From Brad Linder at Liliputing:
The Amazon Appstore allows you to download and install apps on Amazon Fire tablets and Fire TV devices. But the Appstore actually predates the Amazon Fire ecosystem. Amazon first launched the Appstore in March, 2011 as an app that could be installed on Android phones and tablets. The first Amazon Fire-branded tablet didn’t launch until half a year later. Fourteen years later Amazon has announced that it’s discontinuing the Appstore for Android.
I learned two things here. Firstly, while I know that Amazon’s Fire OS is based on Android and I have run F-Droid (a free and open source Android app store) on Fire devices, it had never occurred to me that Amazon promoted its Appstore on regular Android devices. Note that I run GrapheneOS on my phone with no Google Play Services, so I am not up to date on the proprietary app stores. Secondly, I was even more surprised to learn that the Amazon Appstore pre-dates the first Fire OS device, meaning it was originally released for main-line Android devices. Go figure. I have some limited experience with the Amazon Appstore from my old 2013 Kindle Fire HDX (see my one and only Amazon Appstore visual novel review) and BlackBerry Classic, both of which ran Android-derived operating systems and shipped Amazon Appstore as their default app stores.
