“Train hard. Stay ready”
The product
A combat-conditioning round timer. Set rounds, work and rest, then train to loud audio cues — every session saved on-device with streaks and records.
The challenge
Fighters train with sweat in their eyes and gloves on their hands. C24 Cardio had to be readable at a glance, loud when it matters, and work with no account or signal.
How we built it
- Custom rounds, work and rest durations
- Loud audio cues for every transition
- Streaks, records and history — no account needed
What it proves
- Shipped to real users, not left as a prototype.
- Every state designed — empty, loading, offline and error.
- One team from first sketch to launch.
