What gets measured, gets managed.
Built for Real Life
Private Encounter & Partner Tracking
Remembering who you've been with shouldn't be stressful — or embarrassing. The Bigger Blacker Book lets you privately log encounters in a way that feels natural and judgment-free. Whether you remember names, nicknames, or just vibes, the app helps you keep a personal record that's there when you need it — and invisible when you don't.
STI Testing & Sexual Health History
Knowing your history makes it easier to take care of your future. Track STI testing dates, results, and patterns over time — all in one place. Whether you're preparing for a doctor's visit, starting a conversation with a partner, or just checking in with yourself, your health history is always accessible and easy to understand.
Medication & Prevention Support
Modern sexual health comes with powerful tools — but only if we remember to use them. The Bigger Blacker Book helps you track medications like PrEP, PEP, or treatment protocols in a way that fits into real life. Set reminders, stay consistent, and build habits that support your health without turning your life into a checklist.
Status Sharing On Your Terms
Sharing sexual health information should always be a choice. The Bigger Blacker Book lets you share relevant health details when — and only when — you decide to. There are no defaults, no pressure, and no expectations. Just tools that support honest conversations built on consent and respect.
Built for trust, designed for privacy
Your data is encrypted, your friends list is private, and all the data is stored on your Dropbox, iCloud, Google Drive, or OneDrive accounts. We never see or monetize your specific data. We do collect anonymous, non-identifying, aggregate data about your sex life for public health departments, but only if you opt in.
