Now all of my info is sitting in the pending area and it will not go through and I keep getting errors. I also am not able to use the “contact us” section on the app for the reporting the issue as I am getting errors . ### 3/5 — Latest update *2026-01-30, version 7.5.24* Your latest update erased all my streaks. Starting from zero again ### 3/5 — Warning. *2025-07-04, version 7.5.16* You are to enter sensitive data such as income and email address to activate. Inappropriate data scraping. ### 3/5 — Utilisation compliquée *2025-03-09, version 7.5.14* L’application n’est pas simple d’utilisation. Ce serait bien de pouvoir consulter et modifier ce que l’on enregistre comme nourriture car si on se trompe cela affecte l’analyse des données. Si vous n’avez pas de réseau ça n’enregistre pas forcément non plus. ### 4/5 — Good but needs some work *2025-03-02, version 7.5.13* The app is really useful to have an idea about what you eat and when you eat it. However every 2/3rd adding of water and food seems to not go through to the servers. Overall good, but still needs improvements. ### 3/5 — Please *2025-02-14, version 7.5.13* Add feature to get informations about sleep, walking or other things from Apple Health ### 3/5 — buggy and design flaws *2024-11-14, version 7.5.12* Aside from the frequent connection/server errors, it is missing the ability to edit and delete logged items. Still in my first 14 days, so perhaps those abilities are being activated later. It is also missing a way to quantify the food/beverage items. Even with those massive shortcomings, it is still worthwhile logging everything :-) ### 3/5 — Why?? *2024-11-07, version 7.5.12* If this picks up steps from iOS Health then why can't it read all the other data like exercise that is logged? Having to manually input this stuff is stupid. ### 2/5 — Doing too much *2024-10-26, version 7.5.11* This app is just a free way for you guys to collect data with out paying focus groups. What’s this app for? I came here because of Huberman to track my fasting time. Why are you asking about my specific foods? There’s no calories tracker next to it? Sleep: I don’t like the dial. I wake up to input my sleep and it’s for tonight. There’s no option to back chart. ### 3/5 — Use apple health more. *2024-08-30, version 7.5.10* My apple health has all my nutrition, activity, and good sleep tracking, my medications and so much more. But I’m only asked to share my step count and that is nice as a minimum. Now I have to put it all in again for this app. I want the benefit so I eventually will. But I know apple health will let me share it with you if you would just ask. There’s history too. This is just going to be a slower start than I hoped. ### 2/5 — App is not working properly *2024-06-10, version 7.5.8* When adding food or water, it says network connection problem or unexpected problems. What is this? :( I wanted to use this app ### 3/5 — Can’t register *2024-05-13, version 7.5.6* Not able to receive an activation code and register for an account for some reason. On iOS 17.4.1 ### 1/5 — Problemi *2024-05-13, version 7.5.6* La app ha smesso di funzionare dopo due settimane. L ho disistallata e reistallata ma non riesco ad accedervi o registrarmi nuovamente. Si perde solo tempo. ### 1/5 — Can’t Successfully Create an Account *2024-05-13, version 7.5.6* After hearing Pam Taub speak about the program last week at Rancho La Puerta, I couldn’t wait to download this app and begin. Unfortunately, after answering all of the required questions to set up an account and entering my email address, nothing happened when I clicked submit. I also checked my email (junk folder too) to confirm that no code was received as well. My husband is encountering the same issue on his phone. Is this app still functioning? Please help! ### 3/5 — Great app just needs some issues fixing *2024-04-13, version 7.5.5* hello, I like this app but there are a few things on it that keep freezing or not loading like going to the sleep page. I changed my eating times too and it still sends the old time notification which is a little silly. I also thought though that it would be good to have a reminder alert an hour (or any chosen time) before the end of the eating cycle. I’m pretty good at the moment for being somewhat on time to finish meals but occasionally I forget and think that it would be good to have that reminder. finally, it looks like I can’t send this message on the app so I will try to send some other way. thanks, keep up the great work it’s been a great help. ### 1/5 — Doesnt work *2024-04-06, version 