Phone-Camera VBT on Android (No Transducer)

Velocity based training should not require a cable on the bar for every small squad session. SpeedTrackr Barbell Velocity is phone camera VBT on Android: film the set, tap the plate, get rep speed and velocity loss you can act on, with a bar path overlay worth sharing.

This page is for coaches comparing phone VBT options. Android only. Practice tool, not a claim of encoder lab parity.

Start in the app via Google Play.

What it is

• Video / phone VBT on Android
• Session useful numbers: rep speed, velocity loss, and estimated 1RM when the app shows them
• Bar path overlay as the share asset
• Coach Mode so the set is saved under the athlete who lifted (roster + Excel export in app)

What it is not

• Not a claim of encoder parity with Metric, Vitruve, GymAware, or other cable / transducer systems
• Not an iPhone product
• Not a web coach OS, periodization suite, or remote SaaS dashboard
• Not timing gates, and not intermediate split timing of any kind

Timing in SpeedTrackr is a separate tool: two phones as start and finish gates for one practice grade elapsed time, plus reaction off a start cue when you use that mode.

Honest framing vs Metric / Qwik

Metric and similar apps often win “best VBT app” roundups, especially where iPhone is assumed. SpeedTrackr’s lane is different:

• Android session lab: VBT next to start/finish timing, reaction, jump, and sprint form
• Names on the set via Coach Mode
• The demo is the free session itself, not a feature list

Use phone VBT for practice decisions (cut the set, compare days). Keep a hardware encoder when your program already depends on one.

How coaches use it

1. Pick the athlete in Coach Mode
2. Film a clean side view of the bar / plate
3. Tap the plate in Barbell Velocity
4. Read rep speed and velocity loss. Show the overlay. Decide the next set
5. Save and move on

If the clip is dark, cropped, or the plate leaves frame, fix the recording before arguing with the number.

FAQ

Do I need a linear transducer?

No. This path is phone camera VBT on Android.

Is it as accurate as a cable encoder?

Do not treat it as encoder parity. It is practice grade video VBT for training decisions.

Can I track a squad?

Yes, with Coach Mode: names on tests, Home and History per athlete, Excel export in app. There is no separate web coach dashboard.

Does this give sprint split times?

No. Dual phone timing is start to finish only. VBT is a separate tool.

Where do I start?

Google Play: SpeedTrackr. Related timing context: phone sprint timing vs laser gates.

Film the set. Cut when velocity loss says so. Keep the name on the file.
