Dromeas

Running Calculator & Planner

Free · Designed for iPad. Not verified for macOS.

Every running calculator in one place — pace, VO2max, race prediction, training zones, splits. Now on Apple Watch. 100% offline, no account, no ads. Dromeas is a simple, focused running calculator — everything you need to plan a run or check your numbers after one, with no ads, no account, and no tracking. CORE CALCULATOR Enter any two of pace, time, and distance to instantly get the third. Quick-select common race distances from 1K to Spartathlon, switch between km and mi with one tap, and scroll through wheel pickers built for speed. SPLITS See a full kilometer-by-kilometer or mile-by-mile split breakdown for any pace and distance, generated instantly. FAVORITES Save any pace/time/distance combination you use often — a goal race pace, a recovery run pace, whatever you come back to — and reload it in one tap. MORE TOOLS • Race Predictor — estimate your finish time at any distance from a recent race result, using the Riegel formula. • Training Paces — get Easy, Marathon, Threshold, Interval, and Repetition paces from your threshold pace. • VO2max Estimator — estimate your aerobic fitness from a recent race performance. • Heart Rate Zones — get your five training zones from your max or threshold heart rate. • Critical Speed — find your sustainable speed and D′ from two or more race results. • Grade-Adjusted Pace — see your flat-equivalent effort on a hilly route, using a real physiological model of the energy cost of climbing and descending (Minetti et al.). • Calories Burned — estimate energy expenditure from your weight, distance, and time, using the ACSM running equation. ON YOUR WRIST A full Apple Watch app: turn the Digital Crown to read one pace four ways at once, work out a pace from a distance and a time, and reach your Favorites straight from your wrist. A watch face complication keeps your last pace one tap away. MAKE IT YOURS Choose Light, Dark, or System appearance, and pick an accent color — Blue, Orange, Green, Yellow or Magenta. PRIVATE BY DESIGN Dromeas makes no network requests. There's no account, no analytics, and no ad tracking. Your Favorites and preferences stay on your device — the only place they ever travel is your own Apple Watch, over Apple's local connection, never to a server. Read the full privacy policy in the app or on our website. Whether you're pacing a workout, predicting a race time, or just doing quick running math, Dromeas gets you the number and gets out of your way.
