The Walkr app was created by Fourdesire. Once you set up an account in the Fourdesire system, the Walkr server will automatically back up all of your game data so you don't have to worry about losing your progress when you switch phones or for any other reason! Logging into you Fourdesire account also allows you to play Walkr with your friends!

We therefore strongly suggest you use a Facebook / Twitter / Weibo / Google / Email account to register your Fourdesire account (Fourdesire ID). In the future you'll be able to use your Fourdesire ID to log into Walkr and other Fourdesire apps.
