This is a custom AppStore that allows enterprise staffs to browse and download enterprise Apps that are not available in the Apple AppStore.
It is as easy to use as the official AppStore – one click download, app update notifications, featured apps, etc.
It also uses app linking technique that I discussed in my tech blog to detect installed apps and switch between different apps.
A single-sign-on feature was also implemented to relief user from the pain of logging into different app.
This app shares 95% of the codes between iOS and Android version. They have identical UI and provides very similar UX.
