Your climb
7 days to WalkStreaks earn tiers, freezes, and Sparks, never the next lesson. One lesson a day banks the streak.
🏆 August challenge
0/20 tasksHow Flint works ›
🔥 Streak — one lesson a day banks it. That's the whole game; extra lessons bank tasks, not days.
❄️ Freezes — earned at day 3 and day 14. A freeze covers a missed day automatically, so life doesn't burn your streak.
⚡ Sparks — every 7-day streak earns one: a pass that opens any Pro lesson, yours forever. Bank up to 2.
🏔 Tiers — Crawl → Walk (day 7) → Run (day 30). Tiers open capability and status — never the next lesson.
📈 Levels — high scores raise your level; higher levels hide the examples and raise the pass bar. The training wheels come off as you get good.
🎯 Free plan — 2 lessons a day. The streak only ever needs 1.
