About this app

The Bigger Blacker Book is a sexual health app intended for use by men that sleep with men (MSM). It was designed to make it easy to keep track of whom you have sex with (whether you know their name or not), the activities you did, and the level of risk you incurred. The app also keeps track of your STI screenings, so that you know what you were tested for, what the results were, and whom you need to contact in the event something comes up positive. It will also remind you when you should go get tested again and when to take preventative treatments.

Stop using spreadsheets and notepads to keep track! Let this app keep track for you, and show you lots of analysis on the activities and numbers you are most interested in!

This app was written by The Better Fraternization Foundation which strongly believes in privacy and data security, and that sex should be fun and had responsibly. Let us help you and together we'll make a stronger, healthier community.

Ratings and reviews

Overall I like the app but importing contacts doesn't work. It just hangs importing 1 person. Also, setting stats manually has to be done twice to save and you can't remove the date you met.

I get tested for STIs regularly (take notes people! ;) ) and this app is super helpful with a lot of the questions asked at my appointments. Very customizable and user-friendly. Also, "I hear" the app developer is quite the hottie! ;)

I really like the concept for this app, but it doesn't allow you to backup your database to anywhere other than Dropbox, which I don't use. Plus, it seems like if I don't use it for a month or so, when I open it again, all my data is gone, making it less than useful...
