Real-life mobile gestures for app mockups

Device emulators for mockups
Simulate your mobile mockup on desktop screens, or test it out on real devices like smartphones and tablets to get important feedback from users and stakeholders.
Justinmind allowed us to get the design right and then fit the technology around the experience, not the other way around.
