Amazon last month removed its Windows Phone app from the Windows Store search results and announced that the app won't be available for download after July 25. It can still be downloaded with a direct link. Existing users will be able to use the service until August 15 when the it will be killed off for good.
Amazon revealed the news via emails sent out to current and past users of its app. This is what the email says:
Our records indicate that you have previously installed the Amazon App for Windows Phone from the Microsoft App Store.
We will be retiring the app you currently have on your device, meaning its contents will no longer be updated. You will still have access to the app until 15 August, 2016.
We encourage you to visit Amazon.co.uk on your mobile browser where you will have access to our newest shopping features and customer experience. We look forward to seeing you again soon.
As you can see from the email, Amazon recommends that Windows Phone users do their shopping through the mobile version of the site. Interestingly enough, PayPal recommended exactly the same thing before it killed its apps for Windows Phone and Amazon Fire last month. Whether Amazon has a new app in the works, is currently unknown. If that's the case, it better be a universal one!
