A smarter tan

Tanning, with a plan

Round-by-round timing

Sessions split into rounds with a cue to flip, so each side gets even sun and no part of you quietly overcooks.

Tuned to your skin

Your skin type sets how fast you burn, so the session length and reminders are calculated for you, not a generic timer.

UV aware, live

The plan adapts to the real UV index. On a strong day the session shortens automatically so a tan never tips into a burn.

Tips

How to tan without burning

Build it up, do not blast it

A tan develops over days. Short, repeated sessions give deeper, longer-lasting color than one marathon that ends in a peel.

Turn, so the sun is even

Rotate through front and back in timed rounds. Even exposure looks better and keeps any one area from burning while the rest catches up.

Keep sunscreen on

Sunscreen slows burning without blocking a tan. Sunly factors your SPF into the timing and reminds you to reapply during the session.

Stop when Sunly says stop

The moment your safe window closes, the session ends. A burn does not deepen a tan, it just damages skin and forces a break.

Frequently asked questions

Can you really tan safely?

You can tan more safely by building color gradually and never crossing into a burn. A tan is the skin's response to UV, so there is no completely risk-free tan, but Sunly keeps each session inside your skin's safe window and stops you before you overdo it.

How does the tanning timer work?

You set your tan target, session length, and the product you are using. Sunly then splits the session into rounds with timing for each side and watches the live UV, so exposure stays even and controlled instead of one long unmonitored stretch.

Does it adapt to my skin type?

Yes. Your skin type sets how quickly you burn, so Sunly tunes the session length and reminders to you. Fair skin gets shorter, more cautious sessions, while deeper skin tones get longer windows.

Should I still wear sunscreen while tanning?

Yes. Sunscreen slows burning without stopping a tan, and Sunly factors your SPF into the timing and reminds you to reapply. Tanning without protection is how a session turns into a burn.
