Im really liking the app and for that reason 5 stars. (I'm confused about calculating the exposure though, e.g., it says wearing a bikini is 80% exposed... But if I'm lying down, in a bikini (80%) only the top half of me is exposed to the sun (being 40%?!) And I cover my face usually, taking it down to 35%...! In a bikini lying down is it 80%? How? half my body 50% minus the bikini (say 5%) doesn't make 80. Arggh!!! However, the app itself works well and I really like the features. The timer. The logs. And the solar noon reminder are all great! Recommended. I just wish I could more accurately assess the %
Constantly crashes on manual entries or completing a sun session. Sent in app feedback and crash logs. No response from developer. Would love the ability to manually adjust the uv index value or the vitamin D IU per minute value. This would allow me to track my Sperti Vitamin D lamp usage.
This is the most important app on Google Play! Vitamin D helps with the immune system, bones, ligaments, tendons, muscles, joints, etc. *UVB from the SUN which interacts with cholesterol in your skin eventually makes the active form of vitamin D calcitriol which is sulfated. *Vitamin D from the SUN is the only vitamin D that the body utilizes efficiently for positive health benefits. Vitamin D Supplements eventually suppress the immune system and can NEVER be sulfated.!.
there is a serious bug from the very beginning. I recommended this app to my mother and she can't get past inputing her birthday. the pop up calender doesn't let you override with text. she's 70 years old. is she supposed to hit the back key 840 times to get to get birthday? absolutely ridiculous.
Update: still an amazing app to have, but I haven't seen this app improve in a long time. Not that it needs to bit sync would definitely be appreciated or at least a way to import/export data. Is the only app on the Google store that measures your vitamin D. And comes highly recommend by Dr Mercola himself. Needs back up, but the developer promise he'll add it soon. So definitely a bargain price, for a revolutionary tool that you can't find anywhere else.
It's great at calculating the amount of vitamin d. The burn warning used to make a sound and now it's not so now I have to keep checking for the warning. Otherwise great app.
Another pass at fix for the date of birth field not coming up on newer phones: 6P and Pixel.
