PC app no longer present

Good evening everyone,

I recently found an old fitbit charge that i thought i'd try and sync up to my computer.

However, it would appear Fitbit (Now owned by the (insert very nice title) people at Google) has since removed the app for the watch. As a result, this thing is now a paperweight, which is a shame as i find it quite useful despite daily driving an apple watch.

Is there any way to fix this and find an app, or am i just going to have to find some other way. All i need it to do is sync the time since it is way out of wack. Any simple ways of doing that.

I do have the dongle that came with the watch and the charger but there's no app to use the watch.
