Personal Comments by Reviewer
Some users commented on the fact that the app had the same feeling as the retro scientific calculators from the 80's. As someone who used a scientific calculator during that time period I strongly agree. It felt comfortable, simple, and fun to use. I loved that no matter how complicated the equation was the calculator could handle it with ease and speed. The list of features is impressive for a free app and once you start using it you'll find way more features that weren't even listed. I also liked that you could adjust settings such as using the comma as a decimal point, or turning the key click sound on or off.
