The honest verdict
For most non-diabetic adults trying CGM for the first time, the differences are smaller than the marketing implies — sensor accuracy is similar across the consumer brands. Pick on price (Stelo by Dexcom: $89/mo vs Ultrahuman: $129/mo) and app preference. Read both in the dedicated 2026 CGM guide.
Why both might fail you (and what to do instead)
CGM data without a behaviour-change framework produces graphs without action. The honest question: will you actually change your meals based on what you learn, or just spend $90/month watching squiggles? If you don't have a clear hypothesis to test, defer the purchase until you do.
