On iPhone

No App Store download needed. Open it in Safari and start timing.

There is no iOS app yet, and we would rather say so than let you find out at the download button. The web app runs the same ported engines in your browser — on an iPhone, an iPad, or any laptop.

Timing Gate

Two phones, one on each line. The same detector and the same clock sync the Android app uses — and the second phone can be an Android, an iPhone or a laptop.

Jump Measure

Film in your camera app's slo-mo, import the clip, mark takeoff and landing. Height, hang time and reactive strength, worked out on your device.

Barbell Velocity

Upload a set, tap the plate, get mean and peak velocity per rep. No extra hardware, nothing to strap to the bar.

Add it to your Home Screen from Safari's share menu and it opens full-screen, like any other app. Your account and history are the same ones the Android app uses.

Who it's for

Built for athletes who test themselves and coaches who test a squad.

For athletes

Know your numbers. Beat them next session.

Sprinters, lifters, jumpers and team-sport players use SpeedTrackr to test alone, with nothing but a phone and a tripod or a water bottle to lean it on.

  • Your best in every test, on Home

    Sprint, bar speed, jump and reaction records with the date you set them, and a NEW tag for a best in the last week.

  • Bar speed for every rep

    Film a set and get m/s per rep: mean velocity for strength lifts, peak for Olympic lifts, and velocity loss across the set.

  • Beat your last time at the same weight

    The first set at a new load becomes the baseline. Next time, History shows the gap: faster or slower than last time.

  • Share videos with live numbers

    Bar path and bar speed counting up on the video, ready for a story or for your coach.

Timing Gates

Two devices become synchronized start and finish gates for a 20 m, 30 m or any distance you set. The second device can be Android, iPhone, or a laptop. Start and finish times only, no splits, and the app reminds you to move the finish device when you change the distance.

  • Synchronized start & finish gates
  • Automated start/finish timing
  • Reaction time off the start cue
  • Computer-vision finish detection

VBT — Bar Velocity

Film a set and get bar speed for every rep in m/s: mean velocity for strength lifts, peak velocity for Olympic lifts, and velocity loss across the set. The first set at a new weight becomes the baseline to beat, and the share video shows bar speed counting up live. Processing happens on your phone.

  • Mean velocity per rep (strength lifts)
  • Peak velocity per rep (Olympic lifts)
  • Velocity loss across the set
  • Share video with live bar speed

Independent research (Renner et al. 2024, PLOS ONE) found video-import bar tracking the most accurate smartphone approach to VBT. That's the category this tool belongs to — the study didn't test SpeedTrackr.

Why SpeedTrackr

One phone app instead of a bag of testing kit.

Practice-grade testing for every session, not certified competition timing. Here is what that gets you.

01

Four tests, one app

Sprint timing, bar speed, jump/RSI and reaction share one history and one athlete list. Other phone apps usually cover one of these, so you end up running four.

02

No hardware to buy

The phones you already have replace laser gates, a jump mat, a reaction light and a bar sensor. Nothing to charge, carry or strap to the bar.

03

Made for testing a squad

Pick who's up before each test, keep each athlete's body weight, and see every athlete's records and new bests without opening a spreadsheet.

04

Numbers a coach can act on

Mean velocity for strength lifts and peak for Olympic lifts, velocity loss across the set, and a straight comparison with the last set at the same weight.

05

Your data goes where you need it

Export any history to Excel. Your account and results are the same on the Android app and the web app.

06

Built by a sprinter

Made by a sprinter who trains with it and answers the Play Store reviews. Updates ship often, and most of them start as an athlete's request.

Process

Enjoyable, precise timing every time.

Place & Connect

Position one device at the start line and one on a tripod at the finish. The second device can be Android, iPhone, or a laptop. Pair them instantly with a simple 4-digit code.

Auto-Sync Clocks

The devices automatically synchronize their internal clocks over the air, dramatically more consistent than a hand-timed stopwatch.

Run & Time

Sprint through. The start device listens for your starting cue and the finish gate detects your crossing with computer vision, calculating your run time instantly.

Cost-effective measurement

Pro-grade timing, zero hardware debt.

Ditch the heavy tripods and expensive proprietary sensors. You likely already own the hardware you need.

Origin

“I wanted real numbers instead of a human thumb on a stopwatch.”

After 14 years of competitive sprinting in Chennai, the difference between a good day and a bad day came down to hundredths of a second — but real biomechanical feedback meant expensive labs and elite specialists I never had access to.

So I built SpeedTrackr: honest measurement from the processing power already in our pockets. Now I'm using it on myself, publicly — a 52-week program with every session logged and every time trial published.

Frequently asked questions

Everything you need to know about setting up and trusting the system.

