AI Analysis

●●SolidBig BrainNiche Gem

Gradient bands show pacing per slide — way more useful than a boring countdown timer.

Strengths

•Visual gradient bands reveal which slides you lingered on during rehearsal.
•ImageData approach fixes mobile gradient banding at high device pixel ratios.
•Single HTML file with zero dependencies — works offline on any device.

Weaknesses

•Very niche use case — only useful for timed presentations with slides.
•No integration with PowerPoint, Keynote, or Google Slides directly.

Post Description

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.
