Kalkyl review

Muff Winwood

Nice, clean and simple. I love it. I wish there was a way to do % on it with the % button. I hope it is available in a future update.

Developer Response

Thank you and great to hear that!
Percent is a bit tricky when it comes to expressions. It’s for example not really 100% clear to everyone what “100+100-20%” means (is it 180 or 160?), same thing for multiplication and division like “100+100*20%” (is that 120 or 140?).
It will be included, but in a way that prevents these kind of mistakes - so it’s going to take a little bit of time to get everything sorted out for a solution that works flawlessly.

Nice and simple to use
