Hi there!

Let’s get started using 3rd Brain

Step 1

Download TestFlight

TestFlight is an app made by Apple to allow developers like us to test apps with friendly early adopters like yourself without the hassle of publishing our app on the App Store.

Step 2

Install 3rd Brain

Once you have the TestFlight app, click on the link you got in your invite email to accept your invitation and download the 3rd Brain app.

Step 3

Register for an account

If you are the first user in your household to register for 3rd Brain, create a new account, and leave the Invite Code section blank.

If your partner is already a 3rd Brain user, and they sent you an invite code, go to Step 4

Step 4 Skip if you did Step 3

Register for an account

If your partner shared a 4-digit invite code with you, add it when you’re registering for your account.

P.S. if you missed this step, don’t worry! You can link your account with your partner’s later.

Step 5

Check out all that Bo can do for you

Explore the benefits of using 3rd Brain like reducing mental load, keeping track of what you and your partner need to do, and outsourcing all your brilliant ideas to a brain that never forgets.

Tell Bo your preferred pronouns (you can select multiple), and your birthday—they will help remind your partner to get you something off your wishlist. 😉

Step 6

Your first Brain Dump

Simply tell Bo what’s on your mind, such as things you need to get done, random thoughts you have, events coming up, or whatever comes to mind.

Bo will sift through them and create tasks and thoughts to organize them for you and your partner.

Step 7

Link up!

Once your partner joins your shared household, Bo will notify you and celebrate you both. Bo will also start showing you what your partner has been doing and thinking about. If you’d like some things to not show up in your partner’s view, set them to Private.
