Hi all.

I've just released a free screen ratio calculator iPhone app on the UK store for e-learning and web designers.

Its a simple tool with just one purpose - to calculate a matching new width or height based on a given ratio, you can also choose from a list of common screen sizes or add your own.

Heres a link to the app store https://appsto.re/gb/zTPxgb.i

or search for Screen Ratio.

Enjoy!
