No landscape

Apps that will not switch to landscape on an ipad are worthless!

Need more functionality

Changing between modes deletes the input. I need to use and dec interchangeably eg. H1A + dec254.

DevCalc

Very handy. My only criticism is when you have a binary number such as “1011.011”. There isn’t a decimal point on the calculator. Other than that it’s great, thanks.

Good app but not for hex colours

Designers use 6 digit hex. This handles it well, but copy for pasting into other apps is no good. It puts spaces between the hex pairs. So if you want to copy the colour FF560A it copies as “FF 56 0A” which cannot be pasted into any other app. Pity, because this would be the best out there otherwise
