Wonderful App
This app is the best for tracking all the important aspects of circadian rhythm to maintain a circadian lifestyle! I have been using it since it launched and it keeps getting better! Great job SKW!!!
Contact does not work….
Overall this app is stellar. Although, when attempting to make contact with developer no link works here.
Simple question: Does the app have ANY alarm clock functions, like wake up to see Sunrise, when UV-A & UV-B is available???
Please fix your links. The link gets you to a page, but no link works after that.

No idea what is going on with this app.
But there’s no way the max UVI is 5 here in Lagos today.
It would appear following this app will lead to getting burnt and quick!

🌞the LIGHT and the WAY🌞
Shout-out to Zaid Dahhaj who recommended this app!
A practical tool - the Swiss Army knife of sunlight tracking apps! Has all the necessities while keeping it simple.
Let this app guide you back into circadian alignment. Good health and longevity depends on it.
Do your own research, you’ll find we’ve been kept in the dark about the healing properties of the sun! Understand, the sun is to be respected and received in proper order. This app will enable you to abide by the sun in the right timing, dose and context.
This app is now my trusted daily companion! Gave the free trial a chance [the paid full access version] - its additional features are worth the expense if one can afford it. Like having the ability to log accumulated Vitamin D exposure within the app is helpful for someone with health issues, like me, who needs to monitor it closely over the coming months.
Sarah also provides important education thru her app, always more to learn. Check-out Zaid Dahhaj’s Solar Callus Guide to complement this app!
Consider, who is there for you everyday of your life…day after day without fail? Who nourishes the whole earth with its intelligent rays? Not a mystery, look up! Plain to see. Thanks and Praise to RA! The very LIGHT and The Way🙏🏽

An App I Didn’t know I needed!
I’m just beginning to learn about the importance of circadian rhythm so this handy little tool will be awesome to have!
Unexpectedly Useful
I’ve been implementing a lot of circadian aligned lifestyle changes since finding Sarah Kleiner and this app makes it so much easier to do. I know exactly when I need to get outside so I’m able to plan my mornings with ease and get the maximum benefit from the early sunlight. The app is visually pleasing, easy to use and includes pretty much every feature you could possibly need. I use it multiple times a day every single day.

Best app for circadian rhythm!
This app has been so helpful for me as I have been working on my high leptin levels. It lets me know when I should be outside in the morning and when it’s best to go outside for my midday sun! The Lux meter is AWESOME for finding the right balance of light at night!
Great tool for circadian alignment
The Lux meter is especially useful. I appreciate that you can also see the sunrise, sunset, and UV rise times a week ahead, too. Great app!
Light was the missing piece
I have serious histamine intolerance that I’ve been trying to manage for years. In the last year I noticed if I was on my phone too much in the mornings, I was destined for a flare up. Now, with the information from Sarah Kleiner I can see when UVA rays are available and I recently realized that getting UVA rays MAKES MY FLARE UP GO AWAY. Thanks to this app, I’m locked in on when and how to utilize light for my health. I can’t wait to try it out during winter to see how much Vitamin D I am getting as well. Love the app, and I highly recommend.

Best Sun Exposure and All Around Circadian App!
I’ve been using MyCircadian to track my Vitamin D/sun exposure to see how it affects my sleep and energy. The app is very user friendly and well designed. As a super visual person I like all the colors and easy to see exactly when UVB starts and ends and also when set rises and sets. There’s a free “Build your perfect quantum day” and other free videos so overall it’s just such a good app and now replaces the one I use to use. HIghly recommended!

Game Changer
Sarah knocked it out of the park with this one! This is my most used app, utilizing it several times a day. I’ve completely transformed my health by getting the right light at the right times of day. Thanks Sarah!
Works Great!
I love being able to look and know exactly when I should be outside.
Literally Life Changing
I was finding myself awake from 12-3 multiple nights a week and it felt like a slow death. Somehow I came across Sarah, her courses, and her app. So far I’ve only implemented the light suggestions using the app (makes it so easy) and I’m sleeping through the night again consistently. I can’t wait to start layering her other tips around nutrition, movement, etc!

