About

I read Economics and Management at Oxford, taught myself to code this summer and built Motily alone: a daily check-in for men's fertility built around the 74 days it takes to make sperm, with semen analysis results explained against the WHO 2021 limits. Every claim carries a source. Not a doctor. Before this I ran a small jewellery business from the age of 16. London.

Motily - The daily check-in for men's fertility

Motily is a men's fertility app built around one fact: sperm take about 74 days to make, so the habits a man keeps over the next two to three months shape what a semen analysis will show. Two-minute daily check-in across eight evidence-backed habits, a score that shows where the points are, a 74-day journey, semen analysis results against the WHO 2021 reference limits, and a page for your partner. Measures nothing, diagnoses nothing, cites everything. Free during launch.
