360-degree lifestyle and clinical tracking, along with sensor-free glucose predictions.
Four things it does that nothing else does together
Glucose predictions, with or without a CGM
Machine learning over millions of wearable, demographic, and user-reported data points, no sensor required.
An AI coach that knows the whole record
“What should I eat for breakfast with my metformin?” Answers grounded in medications, labs, and history.
Goals that adapt to real behavior
Adaptive micro-goals and proactive nudges tuned to what a person actually did this week.
It already knows the medication list
Because the coach sits on the same Health Context Engine clinicians use, it answers in the context of a person's actual labs, prescriptions, and history, not a generic wellness script.
What should I eat for breakfast with my metformin?
Metformin has been making me feel nauseous lately.
I’m going to Trader Joe’s today. Generate a grocery list.

Nothing in it is crowd-sourced
Grocery items, national brands, chain and local restaurant menus, and recipes, each entry verified rather than user-submitted. It is the difference between a log a clinician can read and a log they have to discount.

What changes when people can finally see the data
“A1C went from 6.3 to 5.1 in a year by following Jan's information. The weight loss was just a bonus. Jan helped me dial in my diet without giving up the foods I crave, spiking glucose, or blowing macros.”
“I have been looking for something to help me to stave off diabetes. This program is what I was looking for, several months before I found it.”
“I learned how to structure my eating to help my body respond better, especially increasing fiber significantly and intermittent fasting. Having the real-time data to see what did and didn't work was fantastic.”
“I am living so much better. My sleep and life continues to improve and I know I have control over my blood sugar management. I owe this to my January AI program and would recommend it.”
“Been using this app for about three months now. It's a great way to really see and make you aware of what you're putting in your body. So far I have dropped 18 pounds.”
“This app helps me learn the impact that food has on my sugar levels… which helps me make better decisions on the type of and quantity of foods I should be taking in… absolutely awesome!”
“I have been searching for an app like this that provides glucose index information instead of googling everything. This is fast and easy to use.”
“It's so easy and I use it to scan items when I'm grocery shopping. If I'm eating out then I take a photo of my food. It shows the ingredients and all the nutrition facts.”
“I have been using January for a few months and it has really helped me understand how the foods I eat affect my glucose levels.”
“The app is easy to use and the insights are actionable. I have changed my eating habits and lost weight without feeling deprived.”
“January has been a game changer for managing my prediabetes. The food logging is incredibly accurate and the predictions are surprisingly helpful.”
“I love that I can see how a meal will affect my glucose before I eat it. It makes dining out so much less stressful.”
“Finally, a health app that connects the dots between what I eat, how I sleep, and my labs. My doctor was impressed with the reports.”
“The coach feature keeps me accountable without being judgmental. I have learned more about nutrition in two months than in years of dieting.”
