Fasted gives you the timer, the data, and the people to make it work long-term. Terms of service: https://getfasted.app/terms Privacy policy: https://getfasted.app/privacy

Verdict
The clearest difference is price: Fasted at Free against Activity Complications's $2.99. Fasted also leads on update cadence (every 2 weeks vs every 2 months) and iOS requirement (16.0 vs 26.0). Activity Complications's advantage is in-app purchases (none vs 3) and chart position (#194 vs unranked). On ads and device support there is nothing between them.
