Still using sync after trying… Many (too many) apps. I don’t see any ads, only the empty placeholders and they are very few. I like Sync for its fluidity and nice ui+gestures, and probably will stick to it even after those ads will become real - as I said, there’s no ad right now. Real question (no flames pls): What does Boost offers instead?
I’m actually using the in-famous 120€ app without paying a cent. And I do not see any ad. Moral: people sometimes loves to whine too much.
