Time Calculations

Do calculations on hours, minute, seconds. Convert hours, minute, seconds to decimal times and back again.

3 Ways to use it

Pre-race planning, on-the-go workout checks, and quick coaching math during a session.

1 Clear interface

A single-purpose calculator UI keeps attention on the calculations you need, not on dashboards and menus.

24/7 Ready on your devices

Use the same core calculator behavior across iPhone, iPad, Android, and the Apple Watch companion.

Calculate pace, finish time, and splits fast.

Pace Time keeps the interface direct: large tap targets, fast number entry, time-aware formatting, support and privacy pages on the site, and an Apple Watch experience tuned for quick actions instead of hidden gestures.

Fast pace and time entry

The calculator supports time-style input with colons and decimals, making it practical for race predictions, split checks, and distance-based pace math.

Made for athletes and coaches

Use it while writing workouts, checking a target finish time, comparing two race scenarios, or answering “what pace is that?” without breaking flow.

Apple Watch companion

The watch app keeps the controls explicit and large enough to use quickly, including direct access to convert and other operations from your wrist.

Focused on the calculations runners use

Use it for 5K, 10K, half marathon, marathon, and workouts.

Pace Time is not trying to be an all-in-one training platform. It is a dedicated running calculator for the moments when you need the math immediately: before a race, during a workout, or while adjusting pacing strategy with an athlete.

  • Quick checks for 5K, 10K, half marathon, marathon, or custom distances
  • Useful for interval sessions, threshold runs, and race-goal conversations
  • Calculate triathlon transition times and analyze each stage of your race
  • Clean enough for beginners, fast enough for experienced coaches
