I had a 6-minute pitch at 1 Million Cups and wanted more than a countdown timer. I wanted to see, at a glance, how my time was breaking down across slides as I presented.

The app fills the screen with a dark-to-bright red gradient as time passes. Tapping advances slides, which steps the brightness up, creating visible bands. Wide band = you lingered. Thin band = you moved fast. If you go overtime, solid white fills from the top, overwriting your gradient.

Built it for my own pitch, but my friend already used it for a college presentation so I figured I'd share it.
