About

SprintLab is a pocket performance lab for sprinters — track & field athletes, masters sprinters, and the coaches who train them. Log your bests, track training, and let SprintLab turn your data into a daily readiness call and real performance insights. Everything lives on your device. PERFORMANCE READINESS • A 0-100 readiness score each day, with a clear call: Sprint, Gym, Recovery or Rest • Blends sleep, recovery, HRV, resting heart rate, body temperature and stress with your own energy, motivation and leg-freshness check-in • Every value is editable by hand and labelled by source (Manual, Oura, Calculated, Estimated) • Insights like "Today matches your previous personal-best days" and "HRV is 12% above your monthly average" PERFORMANCE ANALYTICS • Automatically finds the relationships that matter: sleep vs 100m time, HRV vs top speed, stress vs performance, gym load vs speed and more • Correlations, trends, and the recovery conditions your personal bests actually happen in • Gets sharper the more you log — the analysis grows with your data WEARABLE & HEALTH SYNC (OPTIONAL) • Connect an Oura Ring to auto-fill sleep, recovery, HRV, resting heart rate, temperature and stress • Or sync Apple Health to pull sleep, resting heart rate, HRV, respiratory rate and blood oxygen — read on your device, no account needed • Sign-in uses each vendor's official, secure flow; Apple Health is read on-device with your permission — SprintLab never sees a password • Health data is stored on your device; disconnect any time • Not required — the whole app works with manual entry alone PERSONAL BEST TRACKER • PBs by distance from 30m to 400m and custom distances • Electronic and hand timing kept separate; a hand time never overwrites an electronic record • Wind readings with automatic wind-legality flags (over +2.0 m/s is marked wind-aided, never a legal PB) • Block, standing and flying starts tracked separately • PB celebrations that tell you exactly which time you beat TRAINING DASHBOARD • Log sessions in seconds: type, timed reps, gym work, notes, injuries, sleep • Progress graphs per distance and improving/declining trends • A training consistency score that rewards showing up, week after week TOOLS • Sprint calculator: speeds (m/s, km/h, mph), equal-speed equivalents and even-pace splits • WMA-style age grading for masters athletes, fully offline ON-DEVICE INTELLIGENCE (OPTIONAL) • Turn on Apple Intelligence to have your insights and daily briefing written by Apple's on-device model — processed entirely on your iPhone • Nothing leaves your device; no account, no cloud • Needs a compatible iPhone with Apple Intelligence; otherwise the built-in engine writes them — either way the app works the same • Off by default PRIVATE BY DESIGN • Your data is stored on your device • No account, ever • Full backup export and import you control • Delete everything in two taps Built with dark mode, VoiceOver and Dynamic Type throughout. Whether you're chasing a school record, a masters title, or your first sub-13 100m, SprintLab keeps the numbers straight so you can focus on running fast.
