DM Track — Support

Support for the DM Track apps: DM Track Timer (iPad), DM Track Remote (iPhone), and DM Track Booth (Mac). If you don’t find your answer here, email josh@dependentmedia.com and a human will reply.

Quick start on iPhone — time your first race

1. Open the app and tap Solo Timer.
2. Allow camera and microphone access. The camera records the finish; the microphone listens for the gun.
3. Point the phone at the finish line.
4. Tap Arm gun, then fire the starter (a loud clap works for testing). The clock starts on its own. Or tap Start to begin manually.
5. Tap the lane numbers as athletes cross.
6. Tap Stop, name the race, and save.

You need nothing else — no other devices, no network, no account.

Quick start on iPad — run a meet

1. Open DM Track Timer and dismiss the welcome sheet.
2. Open the sidebar with the button in the top-left corner.
3. Tap New Meet and pick a template — for example High School (JV / Varsity). This builds the whole event list, split by division and gender.
4. Tap Roster to add athletes. To add a lot at once, use the sidebar gear → Import Roster and paste one athlete per line as First Last (Team).
5. Open a division to reach its heat, and put athletes in lanes. Heats can also be seeded from past marks.
6. Tap Time This Heat, start the race, and tap lane buttons as athletes cross.

Everything above works on one iPad with no network connection and no account. Cameras, iPhones, an Apple TV scoreboard, and a Mac are all optional additions.

Which app do I want?

• DM Track Timer (iPad) — run and score a whole meet: schedule, roster, heats, timing, results, scoreboard.
• DM Track Remote (iPhone) — time a single race by yourself with Solo Timer, or act as a camera angle at a bigger meet.
• DM Track Booth (Mac) — the control room: multi-camera switching, graphics, replay, and broadcast.

Fixing times after the race

Open a saved race from Races or the Recent list. The video plays back with an audio waveform underneath — the starting gun is usually the tallest spike in that waveform.

• Adjust a time: tap the finish in the list. The video jumps to that moment and the controls open. Use Set here to snap it to the current frame, or the −0.10 / −0.01 / +0.01 / +0.10 buttons to nudge.
• Add a finish you missed: scrub to the crossing and tap Add finish at playhead, then pick the lane. It sorts into its correct place automatically.
• Fix the start: find the gun in the waveform, scrub to it, and tap Gun was here. Every finish time shifts together.
• Change a lane: tap the finish, then pick the lane number in the controls.
• Delete a mis-tap: swipe left on the finish.

Frequently asked

The gun isn’t starting the clock

Make sure you tapped Arm gun first — the meter moves whenever the app is open, but a detected sound only starts a race when armed. Watch the level meter while someone claps: if the bar barely moves, lower the sensitivity threshold; if it triggers on crowd noise, raise it. On a windy day, manual Start is more reliable than any microphone.

How accurate is it?

As accurate as your frame rate. One frame at 30 fps is about 33 milliseconds; at 240 fps it is about 4. Set the frame rate on the Solo Timer screen — the app shows what one frame is worth as you change it. Higher frame rates use more storage and may reduce the capture resolution on some devices.

Where are my recordings?

Inside the app, under Races. They are stored privately in the app, not in your Photos library. When the app’s storage allowance fills, it removes the oldest video clips first — recorded times are always kept, even after a clip is cleared.

Do I need an internet connection?

No. The Solo Timer works completely offline. Network features (running a meet across several devices, or Cloud Sync) are optional.

The camera preview is black

Check that camera access is allowed in Settings → DM Track Remote. If you were recording when the phone locked or you switched apps, reopen the Solo Timer screen to restart the camera.

Can I use several phones and a Mac together?

Yes. DM Track Remote is also one device in a larger system — several camera phones, an iPad running DM Track Timer or a Mac coordinating the meet, an Apple TV scoreboard, and video review across angles. The devices find each other over your local Wi‑Fi, so allow Local Network access when asked.

Privacy

Solo Timer recordings and race times stay on your device. There are no ads and no trackers, and Cloud Sync is off until a coach turns it on. Full details are in the DM Track Privacy Policy.
