## Description

loop4d adds the fourth dimension to route planning: time.

You already know your route. loop4d tells you WHEN to run or ride it - the hours with the most shade on a hot summer day, or the most sun in winter - so you can plan around the heat, the glare and the wind.

Open a GPX file (or share one from Strava, komoot, Garmin Connect or Files), pick a date, and loop4d walks the sun across your whole route, point by point, to find your best time to go.

HOW IT WORKS
• Per-point sun & shade — for every part of your route, loop4d works out when the sun clears the ridges, trees and buildings around you.
• Best windows — clear "best in shade" and "best in sun" time slots for your chosen day.
• Weather & wind — temperature, rain, wind direction and twilight over your day, from a live forecast.
• Replay — scrub through the day and watch your route light up shade, sun, headwind and tailwind, segment by segment.
• Forward or reversed — flip the direction and loop4d re-picks the ideal start.

BUILT FOR RUNNERS & CYCLISTS
Marathon training in July? Find the shaded hours. Chasing winter sun on the bike? Find the bright ones. Planning a long climb? See where the wind hits.

PLAN WITHOUT AN ACCOUNT
Route analysis runs on your phone, with no sign-in. loop4d fetches public elevation, map and weather data to do the math.

YOUR MAP, YOUR HISTORY
Sign in with Apple and connect Strava to fill in a map of every country you've been active in, see your activities year by year, and earn awards for sun, heat, rain, wind and after-dark loops. Share any analysed route as a card.

Pick your route. We'll pick the hour.
