Web app and iOS apps are in the works:-)
On minor difficulty with a web app, is continuously polling a person's location to find the closest power points to them, but we should have this fixed in the next few days!
Overall it was a matter of getting this out the door ASAP to be helpful as possible as fast as possible, and then iterating better and better versions.

We released an app to map out every power socket in every airport in the world. Ambitious? Sure. Feasible? Definitely. If you're travelling, check this out. We still need help finding power sockets — if you see one at an airport, it's very easy to submit it for everyone to see, right from the app. Join us, help us out!
