For the activity alert use https://play.google.com/store/apps/details?id=pl.w9.moveupalert works really great and is not dependant on the phone. Besides from that, what does Google Fit not do what Apple does?
https://play.google.com/store/apps/details?id=pl.w9.moveupalert Works really great. Does not need a phone and resets it self if you get up and do something. And in my experience it's really accurate. But: There were some updates last week and now my watch loses battery faster, but I think the reason is another app that recently updated. Wanted to give a heads up /warning anyway.
As I initially installed the app, there was no impact on battery live.

I've been using that, seems to work pretty well for the most part (would be nice if you could change the reminder frequency.. Kind of annoying sometimes)
Plenty. Try https://play.google.com/store/apps/details?id=pl.w9.moveupalert&hl=en for starters...
