Graham Christensen, a developer at Clarify.io, created an app using Twilio's API and Clarify.io that helps him track what's in his moving boxes by labeling each box with a number and recording a voice message of its contents. The app uses Twilio SMS to send the box number when Graham needs to find something specific, allowing him to quickly locate it. The system consists of four scripts: start.php, gather.php, save.php, and search.php, which work together to receive incoming calls, record audio, process recordings, and respond with results from Clarify.io's API. This app simplifies the moving process by reducing anxiety and making it easier to find specific items, as Graham found in his own experience using it for a recent move.
