I find current input keyboard for smath on android quite deceiving, to say the less:


I wish we had a skinning system similar to the Emu48 emulator (there's no better calculator emulator for Android), which allows the user to fully customize the calculator keyboard.
I think it would be really simple to do (at least for "non-shifted keys"), and I guess we'll have to wait:

That is just a matter of taste, I like TI-89 Titanium emulator much more.
You have to download firmware for TI-89 to make it work, it is just a shell for calculator.

Yes, I know of both, and more than taste, it's a matter of which one you know how to handle: i owned an hp48... since 1993 (up to less than a month: it died after trying to open it to fix serial port ). I also used emu48 on a pocket pc since 2004... so for me "nothing tastes better than a hp48" (not really).
Being frank, a TI89 Titanium in amazon costs around 240 €, whereas a HP50 (also emulated in emu48) costs 400 €, so there must be something special in that calc.
But the issue was with the Smath keyboard in android: it's pityful. And after testing it both on a phone (Android 7.1) and a tablet (Android 4.2.2) I am even more deceived: the keys hardly work, i mean I was unable to input numbers, either from the standard keyboard on the mobile, or from the extended keyboard in Smath. It needs a full check.

BTW, do you know of any web sites providing (good, and free) Engineering Handbooks/ebooks/function packs, with at least a good pack of (properly sorted) maths and mechanical engineering formulas, preferably for Smath or for Mathcad?
The Reference Handbooks by Andrey Ivashov and Martin Kraska are good but only for basic maths, and the examples already included with Smath and in the forums too; the ptc mathcad community also provides many good examples; but I only found one web page providing a bunch of worksheets (https://sites.google.com/site/mathengjmg/download/worksheets), and nothing like the ones in mensys (these are f.c...ly expensive!)
