Pretty app, can’t start without “scanning”, obsolete gender concepts

Look I don’t have time to aim my phone at the sun to start this. SunDay is pretty, but I just want a ballpark based off the UV index. Starting this is just too hard.

And just two genders? How quaint. You’re forced to pick the “girl” or “boy” avatar with stereotypical clothing and hair. Gross.

Loses data

I really wanted to love SunDay. Looks good and all. Plus the camera looking at the sun to determine the UV index. But then losing my data is a no no. I have two users. I was in the sun first recorded my data, I saw it in the chart. Second user went into the sun, record was fine. Went back to my profile to find all my data was wiped.

For white skin only

I was excited to use this but I can only set my profile to a little white girl. How do I know the calculations are correct? Y’all didn’t include any brown people in your research. Fail

Only works half the time

I love SunDay when it’s working, but at least half the time I try to use it, after I do the sun snapshot, it goes to a blank screen and won’t load. Very annoying.

Sessions not visible

Every week or two I need to redownload SunDay because the upcoming sessions screen will not load.
Decent app overall, just a bug that needs to be addressed

If only it had Apple Health support

SunDay would literally be perfect if it automatically linked to Apple health and uploaded your vitamin D intake. I would get the this app necklace for sure if everything just worked together seamlessly; the necklace tracks my vitamin D intake, SunDay logs it, and my Apple health stores the results for me to view all my nutritional and medical information in one place. Other than that I love the UI interface and easy use of SunDay .

Absolutely LOVE this app!

I don’t usually leave reviews, but SunDay deserves it. From the moment I downloaded it, I was blown away by how easy it is to use and how smoothly it works. Everything is designed perfectly no annoying ads, no glitches, just pure convenience.
The best part? It saves me SO much time and makes my day way easier. Every feature feels like it was made just for me. And it’s not just me even my mom uses SunDay all the time! She’s always telling me how much it helps her stay organized and how simple it is to use. If both me and my mom love it, you KNOW it’s something special.
Trust me, once you try it, you’ll wonder how you ever lived without it. I’ve already recommended it to all my friends, and they’re hooked too. Don’t wait download it now and thank me later!

Greatest of getting D

I ve tried I think all of them in App Store ! But this is by far the best and easiest and believe the most accurate . You will not be disappointed in any way.

Easy to use

Quick pic and gives a good idea of how long you need to really be in the sun without protection. Not long at all. Reminds me to get out in the sun as well. Sun is often forgotten when I’m working all day in a building.

LOVE IT !

SunDay made my life so much easier ! Also downloaded for my kids too, it’s very easy to use

Such a Fantastic app.

Really Timely also, execution is well laid out, pretty easy.
