Tzel finds walking routes that stay in the shade, shows you live sun, UV and heat, and predicts where every shadow falls through the day.

For every walk, Tzel plans three routes and shows exactly how much of each stays out of the sun. Amber is sun, navy is shade — pick your trade-off.
The most direct line there, for when you are in a hurry and the sun can wait.
A smart mix of short and shady — a minute or two longer, a lot cooler.
Hugs buildings and tree lines to keep you in shadow for as long as possible.
Tzel weighs real building footprints and tree canopy, not just distance. Compare the fastest and shadiest options side by side and start walking the one that suits the weather.

A glance tells you the current UV index, temperature, cloud cover and a real-time “feels-like” reading — so you can decide whether to grab a hat, wait an hour, or take the shady way round.

Save home, work and your favourite café, and Tzel keeps their shade and conditions ready. Sign in with Apple to sync saved places and preferences across your devices — no account required to start.

Tzel launches with fine-grained building and tree data for a growing list of areas — and we add new neighbourhoods constantly.
Everything in Tzel is free. Pro is an optional subscription for people who walk their city every day and want a little more.
