ArcPace turns the forecast into the one question a runner asks: when should I run, and how will it feel? EVERY HOUR, SCORED Each hour of the next two days gets a run score out of 100 and a pace impact in seconds per mile or km, measured against an ordinary day. Heat and humidity slow you down; a cool morning can make you quicker. The score comes from temperature, dew point, wind and gusts, rain and altitude. Thunderstorms and freezing rain cap it outright. The UV index and WBGT heat stress (the flag system used at races) are shown alongside, described rather than scored. YOUR BEST WINDOW AT A GLANCE Tell ArcPace when you can actually run, and it ranks those windows. Each one says what to wear and what to carry. TEN DAYS AHEAD Each of the next ten days scored from its worst hour to its best. Open one for its best run and the day hour by hour. WHAT THE WEATHER COST YOU With read-only access to Apple Health, ArcPace scores your last sixteen weeks of runs against the weather they were run in. A slow July run reads "Humidity set this pace, not you", with what it was worth on an ordinary day. A calendar of those weeks, a fitness trend with the weather taken out, and weather-adjusted bests. ALSO • A Home Screen and Lock Screen widget with this hour's score and your best window ahead • An optional notification with tomorrow's best window • A share card for any run • Saved locations for travel planning • Imperial or metric, light or dark, Reduce Motion and Dynamic Type respected PRIVATE BY DESIGN No account, no ads, no analytics, no server of our own. Your runs are read and kept on the phone; to score one, only its approximate place and hour go to Apple Weather. Your location goes only to Apple Weather. ArcPace is free. If it earns a place in your routine, you can leave a tip from Settings. ## Key features - Hourly run scoring - Pace impact calculation - Weather-adjusted run analysis - Clothing and gear recommendations - 10-day forecast scoring - Home and Lock Screen widgets ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Tip: Buy me a coffee | $2.99 | one-time | | Tip: A pack of gels | $5.99 | one-time | | Tip: Toward new shoes | $14.99 | one-time | | Tip: Buy me a coffee | $2.99 | one-time | | Tip: A pack of gels | $5.99 | one-time | | Tip: Toward new shoes | $14.99 | one-time | ## Is ArcPace safe?

It’s super easy to use and gives you a running score based on your current location, so you can quickly see whether it’s a good time to head out for a run. It also provides recommended running times for the day and even suggests what to wear based on the conditions. Another great feature is that it syncs your fitness watch’s running records with the running score for that time, helping you see how the conditions relate to your run. The app is still evolving, with new features being added along the way. Highly recommend giving it a try if you enjoy running or spending time outdoors! ### 5/5 — I like it *2026-10-15* Useful information for runners ### 5/5 — Phenomenal.

This app helps me do it, without any fluff. ## Frequently asked questions about ArcPace ### What is ArcPace? ArcPace is a weather app designed specifically for runners.
