Signos is a real glucose-tracking membership for adults 18 and older who do not use insulin. The maker says it pairs a Stelo continuous glucose monitor (CGM) with an app that helps you spot how meals, movement, sleep, and other habits line up with your glucose patterns. It can be a practical option if you want day-to-day feedback instead of guessing which routines feel sustainable for you.

Signos uses a sensor placed on your skin and an app on a compatible phone. Its plan is built around behavior feedback, not a replacement for medical care. A 2020 article in Diabetes examined whether blood-glucose patterns could predict mood and energy, while a 2023 wearable-device study in Metabolism Open examined links among glucose variability, sleep quality, and daily steps in people without diabetes. Those are the kinds of daily patterns the service is designed to make easier to see.
Is Signos legit, and what does it actually do?
Yes. Signos, Inc. offers a mobile app and subscription service that works exclusively with the Stelo biosensor. The company says the system receives data from an integrated CGM sensor, then continuously records, analyzes, and displays glucose values for people 18 or older who are not on insulin.
The practical appeal is simple: you can see a trend after a meal, workout, poor night of sleep, or change in routine instead of trying to remember how you felt days later. The maker says the app combines glucose data with logged meals, workouts, weight, and other habits to provide personalized guidance.
A CGM measures glucose through interstitial fluid, the fluid between cells, using a small flexible filament placed under the skin. It sends readings to your phone over time. That differs from a finger-stick glucometer, which gives one blood-glucose reading at the moment you test.
Is Signos CGM good for weight-management planning?
Signos may suit you if your goal is to notice patterns and make your own food and activity choices with more context. The maker frames the program around building glucose-stable habits and weight-management support. That can feel more useful than broad advice when you want to understand why one breakfast leaves you satisfied while another leads to an afternoon slump.
It is not a prescription weight-loss plan by itself. Signos says its membership does not include prescription medication or medical supplements. Its terms also say Signos is not a medical provider, although registered dietitians may be involved and certain third-party services may be provided through independent providers.
If you are also considering a medication-based program, compare the full care model before you decide. Our ReadyRx guide explains the practical pricing questions that can matter in a telehealth plan, while the Zealthy guide covers how advertised program prices can differ from total costs.
What does Signos cost?
Prices below were shown on October 14, 2026; check the checkout for today’s price. Signos says plan prices can vary with promotions and other factors. The site advertised a 25% code, AUTUMN25, at checkout when these terms were displayed.
| Plan length | Listed monthly price | What the company says is included |
|---|---|---|
| 1 month | $299/month | Stelo biosensor and Signos app membership |
| 3 months | $199/month | Stelo biosensor and Signos app membership |
| 6 months | $169/month | Stelo biosensor and Signos app membership |
Signos says it is not currently covered by insurance. It says some members may be able to use HSA or FSA funds for reimbursement. Ask your plan administrator before treating reimbursement as available to you.
The listed plans do not include a bring-your-own-sensor option or a software-only option. Signos says all of its plans include Stelo, and the app is designed to work only with that sensor.
How does Signos compare with a glucometer, Levels, or Nutrisense?
There is no single “most accurate” monitor for every person or purpose in the information here. A finger-stick meter and a CGM answer related but different questions: a meter gives a single capillary-blood result, while a CGM shows a stream of readings and direction over time.
| If you want to know | Tool to consider | Why it may fit |
|---|---|---|
| Your glucose at one specific moment | Traditional blood-glucose meter | A direct spot check with a finger stick. |
| How meals, activity, sleep, and time of day relate to trends | CGM membership such as Signos | Continuous readings and an app-based pattern view. |
| Which CGM membership to choose | Compare the sensor, app, coaching, plan length, and total cost | These services package different levels of guidance around CGM data. |
Healthline lists Signos among CGM plans aimed at personalized advice and notes that CGM costs can vary with features, insurance, and location. Its glucose-monitor guide also notes that device choice should match the features and sensor-wear period you need.
