The android app had stopped working for me a couple of months before the new Pebble came out, so my Old Pebble Time was at EOL, and unusable. The new Pebble app by Core devices made it work again.

Rebble didn't do that. They were effective only keeping the old devices on life support. Don't get me wrong, it's awesome that Rebble came along and extended the life of our Pebbles. I'm siding slightly more with Eric and Co. than with Rebble.
