Google makes every new app pass a test first: 12 people with Android phones keep it installed for 14 days. That's it. Be one of the 12.
This test is Android-only, but you can still get LockIn as an app right now: open lockinstudy.vercel.app in Safari, tap ••• → Share → Add to Home Screen. Know someone with an Android? Send them this page.
Your email is only used to add you to the test and is never sold or shared. Privacy
