Focus Sprint: 20-Minute Pre-Homework Exercise Primer for ADHD
An app that guides children through a 20-minute workout to boost their focus right before they start homework.
A simple app that has a child with ADHD do a guided 20-minute workout right before homework, so the demonstrated short-lived boost in focus and executive function lands exactly when they sit down to study.
Concept
A consumer app that schedules a guided 20-minute exercise primer to end right before a child with ADHD sits down to homework, revision, or an online class. The parent sets the daily "focus window"; the app cues the workout (kid-friendly video coaching at the demonstrated intensities — interval tracks, moderate-aerobic tracks, and rhythmic-movement tracks), then prompts the move to the desk inside the post-exercise window when the acute boost to executive function and sustained attention is in effect. A one-tap log (started/finished, parent-rated focus) shows families whether the primer is earning its keep week over week, so the habit survives on visible homework outcomes rather than symptom promises. It is deliberately a timing tool, not a treatment claim: it puts a demonstrated short-lived cognitive effect where it is needed, every school day.
Why now
The acute dose is now quantified. Paper [1]'s full-text digest reports that a single 20-minute bout of moderate-intensity aerobic exercise improved executive function in 8–12-year-olds with ADHD versus a video-watching control; 20 minutes of HIIT improved sustained attention in boys aged 7–15; a 30-minute rhythmic-dancing session at 60% of max heart rate improved attention; and acute benefits appear to accumulate with repetition. Paper [0]'s meta-analysis of 15 RCTs (734 children) anchors the underlying chronic signal — attention SMD −0.60 and executive function SMD 1.22 — while showing no significant effect on hyperactivity, which is why the product is scoped to attention-demanding tasks rather than sold as overall symptom control. The acute evidence comes from small single studies, which the built-in per-child outcome log is designed to match: families verify it works for their child before relying on it.

AI assessment
A highly focused, low-friction tool that converts acute clinical findings into a practical daily habit for families, though it faces significant competition from existing 'exercise prescription' concepts.
- Evidence strength 4/5
- The idea is tightly mapped to specific results from the full-text digest, particularly the 20-minute HIIT and moderate-aerobic bouts for acute executive function boosts.
- Market pull 4/5
- Parents of children with ADHD have high urgency to solve the 'homework battle,' making this a high-value, low-barrier entry point.
- Novelty & moat 2/5
- It is a variant of the 'ADHD Exercise Rx' idea; while it shifts from a 12-week clinical program to a daily consumer primer, the core mechanism (exercise dose for EF) is the same.
- Feasibility 5/5
- Building a timer-based app with video content and a simple logging system is a trivial technical lift for a small team.
- Wedge clarity 5/5
- The 'pre-homework primer' is a sharp, specific use case that targets a precise pain point in the user's daily schedule.
- Simplicity / focus 5/5
- The product avoids 'platform creep' by focusing exclusively on the timing and delivery of the exercise bout.
