## What is Blockwork One?

Blockwork One turns your iPhone into a sprint start coach and race timer.

Prop your phone beside your blocks and it runs the start like a real starter: "On your marks", "Set", and a beep at a random moment so you can't guess it. It films at your phone's highest frame rate, tracks your body, and scores your set position, block push, exit angle and first steps. Then it tells you the three things to fix next.

RACE TIMING WITH TWO PHONES
Put a second phone at the finish line. The phones sync their clocks with a short audio chirp, and Blockwork times your run from the beep to your torso crossing the line, to the hundredth.

PLAN YOUR SEASON
Add meets with a goal for every event, and build workouts step by step: work, rest and repeats, so "3 × 200 m @ 90%" names itself. Log lifts, cross training and recovery with how hard they felt. The plan builder lays out your weeks around your two main events, the days you train and the equipment you have, with a taper before the big meet.

IMPORT YOUR RESULTS
Pick a screenshot of your Athletic.net or MileSplit page, or a results PDF. Blockwork reads it on your iPhone and adds your marks to your meets.

TRAIN SMARTER
• A daily check-in for sleep, soreness and energy, a training load calendar, and a warning when your training jumps too fast
• A reaction trainer to sharpen your response to the gun
• Measure your lane with AR instead of a tape measure
• 400 m pace calculator and distance training paces
• A starter-only mode for group starts and relays
• Short guides: setting your blocks, warm-up, sprint drills, staying healthy
• Progress for every event, with your bests, goals and start scores

PRIVATE BY DESIGN
Your videos and training stay on your iPhone unless you share them. No ads.
