A screenshot of "0.62 m/s" tells nobody anything. Was it a squat or a clean? Rep one or rep six? Did the bar slow down across the set? The number is real, but on its own it is just a number on a phone.
The video is where the story is. So in SpeedTrackr the share video does the explaining for you.
How it works
You film the set, or import a clip you already have. The app analyses it and gives you bar speed for every rep in m/s. That part happens after the video, not live on camera.
Then you export the share video. On that video, a card sits over the lift. During each rep, as the bar travels up, the bar speed on the card counts up with it. When the bar reaches the top, the number locks on that rep's result. It lands on exactly the same value the app gave you on the results screen, so the video and the app never disagree.
The label matches the lift. Olympic lifts show PEAK VELOCITY. Squats, presses and deadlifts show MEAN VELOCITY. That is the same rule I use when reading bar speed: peak for the fast lifts, mean for the strength lifts.
The end of the set
After the last rep, the video holds on a summary card for a couple of seconds: best rep, average, and velocity loss across the set. You see every rep's bar path on screen while the summary fades in.
Two details I care about here.
A single-rep set shows one number. No velocity loss. You cannot lose speed across a set of one, so the app does not pretend you did.
If you trim the clip right after the last rep, it still ends on the summary. The card is held on the last frame, so you do not need to leave dead time at the end of your footage.
Things that used to look wrong and now do not
If you delete a rep, say the walkout got picked up as a rep, it is gone from the video too. It is not drawn and not numbered.
Loads keep their decimals. 22.5 kg shows as 22.5 kg, not 23.
Long sets show "REP 3/12" instead of a row of dots, and a rep without a usable number shows a dash and stays out of the stats.
Jumps get the same treatment
The jump share video works the same way. Before take-off the card shows a dash, so the result is not spoiled in the first frame. Air time counts up in real seconds while the athlete is in the air. On a drop jump or hop, ground contact counts up too. The number locks on landing, in the same unit the results screen headlines: inches for a countermovement jump, RSI for drop jumps and hops.
The end card depends on the jump. A countermovement jump shows height and air time. A drop jump shows RSI, contact time and height. A hop series shows best RSI, average RSI and drop-off.
As with bar speed, the jump result comes from video you record or import. Normal 60 fps works. Slow motion is the most precise option.
Why this is worth doing
For an athlete, a clip with the number on it is proof of the work, and it is easy to send to a coach.
For a coach, it is the fastest way to show an athlete why a set ended. Watching the number drop rep by rep makes velocity loss obvious in a way a table does not.
For a gym or team page, it is content that actually says something: the lift, the load, the speed, the summary. No guessing.
A simple routine for your next session
- Film from the side, phone still, whole bar path in frame.
- Analyse the set and check the rep count. Delete any walkout or false rep.
- Export the share video and check it ends on the summary card.
- Send it to the athlete, or post it with the load in the caption.

There is no native iPhone app. iPhone users use the web app.
Next time a set goes well, post the video with the numbers on it, not a screenshot.
