(Self promotion) if people like the Casio style calculators, my app is heavily influenced by Casio’s scientific calculators. The editor works almost exactly like theirs, but it has a modern keyboard that’s optimised for touch screens. The rendering uses the LaTeX font too<p>As well, you get a few dedicated modes, like unit conversion, date calculations etc.<p><a href="https://jacobdoescode.com/technicalc" rel="nofollow noreferrer">https://jacobdoescode.com/technicalc</a>
