Personal Bests

Personal Bests helps you discover your fastest efforts hidden inside your workouts.

Most fitness apps only show totals: total distance, total time, average pace.
Personal Bests goes deeper.

It analyzes every workout in Apple Health and finds your fastest segments of any length, then ranks them across all your workouts and timeframes.

Need to find your fastest 7K segment within the last year?
Your fastest 1-mile effort ever, even if it happened in the middle of a longer run?
Your best 500m row, 5K ride, or 1K swim?

Personal Bests will find it.

Segment-Based Personal Bests
• Automatically finds your fastest segments for any distance you care about.
• Works across running, cycling, walking, swimming, rowing, and more.
