Check 8 - a single purpose calculator app

Hi guys

the prompt in the UI challenge was to create a calculator of some description but I wanted to make it interesting or personal to me.

So I thought to myself, "what calculation am I always doing" and thats checking if a number is divisible by 8 and Check 8 was born

I know you probably dont want to have to sign into your calculator app but I thought it was good practice to include it in the flow

feedback back appreciated
