Codeunited has launched a new film scanner app called Helmut that lets you quickly and easily scan film onto your Android phone.
The app is currently free in Beta. It is an open source initiative that allows you to scan your film using a suitably lighted surface, and then crop and edit the resulting picture as you wish. You can digitize your old negatives, and share your lomography photos without any format or film type restrictions.
You can get the Helmut app from the Google Play store
