The comparison between Vively and January Ai, the differences, pros and cons.

Key Takeaways:

• Glucose monitoring approach: January AI focuses on predictive modelling that can estimate glucose responses even without wearing a CGM, while Vively centres on real-time glucose monitoring with a CGM sensor inside the Vively app.
• Target audience: January AI tends to speak most directly to people using glucose insights for food choices and weight goals, while Vively supports a broader set of metabolic health goals, from weight management to PCOS and menopause support.
• Holistic health management: Vively combines glucose data with lifestyle tracking across meals, movement, sleep, and stress, plus optional dietitian-led support. January AI is more app-led and self-directed, with insights generated through its models and logged lifestyle inputs.

What is Vively Health and January AI?

Vively and January AI are both subscription-style platforms focused on metabolic health, but they take different routes to help you learn from glucose data.

January AI is best known for its glucose prediction technology. The app can estimate glucose impact from meals and lifestyle inputs, and it can be used without wearing a CGM, depending on how you choose to engage with the platform.

Vively is built around real-time CGM data, using continuous monitoring to help you see what your glucose is doing throughout the day and connect those patterns back to your habits. The experience is designed to help you learn what influences your glucose most, then translate that into realistic changes you can actually maintain.

Both tools aim to support informed decision-making around metabolic health. The biggest difference is how they generate insight: January AI leans on prediction and modelling, while Vively prioritises live, in-the-moment feedback from a CGM.

January AI

January AI is a US-based company. It has expanded its app access, but CGM supply and program availability can be limited by region and the company’s approved service areas.

January AI’s core promise is prediction. Instead of relying on continuous wear for everyone, it uses an AI-driven model to forecast how foods and habits may affect glucose. TIME has described the product as predicting how much a food may spike blood sugar and suggesting behaviour changes, without requiring a CGM for ongoing use.  January AI also positions CGM as optional after an initial training period, depending on the pathway a user chooses.

Key features of January AI

• Predictive glucose insights, designed to estimate glucose response to meals and behaviours, even when you are not wearing a CGM.
• Food tools that support decision-making, including scanning or searching foods to see predicted impact.
• A CGM-supported “training” phase is commonly referenced in research and reviews, where the app learns from your data before relying more heavily on prediction.
• More self-directed by design, with recommendations generated through the model rather than ongoing practitioner support.

Plans and availability notes

January AI’s help centre states the first month costs $288 and includes an activation kit plus access to the app. Ongoing membership pricing and availability can vary, and the safest way to confirm current options is through January AI’s own checkout flow for your location.

A quick caution worth noting

Because January AI is heavily food-response focused and uses daily prompts and behaviour nudges, it may not suit everyone. Anyone with a history of disordered eating or food anxiety should approach these tools thoughtfully and consider professional support.

Vively

Vively is designed for people who want clear, practical insight into metabolic health using real-time glucose data. The program pairs a CGM sensor with the Vively app, where glucose trends sit alongside the habits that shape them most, like meals, movement, sleep, and stress.

Vively now uses the SIBIONICS GS3 CGM sensor. This matters because the sensor experience shapes how easy it feels to stay consistent. GS3 is designed to deliver frequent Bluetooth updates, support a stable in-app connection, and offer a smaller, lower-profile sensor that’s easier to wear day to day.

What you do inside the program is just as important as what you track. Vively is structured to help you understand your patterns first, then apply them through app-based guidance and habit support, so you are not left guessing what to do with the data.

Direct Comparison

Target Audience

• January AI: Often resonates most with people who want glucose insights primarily for food decisions and weight-related goals, and who like the idea of prediction without needing to wear a CGM continuously.‍
• Vively: Built for broader metabolic health goals, including weight management, PCOS, perimenopause and menopause support, energy, cravings, and lifestyle pattern-building, using CGM as a learning tool rather than a one-off experiment.

User Experience

• January AI: Sleek and app-led, with prediction features that can reduce reliance on continuous wear. Depending on the program pathway, the structure can feel more “task-based”, which some users love for accountability, and others find too rigid.
• ‍Vively: Designed for flexibility. You can keep it simple and focus on trends, or go deeper with tracking when you want more context. The emphasis is on turning readings into repeatable habits with a program structure that supports follow-through, not just insight.

Holistic Approach

• Vively: Holistic by design. Glucose is viewed alongside the key lifestyle inputs that influence it, with optional access to dietitian support so you can get a human layer of interpretation when needed.
• January AI: Strong on prediction and food-response guidance, with insights generated through its modelling and logged data.

Price

January AI’s published pricing includes a first month at $288, with an annual subscription option listed at $380.

Vively bundles the CGM sensor with interpretation and context as part of a structured program.

• 1 sensor (14-day use): $199 per device
• 2 sensors: $179 per device
• 4 sensors: $125 per device

Final thoughts

The decision between January AI and Vively depends on your personal needs and health objectives.

January AI and Vively offer distinct approaches to optimising metabolic health, catering to a range of user needs and preferences. January AI excels in predictive modelling for glucose monitoring, providing immediate feedback on dietary choices and personalised meal plans. However, its lack of human support and potential concerns regarding the development of eating disorders may deter some users.

On the other hand, Vively emphasises real-time monitoring through continuous glucose monitors (CGMs) and offers a comprehensive approach to health management, including diet, exercise, sleep, and stress, with the added benefit of optional access to 1:1 dietitian support. Ultimately, individuals should carefully consider their health objectives and preferences when choosing between these two apps.
