A reverse calculator, an oil-based mL calculator for testosterone, and a nasal spray calculator are built in.

Dose titration lets you plan step-ups in advance, for example 2.5 mg for 4 weeks, then 5 mg, then 10 mg, and Regimen moves every dose to the right day. APPLE HEALTH INTEGRATION Connect Apple Health and automatically sync weight, body fat, sleep, resting heart rate, blood pressure, and oxygen saturation.
