LockedIn automatically tracks what websites and apps you use throughout your day and can suggest time limits.
The Block Agent learns how you actually spend your time and suggests the right blocks. It can also set up or tweak blocks from a single sentence.
Most blocks stay flexible. But when you really need to lock in, switch on Strict Mode before a session. While it's on, you can't quit or force-quit LockedIn to bypass your blocks. Turning it back off takes up to an hour, or until your block ends.
Download the app and you're done. No Chrome extensions, no fiddly permissions, no weird setup.
