UV Index: Sun & Tan Timer helps you understand today's UV and plan your time outside with clear, personalized guidance — at the beach, on a run, hiking, or anywhere in the sun. Most sun apps hand you a raw UV number. This one tailors it to you: your skin type, your location, this moment — so you know what it actually means for your skin. CHECK LIVE UV Real-time UV index for your exact location
Today's peak UV and how the day's UV rises and falls
See conditions at a glance from your Home Screen widget. KNOW YOUR BURN-RISK A personalized burn-risk estimate based on your Fitzpatrick skin type
An estimate of how long you can be out before you're at risk
Clear "seek shade" guidance when UV is high. FIND LOWER-RISK WINDOWS See when the sun is gentler earlier and later in the day
Plan outdoor time around today's lower-risk windows
A 7-day UV outlook to plan the week ahead. TRACK YOUR SUN SESSIONS (PREMIUM) Start a sun session timer with a burn-risk alert before you've had too much
Exposure history — every session logged
Personal insights: total sessions, time tracked, and average peak UV. DAILY PROTECTION GUIDANCE Simple SPF and shade guidance based on today's UV, your skin type, and location. WHY IT'S DIFFERENT
Built on one honest idea: there's no such thing as a "safe" tan, but there is a smarter way to be in the sun. Instead of pushing you to maximize color, it helps you understand your burn risk and make your own call. SUBSCRIPTION
Powered by live UV and weather data. Premium unlocks the session timer, exposure history, 7-day outlook, insights, and widget. Subscriptions auto-renew unless canceled at least 24 hours before the period ends; manage or cancel anytime in your App Store settings. Provides estimates and guidance only — not medical advice, and it can't guarantee you won't burn. UV conditions change and individual skin responds differently; always use sun protection and follow professional medical advice when needed. DISCLAIMER UV Index: Sun & Tan Timer provides UV information, burn-risk estimates, and general sun-safety guidance for informational purposes only. It does not provide medical diagnosis, treatment, or advice. Burn-risk estimates are based on population data for skin type and UV levels — individual skin responds differently, and the app cannot guarantee you will not burn. UV conditions can change throughout the day. Always use appropriate sun protection and consult a qualified healthcare professional with any questions about sun exposure, skin health, or your individual risk.

Tiny Skies turns the weather forecast into a tiny world. Your city is drawn as an isometric miniature diorama — its real landmarks, streets and rivers on a small block of land — and the scene changes with the weather outside your window: clouds drift over it, rain falls on wet streets, snow settles on the roofs, fog rolls between the towers, lightning flashes over it at night. WEATHER YOU CAN SEE • Current conditions, feels-like temperature, wind and humidity, with an hourly strip and a 7-day forecast • Data from Apple Weather • Morning, day, evening and night versions of every scene, so the diorama follows the light as well as the weather A LIVING SCENE • Tilt your phone and the diorama shifts with depth; drag it to look around • Rain, snow, fog, clouds and lightning are animated live on the scene • Animate turns a scene into a short looping film ON YOUR HOME SCREEN • Small, medium and large widgets show the current scene and temperature and update through the day • Lock Screen widgets with the temperature and conditions • Works with tinted and clear Home Screens A CITY EVERYONE DRAWS TOGETHER • Your current location or any city in the world • Every city's scenes are shared: when anyone draws a city's weather, everyone who follows that city gets it, instantly and free • Found a city: be the first to draw it, and it's yours • Share a card of today's scene FREE, WITH TINY SKIES PLUS FOR MORE Tiny Skies is free: the real weather, the built-in artwork, the widgets, every community scene of your cities and one AI scene of your own. Tiny Skies Plus draws new scenes of your cities as the weather and the light change, with 10 scene credits a month — each scene drawn costs 1 credit (a new city's first view also draws its base scene), a private redraw just for you costs 1, and an animated loop costs 3. Credits reset on the 1st. Plus members also put their name on the cities they found and can claim cities founded by free explorers. Tiny Skies Plus is an auto-renewable subscription, monthly or yearly. Payment is charged to your Apple Account when you confirm the purchase, and the subscription renews automatically for the same price and period unless you cancel at least 24 hours before it ends. Manage or cancel it in Settings → your name → Subscriptions. Scenes are generated by AI image services (Google's Gemini models, fal.ai for some styles) after you confirm you are 18 or older; without that, Tiny Skies still shows the real weather over its built-in artwork. Each new scene takes about a minute to draw and needs a network connection. Tiny Skies has no accounts, no ads and no tracking. Founder names are public and follow the community rules (tinyskies.app/rules); you can report or block any name.
