Frequently asked questions
Can you use Signos without a CGM?
No. Signos says all of its plans include the Stelo biosensor and that it doesn't offer a bring-your-own-CGM option or a software-only subscription.
How much does Signos cost?
Signos lists its 6-month plan at $169 a month, its 3-month plan at $199 a month and its 1-month plan at $299 a month, with sensors included. It says it isn't covered by insurance, though some members may be able to use HSA or FSA funds.
Is Signos FDA-cleared?
Yes. The FDA cleared the Signos Glucose Monitoring System for over-the-counter use through a 510(k) (K250106). Helsa is an informational wellness app, not a medical device.
How does Helsa help with weight loss without glucose data?
Helsa tracks diet, activity, sleep, stress and body composition, analyzes lab markers like A1C and triglycerides, and its AI coach suggests small daily changes. It can't show your real-time glucose curve; if you want that, a CGM program like Signos is the better fit.
Is a CGM more accurate than an app without one?
Yes. A CGM measures your glucose directly, so it will always be more precise than insights based on meal logs and lab results. The trade-off is ongoing sensor cost and wear: Signos notes that about 20% of Stelo sensors may not last the full 15 days.
