The very specific focus of F-Droid is to offer free and open source software (FOSS) Android apps. It’s basic, but apps on the store are categorized, and the list is searchable. You’ll find a big selection of free apps here, all of which promise no tracking, no ads, and no dependencies. It’s worth checking out for free apps, especially if you support the open source movement. Android App
ARChon isn’t a traditional emulator. You install it as a Google Chrome extension. It then gives Chrome the ability to run Android apps and games (albeit with limited support). It’s not an easy emulator to get running. You’ll have to install the thing to Chrome. From there, you have to obtain APKs and load them in. As an added rub, you may need to use a tool to change the APK in order to make it compatible. There are a lot more steps to make this work than most other Android emulators for PC. On the plus side, though, it works with any operating system that can run an instance of Chrome (Mac OS, Linux, Windows, etc). We linked to the official GitHub where you can find detailed instructions for its use. Android App

There is probably a greater enticement for developers because Slide ME offers the chance to target a wider international audience. Apps are also more likely to be discovered, thanks to the search filter options. Developers can set prices and choose to offer their apps for free. There is also a Slide ME ad network, and it is even possible to get a greater percentage of the revenue generated by your app with Slide ME — potentially more than the standard 70 percent you’ll get through most other app stores.
