How dual-phone sprint timing works

Place two phones

One Android phone at the start, one at the finish. A mini-tripod helps - or lean the finish phone against a bag.

Pair with a 4-digit code

The phones sync over the air so you are not relying on a thumb on a stopwatch for every rep.

Run splits and reaction

Time sprint splits (e.g. 30m / 40m) and measure sprint-start reaction off the start cue. Computer-vision finish detection marks the crossing.

Honest comparison

Phones vs laser gates vs other phone timers

People comparing options often look at Photo Finish, TrackSpeed, Metric, and hardware brands like Dashr or Freelap. Use this table as a scope check - not a slam piece. Laser systems remain the gold standard for labs and official meets.

Frequently asked questions

Phone sprint timing scope - dual-phone gates on Android, practice-grade, not FAT.

Is SpeedTrackr “timing without timing gates”?
It is phone sprint timing without laser or dedicated hardware gates. SpeedTrackr turns two Android phones into wireless start/finish timing gates for practice - so you still get gate-style splits, just not a laser kit.
How does dual-phone timing work?
Place one Android phone at the start and one at the finish, pair with a 4-digit code, and run. The phones sync for automated splits and reaction off the start cue, with computer-vision finish detection.
Can I time 30m and 40m splits?
Yes - set the phones at the distances you train (for example sprint splits such as 30m or 40m). The product is general split timing, not limited to a single fixed distance.
How does this compare to Photo Finish, TrackSpeed, or Metric?
Those apps are real alternatives people search for. Photo Finish and TrackSpeed compete on multi-phone / phone timing; Metric is strongest on phone VBT and also appears on some coach timing queries. SpeedTrackr’s wedge is Android dual-phone timing plus jump, form, reaction, VBT, and in-app coach roster/Excel in one app - practice-grade, not FAT.
Is it accurate enough vs a stopwatch or laser gates?
The site reports dual-phone timing consistency of ±0.022 seconds - more repeatable than hand timing because it removes human reaction delay. That is training consistency, not certified Fully Automatic Timing or official laser-gate accuracy.
Is SpeedTrackr Android-only?
Yes. Timing gates require two modern Android devices. An iOS version is not available. Coach roster and Excel export also live in the Android app - not a separate web coach dashboard.
Is it free?
Free to start. Premium unlocks unlimited timing sessions and AI analysis credits in-app. Check Google Play for current tiers - we do not invent prices here.
