- Change Map: The map screen control for choosing a different map type.
- download (for offline use): To save supported map data for offline use on the current device.

- map screen: The main screen where you view maps, routes, tracks, waypoints, and GPS position.
- map type: A selectable map source or style, such as a topographic or road map type.
- Place Info: Information shown for a selected place or point on the map.
- Search: The feature used to find places, roads, postcodes, and features by name.

- UTM: Universal Transverse Mercator, a zone-based coordinate system that uses eastings and northings in metres.
Routes, Tracks And Waypoints
- Activity: A fixed OMN4 classification containing Route and Track calculation, Route/Track/Waypoint appearance, and configured-destination preferences.
- Add Waypoint: The map action for creating a saved point.
- folder: A container for organising Routes, Tracks, and Waypoints. Folders do not supply Activity or appearance.
- custom: An appearance value owned by a Route, Track, or Waypoint rather than supplied by its Activity.
- from Activity: An appearance value supplied by the item's Activity because no custom value is present.
- GPX: A file format used to exchange routes, tracks, and waypoints between mapping apps and GPS devices.
- Goto Grid Reference: The map menu or floating action button entry that opens coordinate entry.
- Go to Grid Reference: The window or page title after Goto Grid Reference opens.
- Points Explorer: The tool for viewing and working through points in a route, track, or waypoint set.
- route: A planned line made from ordered route points.
- Routes, Tracks & Waypoints: The OMN4 area for creating, importing, organising, and managing route data.
- inherit / inherited: Use a property's value from the item's Activity because no custom value is present.
- legacy style value: An older numeric line width, icon size, or map text size outside the current preset list. OMN4 preserves the exact value until you choose a current value or resume inheritance.
— Multiple —: A display-only Properties state shown when selected items have different Activities, sources, or values. It is not a value that can be applied.- No symbol: An explicit Waypoint choice to display no symbol. It is different from Reset.
- parent: The folder immediately above an item or folder in Routes, Tracks & Waypoints.
- Reset: Remove one local appearance value so the Route, Track, or Waypoint uses its Activity value.
- Reset appearance: Remove every custom Route or Track appearance value without changing Activity.
- track: A recorded or imported line, often made from GPS points.
- tracklog: A recorded GPS track created while you travel.
- waypoint: A saved point on the map.
Account, Sync And Platforms

- desktop / mobile: Desktop means the OMN4 app experience on desktop computers. Mobile means the OMN4 app experience on phones and tablets.
- free trial: A time-limited trial of subscription features.
