About Focus Sprint
Focus Sprint is a short web warm-up for moments when you want to switch into study mode, prepare before an exam, or check how sharp your attention feels today.
The goal is not to keep you inside the app for a long session. A round can take 20 to 80 seconds and gives you a quick record of accuracy, problem-to-answer time, current level target, and per-task online position.
If you want to use it over time, the app also includes a 4-week build-up plan: 12+ active days with short 4-minute sets. Short warm-up and repeated training are shown as separate use cases.

Important limits
- Focus Sprint is not a medical device, diagnostic test, ADHD treatment, or clinical cognitive assessment.
- Scores and target speed are internal app metrics. Top percentages come from the uploaded same-task sample. None of these guarantees better grades, exam results, or work performance.
- The app is designed as a short warm-up and record tracker, not as a replacement for long-term cognitive training protocols used in research.
- For repeated attention problems, neurological symptoms, visual changes, severe headaches, or health concerns, seek professional advice.
