Pace Calculator on iPhone and Android (No App Needed)

Need to check your goal pace from your phone before a race? You do not need to install anything. Any modern phone browser can run a pace calculator faster than the App Store can finish downloading one.

free pace calculator runs entirely in the browser on iPhone, Android, iPad, or any tablet. Open the page, type a distance and time, get the answer. Add it to your home screen if you want a one-tap shortcut.

Why You Do Not Need a Pace App

Pace math is two divisions and a unit conversion. There is nothing about it that needs a 50MB app, an account, or notifications. The browser version is faster, smaller, and works on every device without an install.

Pace apps make sense for tracking live runs (GPS, splits, audio cues). For checking goal pace, race predictions, or treadmill speed, they are overkill.

Add to Home Screen on iPhone

You can save the pace calculator as a one-tap icon on your iPhone home screen — it looks like an app but uses zero storage.

1. Open Safari and go to our pace calculator.
2. Tap the share icon (square with up arrow) at the bottom of Safari.
3. Scroll down and tap "Add to Home Screen."
4. Name it "Pace" and tap Add.

Now you have a home-screen icon that opens the calculator instantly. No App Store, no account, no updates.

2. Tap the three-dot menu in the top right.
3. Tap "Add to Home screen" or "Install app."
4. Confirm. You now have a home-screen shortcut.

Race-Day Use on Your Phone

Common race-morning use:

• "What is my goal pace per mile for a 1:55 half?" — type 13.1, type 1:55:00, see 8:47/mile.
• "What pace do I need to break 30 in a 5K?" — type 5km, type 30:00, see 9:39/mile.
• "If I hold 9:00/mile in the marathon, what time do I finish?" — type 26.2, type 0:00:00, adjust until pace shows 9:00 → 3:55:43 finish.

All of this in a few taps on your phone, standing in line at the porta-potty 15 minutes before the gun.
