Beta program
Join the app beta
The Bigger Blacker Book is already on the App Store and Google Play. The beta is where new features land first, so you can try them and tell us what breaks before everyone else gets them. You join straight through Apple or Google — this site never asks for your email address or any account details, and keeps no record of who joins.

Beta news and feedback
We don’t keep a mailing list. New builds, what to test, and known issues are posted on the blog, which you can also follow in any feed reader through its RSS feed.
To tell us about a problem on iPhone, open the app in TestFlight and tap Send Beta Feedback, or take a screenshot while using the app. On Android, use the private feedback option on the app’s Google Play listing. TestFlight may offer an optional email field with your feedback — leave it blank to stay anonymous.
