XRespond is a virtual device lab for designing, developing and testing responsive websites. The idea is simple: It enables you to make website comparisons side by side, as if you had different devices on the wall in front of you.
It's worth pushing the team and educating them about this app! Spond is super easy to get used to and once everybody is on it, there are only pros for all the parts–me (the coach), the players AND their parents.
