Is there a way to continue using the BASIS B1 Band?

Hi there,

I have been using a BASIS B1 Band for activity and sleep tracking until the mybasis web application and the app were shut down following the recall of BASIS Peak.
I have tried out various other activity and sleep trackers since then but found nothing that I liked as much as the BASIS Band.
Therefore I was wondering if there is a way to continue using the Band without the app and the web application.
For the ZEO sleep tracker some dedicated people programmed software and apps that made it possible to continue using the device even after the web application was shut down.
Does anybody know if someone did something similar for the BASIS B1 Band and/or the BASIS Peak?
I already searched the web but was unable to come up with a solution.

Many thanks in advance for any input on this!
