Zeph: Weather Coach

Zeph tells you one thing: when to train. Not a 10-day forecast. Not a data dashboard. One score, out of 10, every day. Your best window to get outside and move. Most weather apps give you temperature, humidity, wind speed, UV index, and dew point — and leave you to figure out what it all means for your workout. Zeph does the thinking for you. It reads the conditions, weighs what matters for outdoor training, and surfaces a single score with a clear recommendation. Open the app, see your number, and know whether to lace up now or wait. WHAT ZEPH DOES Every morning, Zeph analyzes the hourly forecast for your location and calculates a training score from 1 to 10. It identifies your optimal training window — the specific hours where conditions are best — and tells you exactly when to head out. Tap through to see how the score shifts across the day, or check the week ahead to plan your harder sessions around the best conditions. BUILT FOR OUTDOOR ATHLETES Whether you run, ride, hike, or train in any other way outdoors, Zeph adapts to your activity. Set your preferred sport and your training hours, and Zeph tailors its recommendations to your schedule. Switch activities on the fly with a long press — your score and window update instantly. ALWAYS WHERE YOU NEED IT Zeph lives on your home screen and lock screen with widgets that show your score and best window at a glance. Enable Early Window Alerts and Zeph will notify you the night before when tomorrow's best conditions start earlier than expected — so you never miss a great morning. YOUR PRIVACY, RESPECTED No account. No login. No data sent to servers. Your location is used only to pull your local forecast. Everything stays on your device.
