Run Window vs RunIntensity

You already know you want to run today. The only question is when. Run Window is the running weather app that gives you one answer. Tell us what conditions you actually like — cold mornings, humid afternoons, a little rain — and we'll scan the hourly forecast for the best time to run today. Your best running window shows up the moment you open the app. No guessing. No cross-referencing three weather apps. Just: here's your hour, go. Try Run Window free for 7 days — no credit card required. After your trial, plans start at $5.99/month. WHO IT'S FOR Runners who run outside. Marathon training, easy days, race-week tapers, the half-marathon block you can't skip. If your schedule has a 2–4 hour window most days, Run Window finds the hour inside it where conditions line up — temperature, humidity, wind, dew point, AQI, all of it. HOW IT WORKS We start with four quick scenarios: would you head out in 35° wind? 88° humidity? Steady rain? Then you tell us when you usually run. Your answers build a comfort profile that scores every hour of the forecast against what you actually enjoy. The result is a window — a specific block of time where conditions line up for you. Not some generic "good running weather" label. Your window, based on your preferences. WHAT YOU GET • Your best windows — open the app, swipe through them, plan one to the quarter hour • 16 days of hourly forecasts — scored and ranked to your comfort zone • Today's verdict each morning — a notification with your window before you head out • Weather watch — we track conditions for your planned runs and tell you if anything shifts • Learns from your runs — tell us how it felt, and your windows get sharper • Plan your week — see ten days at a glance, mark rest days, build your schedule around the weather • Backup windows — not just the best hour, but your second and third options too BUILT FOR RUNNERS WHO RUN OUTSIDE We know you're going regardless. Run Window just helps you pick the hour where it'll feel the best. And when conditions are genuinely rough, we'll say so — no sugarcoating. We watch the running weather forecast. You go run.

Your 40 miles this week hit like 55. RunIntensity is the running app that knows the difference. Distance and pace don't tell you how hard a week really was. A hilly run in the heat or a tempo on tired legs costs more than the mileage suggests. RunIntensity scores every run in Stress-Adjusted Miles (SAM), a five-factor training load model built from heart rate, terrain, surface, cumulative fatigue and conditions. Your weekly mileage becomes a weekly training load you can plan around. TWO NUMBERS, ONE ANSWER EVERY MORNING RunIntensity reads what your watch already writes to Apple Health and scores two things separately, 0–100: • Recovery — heart, nervous system and sleep. HRV, sleep and resting heart rate against your own baseline. Snaps back overnight. • Freshness — muscles, tendons and joints. How much of your recent training your legs have absorbed. Drops with a hard session, climbs back over hours or days. Then one call: Ready, Steady or Recover. Ready only when both are high; Steady when one system is still catching up; Recover when rest is the workout. Recovered isn't the same as healed — this is the app that knows when you're overdoing it.
