Frequently asked questions
Which cameras and video formats are supported?
Any video in your phone’s gallery — footage from the phone itself, GoPro, DJI or any action camera, once it’s imported to the gallery. The overlay is matched by the time the video was filmed, so make sure your camera’s clock is set correctly.
How does syncing work? Do I need to align anything manually?
No. The app reads the video’s creation time and finds the Apple Watch workout that was running at that moment. Speed and metrics are aligned to the second automatically.
Are my videos uploaded anywhere?
Never. Rendering runs entirely on your phone with FFmpeg. No accounts, no cloud, no uploads — see the Privacy Policy.
Why is a metric greyed out?
That workout simply doesn’t contain it: power and cadence need sensors, heart rate needs a watch or strap, the map and altitude need a GPS track, temperature needs a thermo sensor.
Is Pro a subscription?
No. Pro is a one-time purchase — pay once, keep it forever on your platform. Refunds are handled by the App Store / Google Play under their standard policies.
