British agency Future Platforms has been trying to foster ethical ticket-swaps with its Twickets service. Now there’s an app for that. The idea: a fan-to-fan ticket exchange where people can shift their unwanted spares, but where they’re not allowed to sell them for more than face value. The app can be used to buy or sell tickets, and supports music as well as football, comedy and theatre events. “Essentially we are committed to helping ensure empty seats are filled, without having to utilise expensive secondary ticketing channels which are increasingly ripping off fans,” explains its App Store listing. Twickets launched in November 2011 on social networks, and now has more than 30k Twitter followers, with nearly 45k tickets having been swapped in the last year. Future Platforms says an Android version of the app will be released soon, as well as a mobile website.
