Know when
to go outside
Your companion for running, walking and cycling. Kiyo scores every hour of your day across six factors and points at the one worth lacing up for. No accounts, no tracking — just the answer.
Not another weather app.
A companion for the hours you spend outside.
Weather apps hand you data and leave the decision to you. Kiyo is built around your activity — it weights UV, wind, humidity and rain for how you actually train, and hands back one honest answer: when to go.
Six factors. One answer.
No black box. Every score shows its why.
Tap the score and Kiyo lays out all six factors — what's helping, what's hurting, and how much. Runners get temperature weighted up. Cyclists get wind. Walkers get rain.
Make it yours.
Nine hand-crafted palettes re-theme every screen, down to the app icon. Three ship free — try one, this page follows along. Kiyo Unlocked opens the rest.
NinjaOne and Audi Revolut F1 are unofficial concept palettes — a hint of where partnered palettes could go next.
Today is free.
Everything is Unlocked.
Free Kiyo answers today. Kiyo Unlocked watches all seven days, in every place you train, and pings you the moment a window opens — one purchase, yours forever.
