Whether you’re letting your upper lip get fuzzy for a good cause or just decided you want to rock a 70’s fashion trend, there is now an app that will let you track your progress and even make a mini-movie.

Once upon a time ago, some intelligent guy decided he wanted to quit shaving, and to make sure he didn’t rock the boat with anyone when his face started getting furry, he said he was doing it for a good cause, and he even used the Movember Mobile App for iPhone and Android to make the process seem more formal and organized. Thus was born Movember (this origin story is technically untrue).

Mustaches and November have transformed growing facial hair into a social event, complete with photo-sharing, mustache-growing journals, and a sense of brotherly camaraderie that isn’t even experienced during football season. With the Movember app, you can track your mustache progress, share updates with others, and even have your photos stitched together to create a stop-motion movie that will show the evolution of your mustache through the month.

The app works with both iPhone and Android, and it’s completely free, so what are you waiting for? Your mustache to send you an invitation?
