☀️ START AN ACTIVE EXPOSURE SESSION

Begin a tanning session with a single tap. Once started, SunTanApp runs a continuous exposure timer that tracks your real-time sun exposure and cumulative UV dose.

During an active session, the app continues tracking even if your screen is off or the app is in the background, so your progress stays accurate while you're enjoying the sun.

An ongoing notification clearly shows that your session is active and lets you return to or stop it at any time.

Ratings and reviews

Has the potential to be great. I love the UV ratings based on location. I like the timer and the suggestions based on skin type and SPF covering how long to sit on each side. However, the input options bug out constantly. I can't put an SPF rating of 30 then set target each side as it is stuck at zero. UI is not very userfriendly and I also do not like the microwave sound for when the timer is up, as although it's funny, it's far too short and I've had to set phone alarms incase I missed it.

Fine! Exactly what I was looking for! Selection of a menu by kcal, simple recipes and a ready-made list of products for the whole week! You don’t have to write out the products from each day yourself, summarize them and then just slap them into the store! With proper nutrition, the result will not be long in cọming - I have already lost weight quite well

it has potential but some stuff isn't intuitive. Why does increasing your SPF lower the exposure time? You do see why this doesn't make sense right? Another problem I have is there's no way to reset or adjust the time left.
