I've registered for the app already. Every day I check Google Play for available app updates. I'll see a notification that there are several apps with updates available... but it's never Boost... such disappointment every time. Haha!
In all honesty, I can't wait for the app to come out. Take your time, do it right. And don't do what Sync did... I'll just leave it at that.
