You open an app for “just a minute.” Then you look up, and much more time has passed. XLocker helps you create a little distance from the apps that easily pull you in, so you can give more time to the things you care about: work, study, reading, family, rest, or simply being present. Choose the apps you want to manage, then decide what works for you: • Lock selected apps when you want a clearer boundary • Hide selected apps to reduce visual distractions • Set a daily protection goal of 30 minutes, 1 hour, or no fixed goal • Follow your own pace instead of chasing perfection • Keep a record of the time you set aside and see your effort build over time You do not need to change everything at once. Start with one app. Start with half an hour. Or start without a target at all. Every time you choose to stay with what matters, you are making space for the life you want to live. From this moment, leave a little more time for yourself. XLocker is designed to help reduce app-related distractions. It does not guarantee reduced screen time, increased productivity, or any particular result. Features may vary depending on your device and Screen Time permissions.
