About this app

Pace Calculator is a clean, fast tool for runners and walkers — work out your pace, finish time or distance in seconds, completely offline. Enter any two of pace, time and distance and the app solves for the third, then shows your equivalent speed and a full set of race-distance splits.

WHAT YOU CAN DO
• Solve for Pace — enter a time and a distance, get your pace
• Solve for Time — enter a pace and a distance, get your finish time
• Solve for Distance — enter a pace and a time, get how far you went
• See your equivalent speed in km/h and mph
• Read finish times for 5K, 10K, half marathon and marathon at your pace

UNITS THAT FIT YOU
Switch distance between kilometres and miles, and pace between min/km and min/mile, with a single tap. Conversions are handled for you, so you can mix and match without doing the maths.

SPLITS AT A GLANCE
The Splits tab turns your current pace into finish times for the classic race distances — 5K, 10K, half marathon (21.0975 km) and marathon (42.195 km) — so you can plan a goal time or check whether your training pace lines up with your target.

LEARN AS YOU GO
A built-in Learn tab explains, in plain language, how pace and speed relate, how the pace–time–distance triangle works, and why a few seconds per kilometre add up over a long race.

WORKED EXAMPLE
Run 10 km in 50:00 and the app returns a pace of 5:00 min/km and a speed of 12 km/h. Hold that pace and your marathon finishes in about 3:30:58.

PRIVACY
The app collects no personal data and works fully offline — your inputs never leave your device. Ads are served by Google AdMob, which may use an advertising identifier as described in Google's policies.

EDUCATIONAL USE
Results are mathematical estimates based on a single, steady pace. Real-world finish times vary with terrain, weather, fatigue and fuelling. Use this app for planning and learning, not as a guarantee of performance, and train sensibly.

Light and dark themes, a tiny download, and no clutter. Download Pace Calculator and run your numbers with confidence.
