Brian Shaffer has created a mobile time tracking application using PHP, MySQL, the FreshBooks API, and Twilio's Voice API to log hours on his projects and bill customers. The app is simple to use, requiring only two calls to track work hours and notes. Brian won an iPad 2, $100 in FreshBooks credits, $100 in Twilio credits, and swag as a result of the contest. Twilio and FreshBooks regularly hold developer contests, with the current one focused on OpenVBX, an open-source virtual PBX platform, offering prizes including an Amazon Kindle 3G and $100 in Twilio credit for winning developers.
