Does Pace It work if I do not have an Apple Watch?

Pace It is iPhone-only for the app itself, but it runs on any watch and can sync via Strava. You lose the native Apple Watch workout app experience, but the analytics work the same on any run data that reaches HealthKit or Strava.

How long does it take to see meaningful trends?

Zone-by-zone pace progression needs several months of consistent running to show a real trend. If you already have years of history in HealthKit or Strava, the app ingests it on first setup, so trends appear immediately from your existing data rather than waiting for new runs to accumulate.

What does the free tier include, and what is behind the paywall?

The free tier includes the run diary with weekly goals, personal best tracking, workout categorisation, and the Pace It Index. The deeper analytics, including pace-at-effort progression, efficiency scatter, training trends, Training Load Ratio, and personalised paces, plus the Apple Watch workout app, are behind a monthly or yearly subscription, both with a 7-day free trial. A one-time lifetime purchase is also available.
