What is the best CGM app in 2026?

There is no single best CGM app because they serve different goals. Levels suits metabolic-wellness self-optimizers, Nutrisense suits people who want 1:1 dietitian coaching, Signos is focused on weight management, and Endobits suits people who already wear a CGM and want an affordable clinical report to share with their doctor. Choose by what you actually want: coaching, weight loss, or a doctor-facing read of your data.

Do CGM apps require a prescription?

Many consumer CGM programs now use over-the-counter sensors and do not require a prescription, though eligibility criteria apply. Some GLP-1 plans and certain sensors do require clinician involvement. Follow each provider's requirements and your clinician's guidance.

Which CGM app is cheapest?

Costs vary by model. Subscription programs that bundle sensors and coaching typically run over 100 dollars per month, while a membership-only app like Levels is lower but sells sensors separately. Endobits uses a pay-per-report model, about 7.99 dollars per report or free with data donation, using a CGM you already own, which can be the lowest-cost option if you do not need coaching.

Best CGM Apps of 2026

7 min read · Updated July 2026

"Best CGM app" is really four different questions, because these products are built for different goals. Some are coaching subscriptions, one is aimed squarely at weight loss, and one turns your glucose data into something your doctor can use. Below is an honest 2026 comparison of the four most-asked-about options — Levels, Nutrisense, Signos, and Endobits — by cost, model, and who each actually fits. Prices are as publicly listed in 2026 and change often, so confirm on each provider's site.

At a glance

App	Cost (2026)	Model & focus
Levels	~$15/mo or $80/yr; sensors extra	App membership; metabolic-wellness coaching
Nutrisense	~$149–$215/mo; sensors included	Subscription; 1:1 dietitian coaching
Signos	~$127–$225/mo; sensors included	Subscription; weight management (FDA-cleared)
Endobits	~$7.99 per report, or free with data donation	Pay-per-report; clinical read of your CGM data for your doctor

Levels — best for metabolic-wellness self-optimizers

Levels is an app-first membership (about $15/month or $80/year, sensors sold separately). It leans into AI food logging, macro tracking, and adaptive programs for weight, heart health, and glucose stability. If you are broadly healthy and enjoy experimenting with meals and habits in a gamified app, Levels is built for you. See the full Endobits vs Levels comparison.

Nutrisense — best for dietitian coaching

Nutrisense bundles two sensors a month plus 1:1 registered-dietitian coaching on plans that run roughly $149–$215/month. The human coaching is the point: someone to interpret your meals and help you adjust. If you want guidance rather than just data, this is the strongest fit. See the full Endobits vs Nutrisense comparison.

Signos — best for weight management

Signos is focused specifically on weight loss, pairing an AI app with sensors (about $127–$225/month depending on term, sensors included). In 2025 the FDA cleared its glucose-monitoring system for weight management, available over the counter regardless of weight-loss goal, and it offers a separate clinician-prescribed GLP-1 plus CGM plan. If weight is your main objective, Signos is purpose-built around it.

Endobits — best for a doctor-facing clinical read

Endobits is the odd one out here, on purpose. Instead of a coaching subscription, it analyzes the data from a CGM you already wear and produces a structured metabolic report — your patterns, variability, and risk context — that you can hand to your own clinician. You pay about $7.99 per report, or nothing if you donate your de-identified data for research, and there is no subscription. It fits people managing type 2 diabetes or prediabetes, and anyone who wants their glucose data to feed a real care conversation rather than a standalone wellness score. Endobits is decision support used under clinician oversight — not a diagnosis, and not a medical device.

How to choose

Want coaching and habit change? Nutrisense (dietitian) or Levels (app coaching).
Focused on weight loss? Signos is built around that goal.
Already have a CGM and want a low-cost, doctor-facing report? Endobits.
Watching cost? A pay-per-report model can be far cheaper than a monthly subscription if you do not need coaching.

Many people use more than one over time — a coaching app to learn their patterns, then an affordable report to bring to appointments. If you are still deciding whether continuous monitoring fits at all, choosing a CGM walks through the basics.
