The recent updates to these two apps have made what were already excellent products absolutely superb. Are they perfect? No. Google Maps is still too laggy. YouTube still has some missing features that people have been asking for and still isn’t as intuitive as it could be (the recent update has helped a lot though). But really, when it comes to enjoyable user experiences, Google is really hitting it home with these two apps. What are your favourite Google apps for Android and why?
