  • This app hasn’t received enough ratings or reviews to display an overview.

[New] • See how your stride changes throughout a run with the redesigned Running Form views for runs and splits: a visual summary and linked charts for cadence, stride length, ground contact time and vertical oscillation, where data is available. • You can now save imported FIT runs to Apple Health. Open the run’s menu and choose “Save to Health” (requires Pro). [Improved] • Explore how your effort changes across a run or split with richer charts, including power where available, and clearer chart selections. • Missing splits in runs can now be filled in when enough recorded data is available. Estimated times are clearly labeled. • Browse a large running history more smoothly, with lower memory use during startup and sync. [Fixed] • Read your FIT runs more consistently, with fixes for recorded distances, lap timings and pauses in split views and exported files. • See weekly widget values aligned with the correct days, including after changing your week start or distance unit. • Avoid invalid best-effort times on affected runs, with fixes for out-of-order route data and inconsistent pause handling. • See your personal records reflect recalculated best efforts. After updating, opening a run may update its PB times and leaderboard positions. The run itself is not deleted.
