Best circadian app!

I absolutely love this app! It has completely changed my awareness of light and optimizing my time outdoors for the best benefits. I love the reminders and how they adjust to the correct time when I travel. Plus, it’s easy to use and they have excellent customer service whenever I’ve had a question. Highly recommend this one!!

updates??

this app would be amazing if I didn’t have to constantly change the location back and forth to where I live so the times are correct, it doesn’t update on its own otherwise and keeps telling me the wrong times which is honestly frustrating

Very inaccurate

Currently the app shows the sunrise at 06:11 in Brighton , UK , however all other apps indicate the sunrise at 06:32. And many other inconsistencies.

Times not accurate

I don’t look at Circadian every day, but today I noticed it has the wrong times for sunrise and sunset. Example: app says sunset is 7:24, while real sunset time is 7:50.

I double checked the city it is set at and the date and time of day and those are all accurate.

What happened???
If it doesn’t know the correct sunrise and sunset times, how can any of the other times be accurate?

Love this

Love this app and cannot explain it enough! Knowing the times of everything makes holding my rhythm so easy. Use this everyday!

Love this app!

Great customer service! I have sent getting notifications when I first got the app so wrote an email. Got a very speedy response with the exact info to change my settings so I would.
Being able to have reminders to get out at sunrise, get more light and to optimize sunlight and re establish a healthier circadian rhythm is changing my health and mood. Very much appreciate all the information available as well. Thanks! Highly recommended.

Times aren’t correct

I rely on this app but recently the times have been way off. I’m getting alerts for things like sunrise and sunset - but not at the actual times of those. Maybe it’s a bug or glitch??

So Helpful

I love this app. It’s so easy to use. My favourite thing is I can set notifications for times like sunrise or uva rise so I remember to go outside to get light in my eyes.

LOVE THIS APP

Such a helpful, easy to use app. As someone trying to be mindful of my circadian rhythm who tries to get natural light exposure at the best times of day, I just love it. All the lighting info for any given day that I need in one place, even laid out in a helpful visual format. Seriously thank you for this app!! 🙌🏼

Accuracy Declining

I used to love this app but now the times are off for sunrise which makes me think I can’t trust any of the other times and makes the whole app useless. Not sure if this is a bug or if the app no longer has support. Would love to see a fix.

Live by the sun cycle

This app is so helpful - not just for tracking the light/dark cycles and sunset/sunrise—but it also explains WHY it’s important to live by our circadian rhythms in simple terms. This app offers notifications that are super customisable—and a beautiful + intuitive visualisation of the precise rhythm of your day, exactly tailored for where you live. It’s also excellent for those who want to catch as many “golden hour” sunrises/sunsets as possible. The yearly subscription is (actually!) quite reasonable, and it’s such a reliable + useful app, I’ve renewed for 4 years in a row.

Sunrise & Sunset Times Off by 25 Minutes

The app is great overall, but the times for sunrise and sunset aren’t changing each day and are off now at my location by 26 and 24 minutes, respectively. That is a significant difference, and it needs to be fixed.

You want this App!

I love this Circadian app. It’s easy to use, helps me stay on track with healing light exposure and has an affordable lifetime plan. Customer service has been excellent anytime I’ve had a small issue or question. Highly recommend.

Good info

The best and so simple

Love the simplicity of this app. So good to get the daily reminders

No choices on notifications

This app used to allow a choice of which 3 notifications a day you are allowed. Now the free choices gives you times that make no sense like when to exercise. You cannot get a notification when it’s sunrise or sunset on the free version. Waste of time.

Notifications?

All of a sudden the notifications don’t work. I’ve done everything I can think of to get them working again, but none of it has worked.

Not getting notifications

Idk why but all of a sudden this app won’t send me notifications anymore. I tried to keep the app open to see if that was the problem and it’s still having the same issue.

Sunrise / Sunset times inaccurate

The sunrise and sunset times have been stuck on the same time for about two weeks. I’ve had this app for over a year and this happens constantly. Please fix it already…

Perfect

Love this app. Helps me plan my day and be more productive, and never miss a sun rise.
