About this app

My Circadian Clock.
The My circadian clock app is for use in research studies examining how diet, exercise, and sleep affect health. Our body contains circadian (circa – approximately and dian – day) or 24 h clocks that influences the timing of sleep, hunger, metabolism, and physical ability. Research studies run in different locations are trying to understand the interaction between “how much” and “when” we sleep, eat, or exercise for better health. You need an activation code from these research studies to download and use the app.
Following are the key features:
Camera function to snap picture of everything you eat or drink
Sleep tab to record time to bed and time of waking up, and sleep quality
Exercise tab to log physical activity
Food and Beverage tab to log all dietary intake including an autofill option to add frequently eating items easily
Water tab to log water
Health tab to log and monitor health parameters
Medication reminders to track your medicine/ supplement intake
Contact the research coordinator for any questions/ help.
Blogs tab to read scientific blogs on various topics like food, nutrition, sleep, time-restricted eating, etc.
Additional Features:
Health Tracking : Now you can track your results for a wide variety of vitals and blood tests. You can now also log in metric units.
Daily tracking and study status info on the home page : With a quick glance at the homepage, you can see when you ate that day, step counts, last night’s sleep duration, and where you are in the study.
Step Counts : Now you can view your step counts from Google Fit/ Apple Health in the app.
Notifications are used to provide health tips and reminders.
Settings : You can set your eating, sleeping, and exercise targets in one place. You can also set reminders for sleep, medicine, and water, eating window start and end notifications from the settings page.
Meditation tracking.
Improved user experience : The myCircadianClock app has been redesigned to make it easier and more enjoyable to use.

Ratings and reviews

I hope you aren't actually using data for research. There are too many issues with the app. I am on day 3 for the baseline, but some how it erased day one and says im on day 2. You cant tell if its synching to Google fit. Taking pictures is hit or miss. It just spins while I sit and watch my food get cold. I'm not sure if eveything even saves, because there is no history. Sometimes there is a dot on the time line (which is too small to be useful) and sometimes not. Perhaps this app is really for research on patience? I give up and am uninstalling.

I'm still in the 2 week base line period so I have yet to see how things work after that, and I love the guide to help get you set up and understand the study, but the data is going to be misleading for 2 reasons. 1: You can't edit food entries once saved so mistakes can't be corrected. 2: The editing feature for sleep is faulty - even if you enter sleep for a different day/time than what already exists, it thinks you're trying to replace it and seems to have issues recognizing the differences.

As stated by most of the other reviews, I am severely disappointed by this application. I watched the TedTalk that mentioned this app and was super excited to try it, for myself and to contribute to research. However, the interface is simply unusable and infuriating. This application must be completely redesigned or majorly improved if you hope to receive data from your users. I recommend modeling it after an app like MyFitnessPal. The interface is simple and user-friendly, you can look back on your input history, and receive instant results. I completed the two-week baseline period for My Circadian Clock and was hoping the app would work better after I was finished but it does not. I am uninstalling the application with the hope that it will be greatly improved and I can redownload it at a later date.
