Release notes, new features, and improvements.
v1.3.0Latest
March 2026Average Speed, Power Graph & Elevation Zoom
Two new overlay types, a scrolling elevation graph that zooms into the terrain around you, and several export and stability fixes.
Features
- +New Average Speed overlay — shows current average speed with progress bar and delta indicator across all 4 themes
- +New Power Graph overlay — visualizes power output over distance, matching the elevation graph style
- +Elevation graph View Range — zoom into 1 km, 2 km, 5 km, or 10 km around your current position with auto-fit vertical scaling
