Knowing the method is not the same as being ready to use it.
- Correct answers that take too long.
- Small arithmetic slips that derail harder questions.
- Practice that feels busy but does not show what has been retained.
How Daily Sharpen works
- Practise briefly. Complete one focused session.
- Correct properly. Re-enter missed answers and meet a related question later.
- Build evidence. The programme distinguishes learning, accuracy, fluency and later retention.
The free challenge
7 free sessions, at most one per day, open for 10 days. Questions adjust to your answers as you go. At the end you see a result built from what you actually showed: what improved, what held up, and what is worth developing.
The challenge is once per learner. It is not a subscription trial and does not need a card.
What paid access adds
- Choose what you are working towards.
- A focused diagnostic that reuses your challenge evidence.
- Worked lessons and targeted correction.
- A personalised Daily Sharpen each day.
- Weekly checks that improvement is being retained.
Evidence, not just points
Every skill moves through four stages: learned with support → independently accurate → fluent at target pace → retained. Speed only counts alongside correctness, and correcting a mistake in the moment is not treated as mastery until a later check confirms it stuck.
For parents
- Calm, age-appropriate design with private progress by default.
- No advertising built from learning data.
- Clear renewal and cancellation.
- Evidence of named skills, not only streaks.
