MOSAIC
A physical-education record system for teachers and students aged 12 to 14. It records what a student can actually do and what to teach next — and deliberately refuses to produce a rank, a leaderboard, or a single fitness score.

Most of this product is defined by what it refuses to do.
Measuring children is easy to get wrong. A number that ranks a twelve-year-old against their class is worse than no number at all, so the hard part was deciding what never to build.
Fitness apps rank children against each other
No class rank, no leaderboard, no overall fitness score. The record is per-skill and private to the student.
Phones in a PE lesson are a distraction and a privacy problem
The lesson runs on printed session cards. Results are entered afterwards, so no child needs a device.
A score tells a teacher nothing about what to do next
Each record resolves to a specific next task, so the teacher knows what to teach on Monday.
Student data crossing borders is a legal risk for schools
Each school holds its own data under its own country’s rules.
What it runs on.
What it still can't do.
- Authentication is not finished. The sign-in flow exists in the interface but is not yet enforced end to end, so the platform is not ready for real student data.
- The Android app is behind the web version and does not yet cover every screen.
