Quick start

With a survey:

1. Tap the Simple Grading card on the Home screen.
2. The wizard asks how to grade. Tap New Survey to record one, or Load Survey/Design to use an existing file.

3. Survey the route end-to-end (skip if loading), then save.
4. The Simple Grade dialog opens. Set the Grade % and pick Direction (Down or Up). Adjust Depth Offset if you want to raise or lower the entire plane.

5. Tap Apply Design.
6. Calibrate the benchmark if prompted.
7. Tap Start in the sidebar. Grade.

Without a survey (Enter Grade Only — Manual Grade):

1. Tap the Simple Grading card.
2. Tap Enter Grade Only in the wizard. The app jumps straight to the Grade tab in Manual Grade mode — the Simple Grade design dialog is not used.
3. The Grade screen opens with an inline Set Grade bar across the bottom of the map. Type your target grade (for example 0.30), pick Downhill or Uphill, optionally enter a Depth Offset (inches, or cm in metric) to cut below the anchored reference, and tap the green Set Grade button. 0% is allowed for a level pad.
4. Drive to the start point and lower the blade onto the ground.
5. Tap Start in the sidebar.
6. A Ready to Start? confirmation dialog appears showing your grade and direction. Tap START — the app locks your current GPS position as the 0+00 reference and begins grading from there.

The sidebar in this flow shows a Change Grade button (not the Simple Grade design chart). Tapping Change Grade halts the controller and closes the current segment; the inline Set Grade bar stays on screen pre-filled with the prior values — edit them, tap Apply, then tap Start (which shows the Ready to Start? dialog again to anchor the new leg's 0+00).
