Bigger Blacker Book is a private sexual health and encounter tracking app built for real life — not shame, guesswork, or awkward memory gaps.
It helps you record sexual encounters clearly and flexibly, capturing the details that matter to you without forcing labels or assumptions. Your history stays organized, searchable, and entirely under your control, so you can make more informed decisions without relying on memory alone.
Beyond encounters, Bigger Blacker Book helps you manage your sexual health over time. You can track STI screenings, medications, and reminders, keeping everything in one secure place. Optional features let you share status information when you choose, while keeping your data private by default.
Originally built to serve queer communities and informed by lived experience, Bigger Blacker Book is designed for anyone who values honesty, autonomy, and better tools for managing their sexual health — without judgment, gamification, or pressure.

This app is fantastic except when iOS has any significant updates and then it seems to go buggy and not function at all. I would definitely pay for it to be kept up to date. There’s a legit need to track hookups if you’re into that (and I am), but it’s not helpful when it won’t open or crashes when trying to open or access hookup history.

This app is exactly what I want. New features are added and feedback is taken very seriously. Bugs get fixed (unlike Grindr). I wouldn’t go with any other.

Ah yes, another day that ends in “Y” and this app just…doesn’t work. Remove it and the re-add all the info back…and then two days later it just random breaks and you have to delete it and start over.
