Microsoft have announced that they are ending its health applications which is bad news for anyone who ownes a Microsoft Band watch.
From May 31st 2019 you will no longer will be able to use any apps that were designed for the watch, it also means any internet based apps that you use will no longer work.
It is not all so bad though as you will still be able to use the watch for basic functions, if you have important data from any of the apps you should use this LINK
If you were looking at buying this watch we suggest not to do so at any price and find something else such as the Honor band 4 and others.
Microsoft have the Band 1 and 2 for sale and expect they will still be on sale after the end of May.
