Instant apps are a great way to introduce users to native apps experience without the need of installation. App fragments called features can be downloaded quickly thanks to their size limitation (4MB). This brings great user experience to people who can't afford to install a whole application or don't want to download the whole app for one functionality. Simply assign app links to your feature modules. Now whenever a user clicks a link present in your Instant App schemas, and your app is verified, instead of opening the browser, the Play Store will download your feature, cache it and launch a portion of your native app.
