Latest release

What’s New

Version 1.0.1 Apr 1, 2026

We refreshed the map screen: compact controls for Follow, North up, and map appearance (standard, muted, hybrid, satellite). Start and Stop are clearer, with a consistent size — green outline when tracking is on, red when it’s off. In Settings → Trail history, you can choose how long your path stays on the map (or turn it off). Trail segments use speed-based colors as a simple hint (walking, cycling, motorized). Smaller polish and stability improvements around the map and controls.

Baseline captured. Growth appears after the crawler observes a changed rating count.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
