🏃♂️ From Sprinter to Developer
For years, I’ve been chasing faster times on the track — and learning the hard way that there aren’t many affordable tools to help sprinters like me time practice runs or keep a simple athlete roster without buying laser gates or a lab.
So I decided to build one. On Android. On the phones athletes already carry.
🎥 Watch: Why I Built SpeedTrackr
In this video, I explain the why behind SpeedTrackr, and how sprinting led me to build a practice timing app.
💡 What Is SpeedTrackr?
SpeedTrackr is an Android-first sports-performance app for athletes and coaches, with a web app for iPhone and laptop users (no native App Store app). Not a remote-coaching SaaS. Same account, on the track:
- 🎯 Dual-device wireless timing gates: pair start and finish with a 4-digit code for practice start/finish timing; the second device can be Android, iPhone, or a laptop
- ⬆️ Jump / RSI from flight-time video
- ⚡ Reaction starts off a start cue
- 🏋️ Video-based VBT (on-device bar velocity)
- 📋 Coach Mode on the web app and the Android app: roster and Excel export
Free to start. Get it on Google Play.
Built by a sprinter, for sprinters — no laser hardware and no six-figure sports-tech budget required.
What it is — and what it isn’t
It is: a pocket performance lab for practice. Dual-device timing is more consistent than a hand stopwatch for training. Practice-grade, not official timing.
It is not: official photo-finish, certified laser gates, intermediate splits, or form analysis. Not a periodization planner, wellness OS, or API-licensing platform. Coach Mode is roster and Excel export on the web app and the Android app.
If you want the honest product snapshot, start at speedtrackr.com or the free-tools hub.
🔍 The Problem I Wanted to Solve
- No cheap way to time practice runs without a partner holding a watch or buying gates
- Training notes scattered across WhatsApp, spreadsheets, and memory
- “Coach platforms” that promised remote SaaS and never helped on the track
👨💻 How I Built It
Athletes use the Android app and the web app (no native iOS App Store app). This website is also the marketing layer. Timing, jump, reaction, VBT, and Coach Mode run where training happens: on a phone or a laptop at the track. The second timing device can be Android, iPhone, or a laptop.
I still write about the stack because the story matters: computer vision, a pairing code between devices, and a refusal to pretend a browser tab can replace a start/finish gate.
🌍 Who This Is For
- 🏃 Solo sprinters who need start and finish times without a timing crew
- 📈 Coaches who want in-session Android tools plus a simple roster and Excel export
- 💡 Athletes who want practice-grade numbers, not a certified meet system
📈 What’s Next?
I’m focused on the job the app already has: tighter practice start and finish timing, and Coach Mode on the web and Android that stays honest. Not form analysis, not smart periodization-as-a-product, not API licensing.
If something new ships, it will be in the Play Store listing and on this site. I will not preview features that don’t exist.
