About this app

UV INDEX TANNING TIMER

Sunkat is the UV tanning app for people who actually want a tan. It reads the live UV index for your exact location, factors in your skin type and the SPF you are wearing, and builds a tanning session around today's sun - how long to stay out, when to flip, and when to get out before you burn.

No selfie scan. No scare tactics. Open Sunkat, enter your details, and your tanning routine is ready in under 30 seconds.

UV INDEX FORECAST, HOUR BY HOUR

The UV index changes all day, and any tanning timer that ignores it is guessing. UV tanning means tanning to the number, not to the clock. Sunkat pulls a real-time UV index reading for your location plus an hourly UV forecast for the rest of the day, adjusted for cloud cover, so the UV number you see is the UV you are actually standing in. Watch the UV index climb toward the midday peak, see the best time to tan marked out for you, and plan your sun around real UV data instead of how hot it feels.

A UV TANNING TIMER THAT KNOWS THE SUN

Your phone's alarm doesn't know it's UV 9 outside. The Sunkat UV tanning timer does. Start a session and it counts down the exact tanning time your skin can take at the current UV index, then tells you when to flip so your tan comes out even instead of streaky. Flip reminders are loud and work with the screen off, so you can put the phone down and actually lie in the sun. A sunbed or tanning bed session works the same way as the beach.

SKIN TYPE, SPF AND SUNBURN

Sunburn is what ruins a tan, not the sun. Sunkat asks for your skin type once and uses it in every calculation, because a fair skin type burns in a fraction of the time a darker one does at the same UV index. Add the SPF of the sunscreen you are wearing and your safe tanning window stretches accordingly - no sunscreen at all and it shrinks. Sunkat is a sunburn tracker as much as a tanning tracker: it is watching the line you should not cross. The result is a sunburn you do not get and a tan you do - no self tanner, no bronzer, no fake glow, just real sun tanning.

TAN TRACKER AND SESSION HISTORY

Every session is logged, so Sunkat doubles as a tan tracker and keeps your tanning routine honest. See how much sun you got this week, what the UV index was when you got it, and keep a streak going all summer. Short consistent sessions build a deeper tan than one long burn, and a tan tracker is how you stay consistent. Most people quit their tan because they lose track of it - a tanning tracker fixes that.

FOR EVERYONE OUT IN THE SUN

Sunkat started as a tanning app, but the UV index it runs on is the same number a runner, a cyclist, a gardener or a parent at the playground needs. If you are outside for hours, check the UV forecast before you go, take sun protection seriously when the index is high, and let Sunkat tell you when the sun has had enough of you. Sunbathing, hiking, a long lunch outdoors, a day at the pool - it is all UV exposure and it all adds up.

MADE FOR REAL TANNERS

Most UV index apps are built for people who are scared of the sun. Sunkat is built for people who love it. There is a difference between burning and tanning, and Sunkat keeps you on the right side of it - at the beach, in the garden, by the pool, or on a sunbed in February. No lectures, just a smarter way to tan.

If you have ever set a phone timer and hoped for the best, this is the tanning app you actually needed. Your tan. Your rules.
