One next thing to do, always
An adaptive roadmap built from a student's own readiness — the weakest thing that matters most, chosen for them each day.
- Rebuilt as results change, so it never points at something already cleared
- Daily streaks with one freeze a month, and streaks require real effort
- Seventy-two badges and a milestone ladder
- Batch leaderboards with rank movement, because placement is comparative
The detail that makes it checkable
A single quick problem will not keep a streak alive — the effort bar is real.
