Today SMS Voter has been released to the public. This is a companion application to Cocoa UltraSMS which allows you to conduct a vote using SMS messages to vote displaying the results to your laptop screen or an external display with scope for customising the display. This is provided as a universal binary and should be considered beta. Oh yes, it's free too!
I remember someone at work saying it would be cool if there was an application to allow someone to conduct a vote using SMS messages easily. So I wrote one!
You need to have a version of UltraSMS installed alongside SMS Voter. Try out Cocoa UltraSMS, if this doesn't work with your phone you might have more luck with the original UltraSMS. Please read the help before you email me!
