About

Coach Larry Stroke Lab

Features
Read full description

Coach Larry Stroke Lab helps swimmers and parents turn focused swim clips into technical feedback, practice priorities, and same-angle recheck plans. The app opens directly into a mobile stroke review workflow: choose a stroke and camera angle, record the swimmer's goal, route a secure video link or clip manifest, and keep family-ready review notes and practice assignments organized. For swimmers and parents: - Submit a swim clip or secure video link with stroke, camera angle, package, guardian consent, and privacy preferences. - Review coach feedback previews, timestamp markers, action plans, and recheck capture guidance. - Sign in to keep private review drafts, notes, and Larry-assigned practice work tied to the swimmer account. For Coach Larry's workflow: - Track booking leads, review readiness, coach notes, practice assignments, call notes, video edit plans, and delivery status. - Keep public profile, package, privacy, and release-readiness copy in one operating console. - Use read-only admin previews without exposing private coach queues until a coach or admin account is authorized. Coach Larry Stroke Lab is built for private swim video review and practice planning. Review material is kept private, parent or guardian consent is explicit, and direct video upload remains limited until the prepared Firebase Storage workflow is fully enabled.
