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.
4.99 without a coupon, but there's always a coupon. Last time I had one I paid one Euro.
So this license is 22 Big Macs, or 110 Big Macs with coupons.
