About

i spent 4 months reading what men actually say about their sexual health across 14 subreddits before writing a single line of code. then i built owain, a native iOS app that tracks morning erections, libido, sleep, stress, alcohol, and surfaces the patterns you can't see without data. no pills, no hardware, no diagnosis. first app, first launch.

I'm Antoine, 20, solo founder. Just launched my first app today.

hey PH, i'm antoine. 20 years old, based in paris.

i just launched owain, a daily sexual health tracker for men. the idea came from reading 1.18M reddit posts about men's sexual health and realizing nobody was building tools for this specific problem. telemedicine companies sell pills, wearables track general biometrics, but nothing sits in the middle and says "here's what your own data says about your patterns."

Launching today: Owain, daily sexual health tracking for men

hey everyone, launching owain today. it's a native iOS app that tracks what actually affects your sexual health through a 90-second daily check-in.

you log morning erection quality, libido, energy, sleep, stress, alcohol, training. the app computes a Sexual Health Index from three sub-scores (Function, Recovery, Load) and generates weekly AI observations that cite your actual data points.

Owain - Track your sexual health. Spot patterns before they worsen.

Owain is a daily 90-second check-in that tracks what actually affects your sexual health: sleep, stress, alcohol, training, morning signals. No pills, no hardware, no bro-science. The app surfaces correlations from your own data, generates weekly observations, and includes an AI coach grounded in your personal patterns. Built for men 25-45 who want to understand their body before problems start. Software-only. iPhone. Your data never leaves your hands.
