Hailo has been something of an overnight success since its launch towards the end of 2011. The idea was so simple, but truly a way in which Londoners could use their Android devices in actual, real world, day-to-day situations. By making a sometimes unpleasant experience -- trying to flag down a cab -- and getting your Android device to do the work. Anyone in London for the Olympics, seriously, download a copy of this app while you're there.
Today the Hailo team marks another milestone since the launch of the service, in their first expansion outside of London. The second city to go live, is the Irish capital, Dublin. This is fantastic news, and hopefully the start of a bright, and widespread future for the service. There's a whole lot of cities around the world that could benefit from something as useful as this.
