Want to build a healthy sunbathing routine and get the best tan at the beach or at home?
Sun’n’Chill is your personal guide. Plan your beach sunbathing routine, find the best SPF for sunbathing and learn how long to stay in the sun safely-all with one app.
. Build your beach sunbathing routine: schedule tanning sessions around the hourly UV forecast. Whether you’re on the sand, in the mountains or relaxing in the garden, you’ll know the best time to sunbathe.
. Smart timer shows how long to stay in the sun: the app calculates exactly how long to tan in the sun based on your skin type, sunscreen SPF and real‑time UV index. It alerts you before you reach your limit so you can avoid sunburn.
. Find the best SPF for sunbathing: enter your sunscreen’s SPF and Sun’n’Chill will tell you if it’s strong enough for the current UV level, helping you choose the right protection.
. Encourages healthy sunbathing habits: track total exposure across the day and follow tips that promote healthy sunbathing habits-stay hydrated, rest in the shade and reapply sunscreen.
. Accurate UV index and safe tanning range: GPS‑powered UV readings show when the sun is gentle (UV 4-6) for tanning and warn you when UV is too strong.
. Personalised settings: pick your Fitzpatrick skin type, add sunscreen and reflective surface details, and let the app tailor its recommendations to you.
