“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.”

“Not only did I discover how the foods I was eating affected my blood sugar, but I also came to see that I was most likely pre-diabetic. Ultimately, I lost about 50 lbs and have dramatically changed my mood and energy levels.”

FAQs

Who is the January app for?

Whether you’re trying to manage a specific health condition or just want to optimize your health, January can help anyone who wants to discover the intricacies of their body and use real-time data to support a healthier lifestyle.

What is included in a January plan?

When you sign up for a January plan, you’ll go through a quick telehealth evaluation so a licensed physician can determine if you are eligible for a continuous glucose monitor (CGM) prescription (most people are). If approved, you’ll receive a January Kit that includes one CGM, which you’ll use during the first 2 weeks of the app, and access to the January app. You’ll also need a compatible activity tracker. January is compatible with most popular activity trackers, including all Apple Watch models, Oura Ring Gen 2 and Gen 3, and all Fitbit trackers (except Ace 3).

What can I expect in my first month?

During the first two weeks, we’ll set up your wearable equipment and undergo the process of “training” January’s AI to help us understand your unique physiology. This training period is essential for a truly personalized experience! For the following two weeks after training, you’ll continue working to hit specific daily targets around the way you eat, move, and recharge — the basis of your journey toward complete metabolic health.

How does January estimate my glucose without a CGM?

Many data points contribute to our AI’s ability to estimate your glucose curve and project it two hours into the future, including heart rate data, food logging, activity level, and glucose. That’s why we require you to wear a CGM and activity tracker for the first 14 days in the app. This provides us with a large enough data sample to understand your body in a way that we can estimate your glucose curve, based on your activity and eating habits.

It’s not necessary, but some people like to recalibrate their AI every 3 months to keep the model consistent with their latest eating and exercise habits. For example, if you were to cut meat from your diet and exercise 25% more, that would be inconsistent with how we modeled your initial behavior. In cases like this, recalibrating the AI ensures the most accurate modeling over time.

How do I contact January?

You can contact us at support@january.ai or by calling us at (650) 275-4378. Someone from our team will be available to answer the phone 9 am - 5 pm PST, Monday through Friday. We will respond to all emails within 24 hours. We value any thoughts, concerns, or feedback you have!
