A Bad Picnic Changed Everything
Grey skies. Wrong park. Sad sandwiches. There had to be a smarter way. A few weeks and one very patient weather API later, Where Sun was born — and the next picnic was genuinely perfect.

Night Mode: The Sun Has a Bedtime
The sun clocks out. The app notices. After dusk it shifts into a deep, warm palette — darker reds, softer whites. Not because we had to. Because planning tomorrow's sunshine at midnight should feel like that. Quiet. Considered. Still excited.

Why the App Feels Like a Warm Hug
Red and warm white. Inter at 900 weight. A sun that idles like it's been waiting for you. Every single pixel decision was made to feel like stepping outside on a perfect day — even before you've found one.

We Spent 4 Months Building Features You'll Never Notice
Before anyone could pay us a single euro, we built the entire premium system invisibly. Search limits, save caps, daily counters — all running silently in the background. No paywalls, no pressure. Just a counter that counted and said nothing. We wanted to earn the right to charge before we asked.

We Found 18 Bugs in One Afternoon
We sat down for what we called a "deep audit" of v0.8. Two hours in, the tally was at 18. Parallel fetch crashes, timezone parsing wrong in half the world, GPS spinners stuck forever, night mode colors bleeding into the wrong screens. We fixed all 18 before shipping. Zero known bugs at launch is the only metric that matters.

How We Actually Find the Sun
One search fires two parallel data sources — Overpass finds cities and towns, Nominatim finds parks, beaches, and nature reserves. We mix them together so you get real variety, not just a list of nearby cities. Then we check the weather on all 16 candidates at once. The whole thing, including cache hits, takes about 2 seconds. That's the whole trick.

Privacy · July 2025
No Backend. No Accounts. Seriously.
No server storing your data. No account to create. No password to forget. Everything lives on your phone. We made a deliberate list of things we are not building: no server-side database, no push notifications from a backend, no calendar writes, no home screen widgets. Every "no" makes the app lighter, faster, and simpler. Simple is hard. We're doing it anyway.

Speed

The Day We Made It Twice as Fast
v0.9.2 was purely about speed. Weather fetching and place discovery now run at the same time instead of one after the other — roughly halving the wait. Search the same area twice? The second one is instant from cache. We also added a "week insight" banner: if Thursday is sunnier than Saturday, we'll just tell you. You can thank us later.
Roadmap

What's Coming After We Launch
We have a list. Organized lists for saved places (like Google Maps), calendar export for planned trips, weather alerts when a favourite spot turns sunny, an Apple Watch glance, a golden hour calculator for photographers, and Siri that answers without you opening the app. We wrote it all down so we don't forget. Most of it will ship. Some of it won't. We'll tell you either way.

How this app
was born.

It was overcast. We wanted sun. Somewhere.

Her: "We just need to figure out where it actually is."
Him: "...wait. Isn't that literally an app already?"

A few minutes later.

Him: "wait... it's not. I'm making this."
Her: "What would you call it?"
Him: "Where Sun."
Her: "...awesome."

That's it. That's the whole story.
