iWarm: Mobile App Concept Concept for an app that toggles on / off a highly complex mathematical loop that heats up the processor in the device to keep someone warm in the cold. Features the ability to set a timer to limit the period of warmth up to an hour. Services: Design, UI/UX Design, App Design Who hasn’t noticed their phone getting warm when you’ve had a long day of conference calls and Angry Birds? I figured – why not put that “feature” to good use. I would make a simple app that, when toggled on, would trigger a particularly complicated math loop that would get the processor going, get the phone warming, and voilà! A portable heating unit.
