About this app

Just a simple, ad-free, in-app-purchase-free running pace calculator. It calculates the pace you need to hit your running goals - perfect for 5K, 10K, and (half-)marathon training.  Store your favorite paces, e.g., your goal marathon or 10K times - all data saved locally on your device. No tracking, third-party libraries, or other nonsense. It does exactly what it says on the tin, and nothing more.

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.
