    Spacetime locates a contact on a map by texting them a link to click on▲89

    I find myself often texting people, "where are you?" so I wrote this little iPhone app that lets me text them a special link. When they click the link, it uses the HTML5 geolocation API to report their location and shows it on a map. http://whru.at/ It's only as accurate as the HTML5 geolocation API, but I've been finding it pretty useful. What do you think?