7.5.5* I cant save items , it doesnt work. ### 1/5 — Gave up after a few day! *2024-03-24, version 7.5.5* App didn’t record sleep using the ‘log now’ on several days. Recorded meditation incorrectly. HATE logging 1 med at a time. Unfortunately this is a poor app for long term use. If the app was improved they would get so much more accurate data for research. Unfortunate! Goodbye. ### 1/5 — Loved the Book HATE THE APP *2024-02-27, version 7.5.4* It is impossible to easily navigate backwards if you live a busy life and cannot log everything real time. ### 1/5 — Not working *2024-02-25, version 7.5.4* I like the book. I downloaded the app to log my meals ans see a summary of my meals-window after two weeks. The meals are not saved (stays in pending), sleep and activity does not sync. All that together = i have no real data here, how it can be used for a research purposes? I can’t receive any summary so the app failed the job. ## Most critical reviews (10 lowest-rated) ### 1/5 — No value *2026-08-04, version 7.5.30* I had high hopes for this app as I listened to The Circadian Code audiobook. Sadly, the app is an abandoned failure. Enter all the data you want, but you won’t get reports or support. Guessing Dr. Panda paid an intern to create the app and the intern is long gone. ### 1/5 — Very Buggy/Unusable *2026-01-31, version 7.5.24* This app is a great idea and comes from a book supposedly written by the app creator, that has some really good ideas and concepts. The app, however, doesn't generate reports. You get error codes instead. There's also no way to access or download the data. Hence, no workaround. On top of that, about 60 days worth of data just got deleted, going by my "streak" which just reset to 0, despite my using the app daily for about half a year. You'd think the doctor might spend a fraction of his royalties on getting a proper app made. ### 1/5 — Glitchy *2025-05-21, version 7.5.16* Recorded all info for 15 day baseline and it was unable to upload information - will be moving on to something else. Do appreciate the blog info but the app doesn’t function. ### 1/5 — Needs Improvement *2025-05-14, version 7.5.16* Surprised that coming out of the Salk Institute this app would be so archaic and not user friendly. I’m sensitive to nnEMFs yet using this app forces me to connect to the Internet for every activity logged. Oura Apple Garmen and several other tracking devices record and store data and allow the user to log data while not connected to Bluetooth, WiFi or cellular data. This is a non negotiable for me, having to wake up turn on my WiFi and stare at blue light from the screen before I get outside for sunrise? This app would make me more sick! ### 1/5 — Bug? *2025-01-24, version 7.5.13* I am reading the book and would be very glad to use the app! Unfortunately I cannot sign up, no e-mail is being sent with a registration code when I get to that step. ### 1/5 — Bugs and errors *2024-08-19, version 7.5.9* This app doesn’t work at all- I entered my data for 15 days straight and then it wiped it all away and started from 0 again. I guess the app is not being kept up to date. Don’t waste your time- love the concept but the app authors should remove the app from the App Store if app is no longer functional! Half the features don’t work properly including the message support feature! I tried to write them and tell them some features weren’t working but the message would not send. The sleep feature doesn’t save the accurate time you enter which is one of the main reasons to use the app. You also can’t enter multiple sleep sessions for the same day- eg if you had broken sleep or if you had a nap. ### 1/5 — Bugs, Built-in Reporting System Broken *2024-07-31* In addition to fiddling with the bug I describe below, I also took the time to write the following report from the apps built in “contact us” method. When I tried to submit it, I repeatedly got an error message saying to try again later. In general this app has been frustrating to navigate. As a personal developer myself, it feels thrown together. Here’s the bug description I tired to submit: “The app has a bug on iPhone were we cannot always log sleep in arrears. Even for correctly entered dates and times, the app incorrectly reports that the start time must be before the end time. We also cannot use the circular slider on the app to input time in arrears, as the app will wildly jump 3-4 days ahead if the start slider passes over 12 AM. Very annoying bug! Also, is there a good reason the text boxes in this application don’t allow