Hey Product Hunt — I’m Dafin Edison J, a sprinter from Chennai and the maker of SpeedTrackr.
This launch is the product as it actually is today:
• Mixed-device timing gates. One device at the start, one at the finish. The second device can be Android, iPhone, or laptop. You get one elapsed practice time. Start/finish only. No intermediate splits.
• Android session lab: sprint-start reaction, jump/RSI from flight-time video, and phone VBT.
• Coach Mode: athlete roster and Excel export on the web app and the Android app.
• Web app: https://www.speedtrackr.com/auth.... There is no native App Store app. An iPhone can be the second gate. Coach Mode works on the web app and the Android app.
What it is not: not FAT or federation meet timing, not form analysis, not Timing Pro, and not a replacement for laser or beam kits.
Google Play: search SpeedTrackr (com.speedtrackr.reactionpro).
I’d like feedback from coaches who need objective practice times without a laser bag.
