Tap in your wellbeing, symptoms, and what you took — treatments, habits, and your “O” days. Under a minute.

A clear recovery curve from a minute of logging a day.

Your result next to the anonymous community pattern.

Built by one person, for a condition that’s under-researched and too often overlooked. If it helps you, a small donation keeps the servers running and new features coming.
♥ Support the project Optional, and separate from the app. Thank you.Post-orgasmic illness syndrome (POIS) is a rare condition in which people experience symptoms — fatigue, brain fog, flu-like feelings, muscle aches, mood changes — in the hours or days after orgasm. It’s poorly understood and often dismissed, which is why careful personal tracking helps.
No. It’s a personal tracking tool, not a medical device. It doesn’t diagnose or treat, shows a medical disclaimer, and encourages you to consult a healthcare professional.
Yes. Your raw logs stay on your device. Only anonymous summary statistics can ever leave, and only if you opt in — never your notes, dates or identity. You can withdraw and delete at any time.
If you opt in, the app shares privacy-preserving summaries of what helped you. They’re pooled across everyone, and a result only appears once at least three people have contributed it.
POIS Tracker is a subscription app. It’s free to download and the annual plan starts with a free trial, so you can try everything before paying — but there’s no free tier beyond the trial: full access needs a monthly or annual subscription. Donations are separate and entirely optional.
Not yet — POIS Tracker is on iPhone first, and an Android version is coming.
