Bokkiman is a private self-care app for men to log their morning EHS (erection hardness), ejaculation, sleep, alcohol and mood — one tap a day. See how your lifestyle relates to your body's rhythm: a calendar heatmap, trend charts and factor correlations turn daily logs into insight about your own patterns. No login, no account. Everything stays on your device (works offline as a PWA). Free, ad-free, in 10 languages. CSV export anytime. A serious health tool — not adult content.

Hi Product Hunt! "Bokki" means "erection" in Japanese — so Bokkiman is a men's health log built around one simple daily habit: recording your morning EHS (erection hardness) with a single tap. Morning erections are a quiet, honest signal of your physical condition. By logging them alongside your sleep, alcohol and mood, you start to see your own patterns — like "I wake up in better shape after a good night's sleep" — and can notice early changes over time. A few things I cared about while building it: - Private by default — no login, no account. Everything stays on your device and works offline (PWA). - Low friction — every field is optional, so a partial log still counts. - Insight, not just data — calendar heatmap, trends, and factor correlations. - Free & ad-free, in 10 languages, with CSV export so your data is always yours. This is meant as a serious self-care tool — a way to stay aware of your body — not adult content. I'd love your feedback. Thanks for checking it out!

genuinely nice that it stays on-device with no login and works offline, feels respectful for something this personal.

@glayeg2g Thanks. Glad it comes across. Privacy was the starting point, no backend at all.