Signos publishes comparisons with Levels and Nutrisense. When you compare them, start with the questions that change your experience: Which sensor is included? Is professional nutrition support included? How long is the commitment? What does renewal cost? Can you use your own sensor? That is more useful than treating one brand as universally best.
What side effects or safety issues should you know?
The main immediate issue is the sensor site. Signos notes that some people experience skin irritation. If irritation persists, the company says to contact a healthcare provider. The company also says a compatible mobile phone is required and that the app may not work on every device, operating system, carrier, or network.
Ask a clinician first if you use insulin, have diabetes-related treatment questions, or would make a medication decision because of a CGM reading. Signos states that its system is for people not on insulin and that users should not take medical action from device output without consulting a qualified healthcare professional. A Diabetes Care study found that perceived symptoms can be part of recognizing hypoglycemia, so a reading and how you feel both deserve context from your care team.
That distinction matters. A CGM can show a pattern, but it does not tell you which medication change is right for you. If you have a glucose reading that worries you, use the care plan you already have and contact the clinician who manages it. For medication-based weight-loss care, our Willow GLP-1 guide shows the kinds of side-effect and medication questions worth bringing to that conversation.
What about GLP-1 medication through Signos?
Signos says clinical services available through its platform are provided by OpenLoop Health and other independent networks of U.S.-licensed clinicians. Those clinicians make their own eligibility and prescribing decisions, according to the company. Signos says it does not manufacture, compound, dispense, or distribute medication.
The company says medication costs may be included in a Signos program where offered. It also says compounded medications connected with the program are made in FDA-registered facilities, are not FDA-approved, and have not been evaluated by the FDA for safety, efficacy, or quality. Before enrolling in any medication pathway, ask who the prescriber is, which exact medicine may be considered, which pharmacy fills it, whether medication is included in the stated price, and how follow-up works.
What does glucose data tell you about weight loss?
Glucose data can make routine choices easier to examine, but it is not a scorecard for your worth or a one-step explanation for body weight. A clinical review indexed by PubMed describes how expected weight loss may not occur even when someone is trying to follow a plan, and it recommends active clinician participation. If past diets have felt like endless guesswork, the useful next move is often to look for repeatable habits: what you eat, when you move, how you sleep, and what you can keep doing next month.
You may see online references to the “30/30/30 rule,” a popular routine involving protein early in the day and 30 minutes of low-intensity activity. The material here does not establish a specific Signos protocol for that rule. Use your own readings as conversation material, not as instructions to create a rigid routine.
A glucose average of 140, a single high reading, or a symptom cannot be converted into a personal diagnosis on this page. Bring your CGM trend, medication list, and questions to a clinician who can put them in context. The product can help you arrive with clearer observations.
What should you know about privacy, login, shipping, and support?
Because the app handles glucose and other health-related information, take a minute to read the privacy terms before you sign up. Signos says it may collect account details, health and biometric information, questionnaire responses, billing or shipping information, device and usage information, and other data needed for its services. Its privacy policy describes how it may use that information, including for service delivery, research and development, and personalization.
Signos is available in the United States and says it ships to all 50 states, but not APO/FPO addresses. The company says your app-store setting must be set to the United States to download and use the app.
For Signos login access, protect your password and keep the email address on your account current. The terms say you should notify Signos immediately if you suspect unauthorized account access. For a subscription, shipping, or account issue, use the company’s customer-support ticket process or Knowledge Base.
Before you join Signos
- Confirm that your phone is compatible with the Signos app.
- Choose the plan length that fits how long you want to collect patterns.
- Check today’s price, promotional terms, and the current cancellation or refund terms directly with Signos before payment.
- Ask whether HSA or FSA reimbursement applies to your situation.
- Ask a clinician how CGM readings fit with your medicines and existing care plan.
- If you are considering the clinical pathway, ask who provides care, what medication options may be considered, and what the full program price includes.
Signos may be a useful fit when you want a Stelo-based CGM and an app that turns daily readings into habits you can discuss and refine. Start with the shortest practical question: do you want a one-time glucose check, or do you want several weeks of trend data to guide choices you can realistically keep?
