User Reviews

Users praise Circadian for helping manage daily light exposure and rhythm with a clean, intuitive interface and customizable reminders. However, recurring issues with time updates, auto-location, and notification reliability undermine trust. Sunrise/sunset times may be wrong or stuck, and some users must open the app to refresh data. The app remains valuable for many with strong support and reasonable pricing, but ongoing fixes to time sync, location updates, and notifications are essential for broader satisfaction.

Pros

Helps maintain circadian rhythm with clear guidance on light exposure and daily times.
Easy to use with a clean, visually appealing interface.
Customizable reminders/notifications for sunrise, daylight, and other key times.
All-in-one source for lighting information for your day based on your location.
Responsive customer support and generally good value (affordable subscription options).

Cons

Sunrise/sunset times often do not update and can be wrong or get stuck, undermining trust.
Auto-location doesn’t reliably update; many users must manually set location or refresh data.
Notifications sometimes stop working or fail to trigger as expected.
Occasional crashes/force closes reported by users.

Recent reviews

I used to love this app but not really sure what the point is to have an app (that I pay a subscription fee for) to notify me at different times of the day… when I have to go in every day to turn off location services and turn them back on for it to update to the correct times. I may as well just google the info every day. This hasn’t worked properly for a very long time. Contacted the developers early this year and they told me a fix would be in place sometime in March. It is now August and still doesn’t work. I have done every app update. I have deleted the app and reinstalled it. Multiple times. Not renewing my subscription. What a waste of money this year.

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!!
