What This Means for Your Strategy
You Need Phone-First Thinking
Don’t build a web app and then “make it work on phone.” Build FOR the phone from day 1. Camera, touch, voice, sensors – these are your primary inputs.
Device Data is 25% of Your Score
HackTracker measures actual phone usage and Office Kit usage. You can’t fake this in your pitch. Either you used the phone creatively, or you didn’t.
Office Kit is Your Superpower
Screen mirror, shared clipboard, file transfer, remote control. During Red Light, your laptop is CLOSED as a build machine – Office Kit is the only bridge. Master it before the event.
Smaller Teams = More Ownership
Max 3 people. Everyone needs to contribute. No passengers. This is intense.
How to Prepare
- Download Office Kit (pc.vivoglobal.com) and practice the workflow
- Research on-device AI models (Phi-3, Gemma 2B, Whisper Tiny)
- Build one small app that uses camera + AI on a phone
- Plan your Red Light vs Green Light work split
- Pick your track and prepare your idea screening submission
