A personal sun-time estimate from the live UV index, your skin type and SPF, with flip and reapply reminders. Now with a redesigned, quicker setup.
Plan your time in the sun around the live UV index. SunDose turns real-time UV data, your skin type and your SPF into a personal sun-time estimate, then reminds you when to flip, reapply sunscreen or take a break in the shade.
YOUR PERSONAL SUN-TIME ESTIMATE
Start a tanning session and SunDose suggests a duration based on the current UV index, your skin type and the SPF you are wearing. The session timer keeps track for you, with reminders to flip, reapply or head into the shade, so you can relax and enjoy the sun.
LIVE UV INDEX & FORECAST
See the UV index for your exact location right now, plus hourly and weekly UV forecasts and cloud cover. Spot the peak UV hours at a glance and plan your beach day, sunbathing or time outdoors around real data.
ROUTINES MADE FOR YOU
Get a daily sun care routine tailored to your profile and tanning goals, from sunscreen to after-sun care. Log every session and keep a photo diary of your tan.
WATER REMINDERS
Warm days call for more water. Fill the visual bottle with quick-add buttons and get friendly reminders to drink throughout the day.
LIVE ACTIVITY & DYNAMIC ISLAND
Your session timer stays on the Lock Screen and in the Dynamic Island. See the time left and the UV level, then pause or end the session with one tap, without unlocking your iPhone.
HOME SCREEN WIDGETS
Today's UV index, water progress, tanning streak and SPF reminders right on your Home Screen, in several widget sizes.
YOUR TAN JOURNEY
Session history, weekly sun time, streaks and your tan progress over time, all in one place.
GOOD TO KNOW
SunDose provides general guidance, not medical advice. Sun-time estimates are based on the UV index and the skin type you choose, and every skin is different. Always use sunscreen, and check with a doctor or dermatologist if you have questions about your skin.

this app is great it gives you a good routine but the timer counts by minutes of five so if you need to tan for 7 minutes you would have to set a different timer. i also don't like that the timer doesn't beep when the time is up. besides that this app is great!
Developer Response
Thank you for the feedback! Both points are valid, custom minute input (not just 5-min steps) and a sound and haptic when the timer ends are coming in the next update. Appreciate you taking the time to write this 🌞
