Every cyclist knows the question: what should I wear today?
A normal weather app can tell you the temperature. Maybe the rain chance. Maybe the wind. But it rarely tells you what those conditions mean once you are actually on the bike -- and it definitely does not know what cycling gear you own.
That is why we built ONNYON.
ONNYON is a cycling app that helps riders decide what to wear using their own wardrobe, weather, route timing, and cycling-specific conditions. Instead of giving generic advice, ONNYON turns the gear you already own into practical outfit recommendations for the ride ahead.
Built around your actual wardrobe
ONNYON starts with your cycling clothes.
Add your jerseys, bibs, jackets, vests, gloves, warmers, shoes, shoe covers, helmets, eyewear, and more. Once your wardrobe is in the app, ONNYON uses it as the foundation for every recommendation.
That means the app does not just say "wear a jacket." It can help you choose from the jackets, layers, and accessories you actually have.
The more complete your inventory is, the better ONNYON can help you prepare.
Weather, the way cyclists read it
Cycling is not just about the number on the weather forecast.
Wind, real-feel temperature, rain, exposure, road surface, spray risk, and timing can all change what you should wear. A ride that starts dry can become cold. A mild day can feel exposed in the wind. A road can stay wet long after the rain has stopped.
ONNYON is designed to translate those conditions into practical clothing decisions.
Route-aware outfit planning
What you wear should depend on the ride you are actually doing.
A short flat spin, a climb into cooler air, a long descent, an exposed road, or a ride that starts now and finishes hours later can all require different clothing choices.
ONNYON factors in route and timing so recommendations are not based only on where you are standing at the start.
And when you do not have a route file, Ride Points let you add a start point and up to two key places where conditions may change most.
Privacy-first by design
ONNYON is built with a local-first approach.
Your wardrobe data lives on your device, and recommendations are generated locally. The goal is simple: make the app useful without collecting unnecessary personal data.
What comes next
This is the beginning of ONNYON.
We are building toward a smarter cycling preparation tool -- one that brings together your gear, the conditions, the route, and eventually the cycling brands that best match your needs.
The goal is not to replace your judgment.
The goal is to make getting ready easier, faster, and more confident.
ONNYON is here. Layer up and ride.
