I want a simple scientific calculator, but they're all either too simple or too complex.
But, think about it. The calculator is designed to be a machine. Emulating that on a phone might artificially limit you. Maybe it's better if your calculator has a different user experience, maybe the UX for calculators needs to evolve. Try out the weird stuff.
A lot of these are great and this one came close, I found usability could be better.
Usually when I need a calculator it's when I'm doing something else, out in the rain etc. I'd prefer some more (higher contrast) theme options and at least vibration on keypress.
It's a beautiful calculator, but it's too much like typing on a glass slab.
I'm still using mathdroid. Which I have installed but cant find on fdroid anymore?
I can't seem find another Foss calculator app that doesn't think buttons need to bigger than my finger and 0-9 should take up 3/4 of the screen.... I love being able to see history of my past entries and have a button layout similar to an actual scientific calculator.
