Yes, playing games on the go is definitely the best way to pass the time while commuting. I often do that myself when I’m running errands. As for the app, you can easily download the full-featured Yay android app. It runs smoothly without any lag. Like, the important thing is to download it only from the official source, either the Google Play Store or the official website. There are plenty of fake copies out there. The app is user-friendly and saves all your progress. Oh, and it also sends notifications about new free coins and syncs fully with your account. Are you planning on not using your laptop at all?
