FormMobi is a "virtual clipboard" that helps field professionals gather (and share) data on a mobile device. The app lets you record audio, take pictures, collect signatures and even create architectural sketches. You can create custom forms or rely on a library that includes forms for everything from real estate listings to construction site inspections to dairy barn feeding schedules. A cool feature is the ability to leverage GPS for all sorts of measurements, such as wooden fence estimates.
