About this app
Turn two Android phones into wireless timing gates, plus jump, reaction, AI form, and video VBT in one app.
SpeedTrackr is an Android sports-performance app for sprinters, track coaches, and S&C athletes who need practice-grade data without laser hardware.
WHAT YOU GET
• Dual-phone wireless timing gates, pair two Androids with a 4-digit code for practice splits (e.g. 30m / 40m), Normal and Reaction Start
• Sprint-start reaction — audio countdown, false-start detection, camera wrist detection for solo block work
• Vertical jump / RSI — phone-video flight time; no jump mat or force plate
• AI sprint form — Ground Contact Time, stride cues, joint angles, and drill suggestions from your clip
• Video VBT — mean/peak velocity, velocity loss, ROM, bar path from lifting video (no transducers)
• Coach tools in-app — athlete roster management and Excel export (Android app only)
WHY PHONE GATES
Laser kits cost hundreds to thousands. SpeedTrackr uses phones you already own. Dual-phone timing consistency of ±0.022s — more repeatable than a hand stopwatch because it removes human reaction delay. Practice-grade for training — not official Fully Automatic Timing (FAT) or certified laser systems.
BUILT FOR
• Solo sprinters who need objective practice times
• Track and strength coaches timing sessions on devices athletes already carry
• Clubs comparing a pocket lab to Freelap / Dashr / Brower-style budgets
HONEST SCOPE
Android only (requires Android 10+). Not a web coach dashboard or coach OS. Not competition FAT. In-app purchases unlock premium analysis and sessions, free to start.

What’s new
- Coach Mode landed yesterday. Tonight is a tiny finish-gate polish. Two updates in two days, we owe you a quieter week.
- The finish camera now picks up a slightly thinner crossing. Same 90 cm setup. Same confirm step if a time looks unsure.
- That is the whole note. Go time someone.
