Energy Resistance Check

A free, private read on your insulin resistance — the metabolic root of type 2 diabetes, which affects hundreds of millions of people. Your numbers never leave your device.

Energy resistance, in plain terms

Insulin resistance is your body pushing back when more energy is put into the system than it can cleanly store or burn. Push too much in, too often, and the pushback rises. These markers estimate how strong that pushback looks right now — a nudge to act, not a diagnosis.

Your numbers

Enter what you have — the more you add, the fuller the picture. Fasting values from recent bloodwork are best. Nothing is saved; this runs entirely on your device.

Fasting glucose (mg/dL)Triglycerides (mg/dL)HDL cholesterol (mg/dL)Height (in)Weight (lb)Waist (in (optional))Fasting insulin (µU/mL (optional))

Enter at least a couple of numbers above to see your signal. Triglycerides + HDL alone already give you a first read.

This is an educational screening estimate using validated surrogate markers — not a diagnosis and not a substitute for medical testing or advice. Only a clinician can diagnose insulin resistance, prediabetes, or diabetes. If your signal is elevated, or you have symptoms, please review your results with a licensed clinician.