Don’t want to be without this app!!! Incredible!!!!
This app (and Sarah’s classes) have a permanent spot on my iPhone!
I’m a mom of six little ones born in just eight years, and I’m in my 40s — so I don’t say this lightly:
Sarah’s circadian rhythm app and teachings have been life-changing.
During my last pregnancy, I had less inflammation, a healthy (and manageable) weight gain, and no digestive issues — plus more energy than I’ve had in years. Postpartum recovery was incredibly smooth, quick, and I lost all the baby weight within four weeks without forcing anything.
What’s surprised me most is how naturally my kids have joined in with the rhythms I’ve learned — and we haven’t had a sick visit in over a year.
If you’re wanting to improve hormones, energy, or truly get the most out of the good food you’re already eating… this isn’t just helpful — it’s foundational.

Love this app
Really enjoying using this app to help kick start my journey into circadian health.
Circadian Rhythm
This app has helped me be more intentional with getting the right kind of light from the sun at the optimal times for the best health benefits. I am still learning about UVB, UVA, and so much more…but it has helped me to track sunlight all throughout my day. Thank you for creating this app!
Best circadian app out there
A great, easy to use app that’s packed with information. I’ve tried a few of the others out there and this is definitely the best one!
Helpful and informative app
This app is nice and easy to start using, comes with plenty of explanation on what each section of the dashboard is for. I was amazed at the difference in lux levels between a bright fluorescent light and sunlight. It also has links to some good resources / information. I recommend getting the free guide to the perfect circadian day from the website to help understand the why and how to feel better paying attention to your light environment. I need this app in New Zealand as our UV index is very high in summer, so it’s often a matter of minutes between healthy sun and burning.
It works well and fast, it’s attractive visually, and it has a beautiful simple moon phase section.
I did not give it the 5th star because I found the format of the resources/articles/videos very difficult to navigate, they are on a scrolling carousel display, and I can’t keep up reading the title before it moves to the next. Just a list of links would be fine! It works fine, just hard to read. I also had trouble understanding that logging a sun session can only happen when there’s UV windows. Took a bit of time to work that out (that’s mostly user error).
These are VERY minor complaints, please do not let these stop you from downloading it.

A must-have for sunlight seekers, even on cloudy days! ☀️⛅️✨
As someone with very fair skin and a deep commitment to optimizing health naturally, MyCircadianApp has been an absolute game-changer. 🌞
The Vitamin D tool has especially blown me away! It gives me precise, personalized guidance for when and how long to be in the sun based on my skin type (I’m a Fitzpatrick Type I), UV index, cloud cover, and more. I live in a region with frequent overcast days, and I was always unsure whether I was actually absorbing any Vitamin D and now I finally have clarity! I also love that I can see exactly when the UVA & UVB windows are, and Sarah so beautifully explains the benefits of both types.
What I love most is how the app empowers me to:
• Get safe, effective sun exposure without burning
• Plan my outdoor time with intention and rhythm
• Align with my body’s natural light cycles in a way that feels nourishing and intuitive
It’s not just another tracker, it’s a wellness compass. 💛
I feel more energized, more aligned, and more informed than ever before. Grateful for this tool, and highly recommend it to anyone wanting to build a deeper relationship with the sun and their circadian rhythm.

Life Changing Simplicity of a Sunlight App
I started using Sarah’s MyCircadian app in November 2024 after months of unexplained fatigue that no medical advice could shift. Within three weeks of following the app’s daily sunlight guidance, I felt like myself again, clear-headed, energised and hopeful.
The app’s intuitive sun session timer and real-time UV tracking helped me get outside at the right time, every day and supported me eating within daylight hours. It wasn’t just about vitamin D, it was about syncing with nature in a way that finally made sense to my body. My daughter is following my leads to & it has helped her immensely.
I now use it daily and recommend it to everyone, especially alongside Sarah Kleiner’s podcast and resources. Her insights into circadian biology gave me the tools to take control of my health when nothing else worked. The support team has been incredibly responsive and genuinely caring, making the whole experience even more empowering.
This app didn’t just help boost my health, it helped me restore something I didn’t realise I’d lost. I’ve rediscovered my love for being outside in the sun, without fear. I’d forgotten how good felt.
Thank you
