## What is Sun Bath?

Sun Bath answers one question with precision: when will sunlight actually reach your window?

Drop a pin on a satellite map, aim a dial the way your window faces, and Sun Bath computes your exact minutes of direct sun. Today, tomorrow, and every month of the year. All of it on your device, with no accounts and no ads.

Made for plant parents, apartment hunters, golden-hour chasers, and pets who follow the sun.

SUN ON YOUR WINDOW, TO THE MINUTE
Open the app and the first thing you see is when the sun arrives on your window, and how long it stays.
– Scrub the day arc to watch exactly where the light will land, hour by hour
– A forecast card blends real cloud cover and UV into the picture, so a sunny window means actually sunny
– Skylights welcome: no compass direction needed, just the open sky

FOR YOUR PLANTS
Name a window for any plant. One tap ranks every spot in the house by who has sun right now and for how long. The Seasonal tab shows each window's whole year of light, so you'll know the sill that is perfect in June but dim in December before your plants do.

REMINDERS THAT WORK WHILE IT'S CLOSED
Choose the windows you care about and a reminder arrives just before the sun does: "Sun arrives in 20 minutes and stays until 3:55 PM." Every reminder is timed to its own window's light, in that place's own timezone, and scheduled entirely on your device. No server ever wakes you up; the sun does.

A YEAR OF LIGHT
The lower the sun rides, the deeper its light pours into the room. That's how the window facing the winter sun becomes a gentle heater just when you want one, and why a skylight is the inverse. The Seasonal heat map lays out your window's entire year at a glance, paired with typical monthly warmth for your area, and it tells the truth for your latitude, from the tropics to the midnight sun.

EXPLORE THE WORLD
Then ask the bigger question: where in the world has the most sun today?
– Browse curated cities ranked by real climate data
– Search almost any town on earth, each one showing its distance from your window
– Or stay close and ask within 100 miles of home, ranked by the live forecast
– Every city wears its living sky: the actual light there right now, sunrise to sunset

MEET YOUR COMPANION
A small companion reacts to your real sun and weather: basking when the light is on your window, dozing through grey days. Choose a dog, a cat, or a bit of both.

PRIVATE BY ARCHITECTURE
No accounts. No subscriptions. Every sunbeam is computed on your device with pure solar geometry, so Sun Bath works anywhere on Earth, even offline. Weather and UV come straight from Apple's own WeatherKit.

Whether you're placing a monstera, sizing up an apartment's real afternoon light before you sign, timing golden hour on your own balcony, or just deciding where to drink your coffee, Sun Bath knows where the light will be.

Sun Bath is made by one person who thinks about light more than is probably reasonable. If your window's sun ever seems off, or you have an idea, I'd genuinely love to hear it.
