TZEL - HEBREW FOR SHADOW

Walk on the shady side of the street.

Tzel maps every shadow in the city, minute by minute, and routes you through them. A few minutes longer. Ten degrees cooler.

Your walk, shaded street by street.

Real shade for real streets - the fastest way and the coolest way, side by side.

WHAT IT DOES

Every building casts a schedule.

Shade-first routes
Fastest and shadiest, side by side. Every route is scored by how much of it is in shade right now, down to what the trees contribute.
The sun, scheduled
Scrub the day and watch shadows sweep the map. Leave twenty minutes later, walk half in shade.
Know before you go
UV, heat, and shade conditions for your saved places, on your lock screen before you step out.
Ask the shade guide
“Too hot to walk right now?” Ask the new shade guide: Apple Intelligence chat that answers privately, entirely on your iPhone. Unlimited with Tzel Pro.
Heat and UV alerts
When a heatwave or high UV rolls in, Tzel warns you ahead of time: feels like 44° in the sun, keep your time outside short.
Find the sun
Point your phone at the sky and see exactly where the sun sits right now: how high it is, when it rose, and when it sets. Surprisingly fun.

Also inside: Look Around previews · saved Home and Work · offline maps and alternate icons with Tzel Pro.

Right now in Tel Aviv, it’s 15:30.

The whole page runs on the same clock as the app. Drag the sun in the hero and watch the streets - and this dial - follow.

WHERE IT WORKS

Shade wherever streets are mapped.

Tzel builds its shadows straight from the map, so it works in most mapped cities worldwide. We're starting where the sun works hardest: a handful of the sunniest cities get the full treatment - building and tree data tuned by hand, street by street, all working offline - and the list keeps growing. Everywhere else, Tzel runs on community map data we haven't checked yet, so quality can vary.

The sunniest cities first, tuned by hand+ community-mapped cities worldwide
