Straight to the point, easy to use
Ads (I'm not a fan)
Very convenient way to see where your passport allows you to go, and the visa requirements for each country.
There's also a bit of additional information for each country (eg: currency, time difference).
I think the product overall is good and has potential, I'm just a bit disappointed in ads because I really don't like them, and I think they make the interface a bit cluttered.
