Do you actually need to install our App ?
In a word...no!
The look and functionality is exactly the same in the apps. as if you just use FMG in your mobile browser.
The site is fully mobile responsive, so works like an app anyway.
But if you do want an icon on your phone and an app-like experience, then the solution is to just add FMG to your homescreen as a PWA (Progressive Web App - they are the future!) on Apple or Android, and you'll get a great user experience.
(Images show how to manually add PWA to your homescreen, but you may also get a "pop-up" add to homescreen notification).
But.....if you do want the app then you can download the Android App fom the Play Store HERE
There is a dedicated iOS app in development, we will let people know when it's done.
