Phone-camera VBT without a linear transducer

Import a video of the set, then analyze, then read the result. Not live capture. Tap the plate. Get rep speed and velocity loss without a linear transducer. Same film and tap flow for Olympic lifts, on Android and in the web app. Practice tool. Not transducer lab parity. Not form AI.

Metric and Qwik VBT often lead phone VBT roundups. SpeedTrackr's lane is phone VBT inside an Android session lab next to start/finish timing, jump, and reaction, with names on every set.

SpeedTrackr performance tools used in training

Film the set. Cut when velocity loss says so.

What you get

Session VBT from phone video

On-device processing. Olympic lifts supported on Android with the same film and tap plate flow. One free set per day on the free tier. Same Android app as start/finish timing gates, jump/RSI, and reaction.

Bar-path overlay and per-rep velocity readouts in the SpeedTrackr Android app

Mean & peak velocity

Per-rep mean concentric velocity and peak velocity from phone video after you tap the plate — the session numbers coaches actually cut sets on.

Velocity loss

Velocity-loss autoregulation from the same clip so you can decide when to stop the set without guessing.

Bar-path overlay

A shareable bar-path overlay processed on-device. No linear transducer on the bar, and the lifting clip does not leave the phone for VBT.

How it works

Film, tap, decide

Film a clean side view

Android phone, plate in frame, decent light. Pick the athlete in Coach Mode so the set lands under the right name.

Tap the plate

Trim the clip in Barbell Velocity, tap the weight plate, and let on-device video VBT read the set.

Cut or keep the set

Read mean and peak velocity and velocity loss, show the overlay, save, and move on. Coach Mode, including export, is on the web app and the Android app.

Honest vs Metric / Qwik

Android session lab — not encoder parity

Metric and Qwik often lead phone VBT roundups. Use them if that is all you need. Use SpeedTrackr when bar speed - including Olympic lifts on Android - should live next to practice start/finish timing, jump, and reaction on the phones your squad already carries.

Keep a hardware transducer when your program already depends on one. Phone VBT here is practice-grade video measurement, not encoder parity.

Who it is for

Frequently asked questions

Quotable answers about phone-camera VBT on Android - Olympic lifts, scope vs Metric/Qwik, and what this is not.

Does phone VBT work for Olympic lifts?
Yes on Android. Use the same film and tap plate flow for snatches, cleans, and related Olympic family lifts.
How does SpeedTrackr VBT compare to Metric?
Metric is a strong phone VBT option in many guides. SpeedTrackr is for coaches who want bar speed next to dual-phone start/finish timing, jump, and reaction on Android, with a roster. We do not invent accuracy percentages.
How does SpeedTrackr compare to Qwik?
Qwik and similar phone VBT apps often lead roundups. SpeedTrackr's lane is phone VBT inside an Android session lab next to start/finish timing, jump, and reaction, with names on every set. Not a claim of transducer lab parity.
Do I need a linear transducer?
Not for practice phone VBT. Keep a transducer if your program already depends on one for lab grade decisions.
Is this available on iPhone?
Native VBT is on Google Play for Android. The same film-and-tap VBT loop also runs in the browser after sign-in at speedtrackr.com/auth/login — there is no native iOS App Store app.
What do I get from a set?
Rep speed, velocity loss, and a shareable bar path overlay when you want proof in the group chat. Use it to cut a set or compare days, not as a certified lab readout.
Does VBT give sprint split times?
No. Dual-phone timing is a separate tool: practice-grade start/finish timing for one elapsed time, plus reaction off a start cue when you use that mode - never intermediate or multi-gate splits.
Is it free?
Free to start. The free VBT tier includes one set per day. Premium unlocks more in-app capacity - check Google Play or the paywall for current tiers. We do not invent dollar prices here.
