Thank you all! I guess that's what I meant. And you're right, it depends on preferences. I was just carried away by my boredom, thinking people might be busy with something I do not know of any more. Weatherbug is a useful app, thanks.
Trip Advisor is a good one, though I'm not sure I'll be traveling soon (I really hope so).
I heard about pokemon go, but I never really tried it. I'm gonna give it a shot then.
