Sunny Side DownFind the seat the sun can’t reach.
You know the drive where you spend the whole time with a hand up against the glass, trying to keep the sun off your face, and arrive sweating anyway? That was a seat choice you made without thinking, forty minutes earlier. Sunny Side Down makes it for you.

Roads bend, and the sun keeps moving. A seat that’s cool when you set off can be roasting by the time you arrive, so glancing at the sky tells you almost nothing.
Sunny Side Down checks where the sun will be along every stretch of your journey and adds it all up. The answer covers the whole trip, not just the moment you leave.

What else it does
- Tells you when the sun swaps sides mid-journey, so you can swap with it
- Shift your departure time and watch the answer change
- Follows your progress live as you travel
- Save the journeys you make often, rechecked fresh each day
- Works anywhere, right-hand drive or left — it never suggests the driver’s seat
- At night it simply tells you to sit wherever you like. The sun is asleep.
Quiet by design
No account, no sign-up, no ads. Your saved journeys stay on your phone — there’s no server of ours for them to sit on. Location is optional: grant it and the app knows where you’re starting from, decline it and you just type a starting point instead.
Want to try it?
It’s in closed testing — which means it works, but it’s young, and the group trying it is small. Anyone can ask to join.
- Ask to join the testers group — it’s open, you just request access.
- Once you’re in, opt in on Google Play and install as normal.
If something looks wrong — a verdict that seems backwards, a place it can’t find — tell me and I’ll fix it.
