🏃♂️ 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 it blends my passion for sprinting with AI and coding.
💡 What Is SpeedTrackr?
SpeedTrackr is an Android sports-performance app for athletes and coaches. It is not a web app, not an iOS app, and not a remote-coaching SaaS. Same app, on the track:
- 🎯 Dual-phone wireless timing gates — pair two Androids with a 4-digit code for practice start/finish timing over a set distance
- ⬆️ Jump / RSI from flight-time video
- ⚡ Reaction starts off a start cue
- 🏋️ Video-based VBT (on-device bar velocity)
- 📋 Coach roster + Excel export — inside the Android app only
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-phone timing is more consistent than a hand stopwatch for training. Stated consistency is ±0.022s versus hand timing — practice-grade, not competition FAT.
It is not: official photo-finish or certified laser gates. Not a web coach dashboard. Not a periodization planner, wellness OS, or API-licensing platform. Coach support today is roster management and Excel export in the Android app — that’s it.
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
The product athletes use is the Android app. This website is the marketing and education layer (Next.js). Early experiments lived on the web; the timing protocol, jump, reaction, and VBT all shipped where training actually happens — on two phones at the track.
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/finish times and form feedback 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 making the Android app better at the job it already has: tighter timing, clearer form cues, and coach roster / Excel that stay honest — not a web dashboard, 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.
