Solaro - Terrasse sunlight

Solaro tells you in 2 seconds whether the terrace at your favorite bar is still in the sun, and for how long.

Type the address of a bar, restaurant or café. The app computes the exact angle of the sun and checks which surrounding buildings will block the facade over the next 6 hours. You get:

— A massive countdown: "47 min of sun left" — A 6-hour timeline: when it goes into the shade, when the sun comes back — A live map with shadows projected in real time — Nearby bars and cafés, ranked by sun exposure

No account. No weather. No crowdsourced database to maintain. No push notifications nagging you. Just the sun and the buildings, computed on your phone, instantly.

Solaro is built for the terrace, not the couch. The interface stays readable in full sunlight with sunglasses on, in 2 seconds, after your third drink.

WHY IT'S DIFFERENT Other sun apps tell you where the sun is. Solaro tells you whether the specific terrace you're standing on, or the one next door, is in the sun right now and until when. That nuance changes everything when it's 16°C in April and you're looking for the right spot.

WHERE IT WORKS Anywhere OpenStreetMap has building heights. Tested in Bordeaux, Paris, Lyon, Toulouse, Marseille, Nice, Nantes, Strasbourg, Montpellier and Lille. If your city has no tagged buildings, the app tells you honestly instead of making it up.
