Algebra to calculus. One small step a day.
We pick the lesson with the lowest mastery — no decision fatigue.
Wrong answers always get a clear, numbered solution. Never just "Not quite."
Questions you stumble on resurface 1 day, 3 days, 1 week, 2 weeks, 1 month later.
Personal momentum. No leaderboards, no social pressure. Streak freezes auto-spend if you skip.
