Limits
- MTL Explorer can't add data your files don't have, such as missing timestamps or elevation.
- Energy and exploration are estimates.
- Duplicates, and tracks excluded from statistics in Review, don't count there.
- Route planning needs downloaded routing data. Online maps, 3D terrain, and trail layers need the internet.
- Offline, you only see what this browser already loaded. MTL Explorer does not record activities.
- Google Health is in beta and needs your own Google API access. Its dates are separate from the track filter.
- Photo counts follow the time span of your filtered tracks and the All media / Track related choice.
Demo
The public demo uses public Porto taxi tracks and generated data. Its health data is made up. You can't connect a Google account in the demo.
