Sideloading APKs Using APKPure
SideQuest allows you to sideload APK apps from a PC onto your Quest using a USB cable. APKPure allows you to skip the cable and sideload APK files that you downloaded straight onto the Quest without needing a computer. You can download the APK (whether through a website, Google Drive, etc.) then install it using the APKPure app. Note that the APKPure app itself needs to be sideloaded first, most likely using a tool like SideQuest.
In addition to allowing you to sideload your own APK files, APKPure includes a marketplace of APKs that you can download. You can install Android apps that might have only otherwise been listed on the Google Play Store onto your Quest. Your experience using mobile apps on the Quest may vary since these apps were designed to be run on mobile phones, but you may find some of the productivity-based apps to function well on the Quest! For example, you can download Discord, Reddit, TikTok, Twitter, etc. Visit APKPure.com to see the full marketplace offerings.
Before you begin
First-time Setup (Enabling Developer Mode)
In order to sideload APKs to the Quest, Oculus requires that you enable developer mode. They make you jump through some hoops in order to get this done the first time, but once developer mode is enabled you can skip these steps each subsequent time you want to sideload an app in the future.
