How much harder is today’s hike, run or ride?
TerrainIQ is a free Android activity tracker that turns live weather, air quality and terrain into one number: how much harder today really is. You get an effort-adjusted pace, a spoken AI briefing before you start, live slope and elevation, and safety alerts.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
