Could be better


It's great, other than not being able to manipulate the hexi value on the colour wheel. Trying to guess and drag your finger around to find the value you want is bollocks. Oh yes, they're not that accurate either.

Pretty cool


I really like the setup for the binary calculator. Very easy to use and quick too. But nice work bro, that is, assuming you wrote the algorithms yourself. Helps me think back to remember how to convert them back and forth. :)

Pls update it to ios 11+


I can’t even open the apps now cuz it keep saying the dev need to update it to ios 11+
