Free, private, and built on real data. Everything runs on your device — nothing is sent anywhere.

Penis Size Percentile Checker See where your size sits against real medical data. Private, on-device, and almost certainly reassuring. Lasting-Time Checker Worried you finish too fast? See how long you last against the real average (~5 minutes, not what porn shows). STI Test Timing Checker Had a risky exposure? See when each STI test becomes reliable, and the 72-hour windows that matter right now. Semen Analysis Checker Translate a confusing semen report against the WHO 2021 reference values, in plain English. Not a diagnosis.
