All outputs are educational estimates, not medical advice. Life expectancy figures use population averages and simplified weight adjustments. Fat reserve math assumes excess mass is mostly adipose tissue and uses a sedentary energy estimate. Consult a healthcare provider for personal guidance.
Ideal ranges — urine pH, saliva pH & body temperature
Target wellness values for DIY tracking. Individual goals depend on health status, medications, and measurement method.
Urine pH
First-morning or random samples vary with diet, hydration, and kidney function. Track trends rather than single readings.
Saliva pH
Saliva pH shifts with meals, oral health, breathing, and hydration. Resting samples taken away from food are most comparable.
Body temperature
Ideal varies by measurement site (oral, axillary, rectal), time of day, cycle, and activity. Patterns over time matter more than a single reading.