for the typical aids, such as automatically starting sentences with capital letters, etc?” I expected more as I know Dr. Pandas lab behind the research is widely acclaimed. ### 1/5 — Horrible waste of time *2024-06-05* The app acts like it’s operating, but it’s not. All the food entries ended up as pending items even though the message was received that synch was successful. The days counted up to 15 but the Clock and Reports didn’t generate. Instead a message was received that the information wouldn’t be available until the baseline history was entered. The baseline is supposed to be 14 days so that’s a bug. I don’t know how other people have gotten any value from this app. I read the book and thought as much effort went into the software as the book itself. There’s no value to this app at all because you can’t even review your entries for the baseline period. It’s a complete waste of time. You’re better off with a pen and paper. ### 1/5 — Unresponsive *2024-05-15, version 7.5.6* Signed up, never got a confirmation email to verify. Doesn’t seem to be managed. ### 1/5 — Useless - can’t complete account set up *2024-05-14, version 7.5.6* When I get to enter email stage the app won’t let me complete set up. Very frustrating as I read the book and as looking forward to using the app. Doesn’t look like any meaningful app support available either to report the issue to ## Most praised reviews (10 highest-rated) ### 5/5 — L’application est super pour vous rappeler les concepts du rythme Circadian *2024-05-12, version 7.5.6* Super application ! Je l’adore ! ### 5/5 — Great resource! *2023-10-04, version 7.5.0* This is a very simple and effective app with a fun look. I love the blog section, which helps me learn more about my health and motivates me to stay on track for my goals. Tracking food and sleep is easier with the app’s reminders and it is more in depth than other apps I’ve used. ### 5/5 — Good app with great function *2023-09-28, version 7.4* I use the app to track my calories and it helps a lot in my journey to lose weight! ### 5/5 — Easy science based health tracker *2023-09-28, version 7.4* This is a simple and easy to use health tracker. I like that the data is anonymous and goes to help science at a reputable institution rather than other apps that sell your data to random companies. Other reviews said the app was buggy or slow, but I haven’t experienced that at all. The new updates must have fixed it ### 5/5 — Healthy lifestyle *2023-09-28, version 7.4* T This app is amazing, very easy to use! My eating window and food choices are in check everyday. I highly recommend this tool if you are ready to make your health a priority! ### 5/5 — A great app! *2023-09-27* Since I started using this app I can honestly say I have been thoroughly enjoying it. There are reviews that talk about the lag of the app but, since they seem to be a bit older I thought I’d give up updated claim: IT WORKS GREAT!! I love knowing that I’m contributing to an active research project aimed to enrich lives of everyone in the world. I definitely would recommend this app for anyone that is interested in leading healthier lifestyle AND learning why it improves health outcomes. **Developer response:** We're delighted to hear that you're enjoying the app and that you've had a positive experience with it! We admire your appreciation for the research and its potential to enhance lives. Your recommendation is a valuable insight for potential users. Thank you for your valuable feedback! ### 5/5 — Awesome app! *2023-09-25, version 7.4* Great tool to track my eating window. This app helped me to achieve my health goals and I highly recommend it! ### 5/5 — This Method Works *2023-06-15, version 7.2* I’ve been using this app for almost 3 months. The first ten days was the adjusting period but after that I noticed that I was more aware of what I am going to eat and how much. I went to bed earlier and have more energy. I weight myself every day and it slowly coming down which is good. I think I’ll continue to use it. ### 5/5 — Not working properly *2022-12-22, version 5.5.7* Can’t register. There’s a bug that doesn’t let you fill in the mail address and then says you’ve already registered. You never receive the mail or anything though - you just can’t get past ### 5/5 — Thank you. *2022-06-18, version 5.5.7* I have been using the app for around 11 days now. Early days but just the process of recording my health data over that time has had a beneficial impact on my awareness and actions. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
