Description
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.
COMING SOON
— Save your favorite terraces
— Walking route to the closest sunny spot
— "Where will the sun be in 1h" view to plan a meetup
Solaro is free, made in Bordeaux, no ads. Bug reports and ideas: simon@holistic-agency.fr.
What's new (v1.1.2)
This release polishes the moments you notice most on a terrace:
• Shadows finally merge correctly, and much faster — no more 5 seconds of overlapping shadows after each pan.
• The map no longer yanks you back to your location when you've already started exploring.
• Bordeaux default location now lands on Place de la Bourse — an actual landmark, not a random street.
• A handful of network reliability tweaks so bars show up even when your signal isn't great.
