Beta opens October 19 · Android
Be one of the first builders
We're opening Keystone to a small group of early testers before the public launch.
You get the app free, and a direct line to the person building it. In return, we ask for your honest feedback.
What We're Asking
• Install Keystone on an Android phone and keep it installed for 14 days. (Google requires this for every new app.)
• Use it a little each day: set up a few pillars, place a brick, see what happens.
• Tell us what's confusing, broken or missing. Just reply to the email below.
How to Join
1. Request to join the tester group
Use the Gmail address you use on your Android phone. We approve every request personally, usually within a day or two. Places are limited.
Request to Join2. Once approved, opt in to testing
You'll get an email from Google Groups when you're approved. Then open the opt-in link below on your phone and tap Become a tester. It works only for approved testers. Already on our close-circle list? Start here.
Opt In to Testing3. Install and start building
After opting in, the Play Store page shows an Install button. Open Keystone, set up your pillars (or let the AI Architect draft them), and place your first brick. Try adding the home-screen widget too.
Good to Know
Do I need an Android phone?
Yes. Keystone is Android-only for now, and the beta needs a Gmail address. On an iPhone? Email us and we'll tell you when it's available.
Is it free?
Yes, during the beta. Every tester also gets 5 free uses of the AI Architect.
What happens to my data?
Your pillars, bricks and journal stay on your phone. Nothing is collected unless you use the AI Architect or turn on Google Drive backup. Read the details in our privacy policy.
