On February 7, 2018, Foobar2000 Copilot Lite was globally published to the Microsoft App Store. This is the free version of Foobar2000 Copilot. It has the same features as the paid version minus the flashlight option. It includes a single adDuplex ad at the top of the search page. It will run on WP8.0, WP8.1 and Windows 10 mobile.

Unfortunately, if you are using a WP8.0 or WP8.1 phone and using the phone's built-in store app to search for it, it does not appear at all-- not for any of the search terms I submitted to Microsoft when uploading my app. So it is in effect invisible.  My original Foobar2000 Copilot app does appear in the phone's store app search.

It does work if you are using a Windows 10 mobile phone and using the phone's store app.

Microsoft is currently looking into why this is.

But should you want to install the app to your WP8.0 or WP8.1 phone now, you can open a browser window on your phone, and go to the Microsoft store and search for it there using the search button at the top of the screen. That works, versus using the built-in store app that is installed on your phone.

Just typing in foobar2000 should bring it up in a list. You can then click on it from the found list and then proceed to install it.

Or on your phone in a browser window, you can also just click on the following direct link to it in the Microsoft app store :

Hopefully Microsoft can resolve this soon, so Foobar2000 Copilot Lite will be visible in the store using the phone's store app for WP8.0 and WP8.1 phones.
