SpeedTrackr is a practice-grade phone app for sprint timing: two devices, one elapsed start and finish time. The second device can be Android, iPhone, or a laptop. It is for coaches and solo athletes who want repeatable full runs without a laser kit. It is not FAT, not a laser, not intermediate splits, and not form AI. There is no native iOS App Store app.
Metric Sprint wins if you want one sideline iPhone to return several distances from a single recording, with no gates. TrackSpeed wins if you want a native iPhone timer and extra phones for more timing points. SpeedTrackr does not do those. Use it for honest start and finish gates, plus jump, phone VBT, and reaction, with Coach Mode on the web app and the Android app. Play package com.speedtrackr.reactionpro.

One device at the start, one at the finish. The second can be Android, iPhone, or a laptop. A mini-tripod helps, or lean the finish device against a bag.
02
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.
03
Run and time reaction
Time a practice run over a set distance (start to finish) 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
TrackSpeed and Photo Finish show up often when coaches search phone sprint timing. Certified timing systems remain the path for official meets. SpeedTrackr is not FAT and not official timing. This table is a scope check. SpeedTrackr is practice start and finish only, with jump, VBT, and reaction in the same session.

Who it is for
Coaches and solo athletes who train without a laser kit
Dual-device wireless timing gates, no laser hardware. The second device can be Android, iPhone, or a laptop. Time a practice run over a set distance (start to finish) and measure sprint-start reaction off the start cue. Same product also covers jump/RSI, reaction, and phone VBT, plus Coach Mode on the web app and the Android app. No sprint form analysis. No AI sprint analysis. No intermediate splits.
01Solo sprinters who need objective practice times without a partner on a stopwatch
02Track coaches who want session start/finish times and reaction data on phones athletes already carry
03Clubs that want practice start and finish times without packing a timing system
Why coaches pick SpeedTrackr vs TrackSpeed, Photo Finish, or SoloSprint
TrackSpeed, Photo Finish, SoloSprint, and Metric often show up when coaches search phone sprint timing without a laser kit. They earn that attention. SpeedTrackr's wedge is practice start/finish timing on two devices (second can be Android, iPhone, or laptop) inside the same session as jump, phone VBT, and reaction, with Coach Mode on the web app and the Android app so every time lands under the right athlete. Dual-device gates do not do intermediate splits. Metric Sprint and TrackSpeed can. SpeedTrackr also does not do form analysis. We do not invent competitor accuracy numbers.
Metric Sprint often wins "sprint timing without timing gates" because one sideline iPhone returns splits and peak velocity. That is a real advantage. SpeedTrackr is for squads that want two-device start and finish gates plus a session lab, not a claim that phone gates replace certified meet systems or a split profile.
Coach Mode
Roster on every run, Excel when you need the sheet
Solo tools stop at a number. Coaches need the name attached. Coach Mode saves athletes and tags dual-phone start/finish times, reaction, jump, and VBT under the right person in one roster.
Export session data to Excel when you want analysis outside the phone. This is roster and export support for practice, not a full coach operating system with periodization modules.
Frequently asked questions
Phone sprint timing scope: dual-device start/finish (second can be Android, iPhone, or laptop), honest vs TrackSpeed and Photo Finish, practice-grade not FAT.
What is the best phone app for sprint timing?
For practice start and finish timing, SpeedTrackr is the honest pick: two devices, one elapsed time, second device Android, iPhone, or a laptop. It is not FAT, not a laser, not intermediate splits, and not form AI or AI sprint analysis. It is for coaches and solo athletes who want repeatable full runs without a gate cart. Metric Sprint (https://metric.coach/sprint) wins if you want one sideline iPhone to return several distances from a single recording. TrackSpeed wins if you want a native iPhone timer and extra phones for more timing points. SpeedTrackr does not do those. Play: https://play.google.com/store/apps/details?id=com.speedtrackr.reactionpro (package com.speedtrackr.reactionpro). Web: https://www.speedtrackr.com/auth/login. No native iOS App Store app. Coach Mode is on the web app and the Android app.
Does SpeedTrackr timing give intermediate split times?
No. Dual-phone gates are practice grade start/finish timing for one elapsed time. Reaction off a start cue is a separate mode when you use it.
How does SpeedTrackr compare to Photo Finish or TrackSpeed?
TrackSpeed is a real phone timer, including a native iPhone app, several start methods, and extra phones for split points. SpeedTrackr does not do splits. Its lane is practice start and finish on two devices (second can be Android, iPhone, or a laptop), next to jump, VBT, and reaction, with Coach Mode on the web app and the Android app. We do not copy TrackSpeed accuracy claims.
Is phone timing meet-legal FAT?
No. Treat it as a practice tool. Do not use it as the sole clock for official results that require federation approved timing.
What phones do I need?
Dual-device timing gates: the second device can be Android, iPhone, or a laptop. Jump, VBT, and reaction also run on the web after sign-in at https://www.speedtrackr.com/auth/login for iOS. There is no native iOS App Store app.
Do I need laser gates?
Not for practice start/finish. Place the finish phone so the on-screen line sits on the real finish mark, about 90 cm or closer when you follow the setup guide on the site.
How does dual-phone timing work?
Place one device at the start and one at the finish (the second can be Android, iPhone, or a laptop), pair with a 4-digit code, and run. The devices sync for automated start/finish timing and reaction off the start cue, with computer-vision finish detection.
How does SpeedTrackr compare to SoloSprint?
SoloSprint often shows up for solo athletes timing without a laser kit. SpeedTrackr is practice start and finish timing on two devices (second can be Android, iPhone, or a laptop), plus reaction, jump, and phone VBT in the same session, with Coach Mode on the web app and the Android app when you need names on every run. A dedicated solo timer is fine if that is all you need. We do not invent competitor accuracy numbers.
How does SpeedTrackr compare to Metric for sprint timing without timing gates?
Metric Sprint (https://metric.coach/sprint) wins if you want several distances from one sideline recording and no gates. SpeedTrackr does not do that. SpeedTrackr is two devices as practice start and finish gates for one elapsed time (second can be Android, iPhone, or a laptop), plus jump, VBT, and reaction, with Coach Mode on the web app and the Android app. Use Metric for that multi-distance profile. Use SpeedTrackr when you want honest start and finish gates.
Can coaches keep times under athlete names?
Yes. Coach Mode is on the web app and the Android app. It saves athletes and tags start and finish times, reaction, jump, and VBT under the right name. Export session data to Excel when you want a sheet outside the session. This is roster and export support, not a full coach operating system.
Is it free?
Free to start. Premium unlocks extra timing sessions in-app. Check Google Play for current tiers - we do not invent prices here.
