## What is SprintLab?

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.
