What are we looking for?

We’re looking for Thrutu buttons that demonstrate imaginative ways of enhancing the phone call, or give people new reasons to call each other. The winning entry could be a game that keeps callers entertained, or a utility that makes life simpler. It could make us laugh or it could impress us with its brilliant design.

When we judge the entries, we’ll be considering the following criteria:

  • Is it fun or useful?
  • Is it attractive to use?
  • Does it work well, as described and without bugs?
  • Does it make us want to call our friends to use the button with them?

In this contest you can enter native Android buttons or cross-platform web buttons. All the buttons will be judged together (there are no separate prizes for native / web buttons).

How to enter

Once you’ve built your button, log in to your Thrutu Developer account and publish it to Thrutu Central through the My Buttons page.  (If it’s a native Android button, publish it on the Android Market too.)  Then all you need to do to enter the competition is complete this simple submission form.

Entries must be submitted by 11:59pm Pacific Time on 30th September 2011 16 October 2011.  We’ll be announcing the winners in October 2011, when we’ll also contact prize-winners by email.

Who can enter

You’ll find full eligibility details in the contest rules, but if you’re over the age of legal majority and if this contest is permitted where you live, you’re likely to be fine to enter. There are a few countries from which we can’t accept entries, and Metaswitch employees and their immediate family are also not eligible for this contest.

Here are our full contest rules including eligibility requirements and contact details.  Good luck!
