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 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).
