Data Overlay

What are you making an overlay for?

Pick a sport to see its gauges, then try things: turn gauges on and off, drag them around, change units and colours, and scrub through the sample activity. Switch sports any time with the Modes button.

Drop a file here FIT, GPX, TCX, KML, CSV, UDDF or Subsurface — the mode is chosen from the file where it can tell.

This demo runs on sample data. In the app, your own files are read on your computer and never uploaded. Data Overlay draws gauges from recorded data for video — it is not for navigation or dive planning.