What is SpeedTrackr?
SpeedTrackr is a sports performance app for coaches and athletes. Two devices become start and finish timing gates (the second can be Android, iPhone, or a laptop), a video of your set gives bar speed per rep (VBT), a jump clip gives jump height and RSI, and a reaction test times your response to the start signal. Coaches get Coach Mode: a Squad tab with every athlete's records and new bests, and Excel export. Android app on Google Play; iPhone users use the web app at speedtrackr.com. Built by sprinter Dafin Edison. Free to start.
How does the two-phone timing setup work?
Place one device at the start and one at the finish (a mini-tripod helps, or lean the finish device against a bag). The second device can be Android, iPhone, or a laptop. Pair them with a simple 4-digit code. The devices sync over the air so start/finish timing and reaction off the start cue are automated instead of relying on a thumb on a stopwatch. Computer-vision finish detection helps mark the finish.
Is SpeedTrackr Android-only?
The native app is Android (Google Play). A web app is also live so iOS and desktop users can sign in at speedtrackr.com and train in the browser. For dual-device timing gates, the second device can be Android, iPhone, or a laptop. There is no native iOS App Store app yet.
Can I use SpeedTrackr on iPhone?
Yes through the web app in your browser. Sign in at https://www.speedtrackr.com/auth/login. There is no native iOS App Store app yet. For timing gates, your iPhone (or a laptop) can be the second device alongside another phone.
How accurate is it compared to a stopwatch, laser gates, or FAT?
SpeedTrackr is practice-grade timing. Because the phones detect the start and the finish, it removes the thumb-on-a-stopwatch delay that makes hand times inconsistent. It is not certified Fully Automatic Timing (FAT) and not a replacement for laser or photo-finish systems at sanctioned meets. Use it to track training progress; use certified systems for official results.
Is SpeedTrackr free? What's included?
SpeedTrackr is free to start. Premium unlocks extra timing sessions inside the app. The free VBT tier includes one set per day, with on-device processing. Check Google Play or the app for current paid tiers and which coach features are included.
Does my VBT video leave my phone?
For VBT, SpeedTrackr processes video on-device so your lifting clip does not leave the phone.
Who is SpeedTrackr for?
Strength and conditioning coaches, sprint and track coaches, weightlifting coaches, team-sport coaches who test many athletes, and athletes who test themselves: sprinters, lifters, jumpers and field-sport players who want speed, power and bar-speed numbers without a lab.
How does SpeedTrackr compare to dedicated timing, jump, or VBT hardware?
Lasers, photo-finish systems, force plates, and linear transducers remain the gold standard for labs and official meets. SpeedTrackr consolidates training tools onto phones and laptops you already own. It is a pocket lab for practice, not a certified competition timer.
Is there an iOS version or web coach dashboard?
There is no native iOS App Store app. iPhone users sign in to the web app at https://www.speedtrackr.com/auth/login and use timing, jump and bar velocity tools in the browser. Coach Mode (Squad tab, athlete pages, new bests) is in the Android app for now.
How does vertical jump and RSI measurement work?
Film the jump, then step through the clip frame by frame and mark takeoff and landing. SpeedTrackr works out jump height from flight time; drop jumps and hops also give RSI (reactive strength index). Normal 60 fps video works and slow motion is the most precise. With the athlete's body weight saved, you also get jump power. No jump mat required.
What does SpeedTrackr's video VBT measure?
Film a set and get bar speed for every rep in m/s: mean velocity for strength lifts, peak velocity for Olympic lifts, and velocity loss across the set. The first set at a new weight is shown as the baseline to beat, and History compares each set with the last one at the same weight. The share video shows the bar path with bar speed counting up live. No sensor on the bar. The free tier includes one set per day.
How does reaction and start timing work?
SpeedTrackr measures reaction timing off a start cue so you can train and trend sprint-start reaction without a separate reaction-timer box. Use it for practice starts and session logs, not as an official starter-system FAT replacement.
What can coaches do in SpeedTrackr?
Turn on Coach Mode in Profile in the Android app. The Squad tab lists every athlete with when they last tested, how many results they have and a NEW BEST tag when they beat an earlier result. Each athlete has one page with Records, Progress and every Result. Coach Home flags who set a new best in the last 7 days (a first result is a baseline, never a new best). Body weight is saved per athlete so jump power is right for everyone. Add athletes in the Squad tab or by typing a name when saving a result, and export any history to Excel.
What hardware do I need for SpeedTrackr?
Two devices for timing gates: the second can be Android, iPhone, or a laptop. A cheap mini-tripod helps hold the finish device steady, but many athletes lean it against a water bottle or bag. No laser gates or external VBT sensors are required.
