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.<br><br>BUILT FOR<br>• Solo sprinters who need objective practice times<br>• Track and strength coaches timing sessions on devices athletes already carry<br>• Clubs comparing a pocket lab to Freelap / Dashr / Brower-style budgets<br><br>HONEST SCOPE<br>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.<br><br>Get SpeedTrackr, wireless timing gates, jump, reaction, form, and VBT on Android.
