Updated phone and. Now not working … at all

Pretty much as the title says. I got a new phone and had to reinstall a lot of apps. It asked did I want to import old data (yes), but that’s about as far as it gets. It just hangs on a splash page.

Kinda sad.

Not sure what to do.

Update 10.9.26

Every supplemental dose I enter appears on the correcr day at first, but then duplicates itself when you open to enter a new supplemental dose the next day. Frustrating trying to keep up with what are the actual doses I entered.

Used to Love but it never works now

I used to love this app and had used it for years. Now it is always broken. I’m currently at the beach in Southern California and it is saying it won’t record a sun session because there is no vitamin d at 11:15 am which is crazy because it is at a 7. I’m
off to find a different app. Prior to this it was crashing every time I opened it for months. I’m tired of wanting to quickly log sun time and monitor d before sunscreen use and not having it work.

Random number generator

Over the past couple of weeks the app reported my D level has gone from 52 to 65 to 47, to 55. Supplement doses were duplicated, then mostly eliminated, then reappeared. The progress dials were displaying numbers that had nothing to do with my D level. For a long time this was a very stable and useful tool. Lab tests were generally pretty close to the predicted levels from the app. The Developer has attempted to address problems, but it seems as though he’s playing whack-a-mole with his code base.

Everyone should have this!

Did you know that Vitamin D is immunity boosting, anti-cancer and supports upper respiratory health?! Did you know that your body converts cholesterol in your blood through your skin via sunshine into Vitamin D that lasts 2-3 times longer than supplements?! This app helps you learn how to safely do this! Learn and Be Healthy! I give this app suggestion to all my patients!
