Sun AI tells you when it's good to go outside.

Most weather apps hand you four numbers and leave you to work it out. Sun AI reads UV, air quality, rain chance and how hot it really feels, then scores every hour of your day — so you get an answer, not homework.

HOURLY OUTDOOR SCORE

Every hour from early morning to evening gets a score from 0 to 100. The app finds the best stretch, tells you when it opens, and tells you why it closes.

BUILT AROUND WHAT YOU'RE DOING

Cycling cares more about wind and heat. Time with kids applies stricter UV limits. A short walk tolerates what a long run would not. Pick your activity and the answer changes with it.

LIVE UV AND AIR QUALITY

Current readings for where you are, plus how they move through the day. Hourly PM2.5, PM10, ozone and NO₂ for anyone who needs the detail.

ALERTS THAT ARRIVE BEFORE YOU LEAVE

Heavy rain, high UV, extreme temperature or poor air — sent in the morning, at the time you choose. Free covers where you are now; Premium covers every place you've saved.

ASK ABOUT YOUR DAY

A built-in assistant that answers using the real forecast for your location. What to wear, when to run, whether to bring an umbrella.

HOME SCREEN WIDGET

Temperature, UV and your best hours without opening the app.

SAVE THE PLACES YOU CARE ABOUT

Home, work, where your parents live, where you're heading this weekend.

FREE AND PREMIUM

Sun AI is free to download. Free covers current conditions, hourly forecasts, UV, air quality and five AI questions a day with a free account.

Premium adds the hourly outdoor score with activity profiles, hourly pollutant detail, alerts for every saved place, more saved places, and fifty AI questions a day.

SUBSCRIPTION DETAILS

Premium is available as a monthly or yearly subscription. Prices vary by country and are shown in the app before you subscribe.

Each subscription starts with a 3-day free trial. Payment is charged to your Google Play account when the trial ends. Your subscription renews automatically at the same price unless you cancel at least 24 hours before the end of the current period. Manage or cancel your subscription in the Google Play app, under Payments and subscriptions. Deleting the app does not cancel a subscription.

PERMISSIONS

Location is used to show the weather where you are. The app works without it — search for a place instead.

Notifications are requested only when you turn on a weather alert.
