View a catalog of third-party apps to sideload on BananaHackers Store.
According to How-To Geek, sideloading is 'the practice of installing software on a device without using the approved app store or software distribution channel'. You may want to do so because a cool piece of software is not available in the device's app store, either because it doesn't meet the app store's requirements, not available in your region, or you're a developer and looking to test your brand-new app before making it public.
This is where Android Debug Bridge (ADB) and WebIDE comes in. Every piece of electronic devices has some sort of special protocols for developers and engineers to communicate and perform special functions, including sideloading apps, and KaiOS devices are not an exception. ADB and WebIDE are handy tools for engineers to decode those protocols.
There are also alternative methods to choose from.
