By far, the most advanced and complete testosterone calculator available on Android.

This app is designed to assist clinicians and individuals in accurately determining circulating free and bioactive testosterone levels.

This app comes with unique features like:
- immunoassay corrections (adapted to the technology used in the lab)
- full state-of-the-art implementation of Vermeulen's and Mazer's formulas (and many other well-known formulas available)

This app also considers the ratio between the luteinizing hormone and total testosterone to display eugonadal situations, compensated hypogonadism, primary hypogonadism, or secondary hypogonadism.

This application reduces the risk of errors when performing complicated calculations by hand. To use the app, input current lab values into the specified boxes for:
- Total testosterone
- Estradiol (E2) (optional)
- Estrone (E1) (optional)
- Dihydrotestosterone (DHT) (optional)
- Cortisol (C) (optional)
- Albumin
- Sex Hormone Binding Globulin (SHBG)
- Transcortin (CBG) (optional)
- Luteinizing hormone (LH) (optional)
