Twickets is a fan-to-fan ticket exchange, designed to help concert goers buy and sell spare tickets to any event in the UK.
Users of the service can offer their spare tickers for sale through the Twickets app or by tweeting the details to @Twickets.
The deal is then advertised to their large audience of more than 100,000 followers, allowing them to buy the tickets using the app, with tickets being exchanged directly.
The service is currently iOS and Android-only, but they just tweeted that a Windows Phone app is also on the way.
Unfortunately this is the second time now that they have promised a Windows phone app, the last being in October last year, so we suggest its about time they start delivering on their promise.
