Take Control of Your Screen Time Ever opened an app for 5 minutes... and then realized 30 minutes were gone? Ever tried to study, work, or sleep, but your just opened the same distracting app again? Or maybe there are private apps you do not want others to open easily. Lockit helps you pause before opening an app. It does not try to stop you from using your phone forever. It simply adds one small step before access. First, protect the apps you want to manage. Then, when you want to open one, Lockit can ask you to finish a small task first. It could be a math question. It could be a simple checklist you create yourself: Drink water. Review 5 words. Clean your desk. Finish today’s first task. After the task is done, you get temporary access. When time is up, the app is locked again. This helps you ask: Do I really want to open this right now? Can I do one better thing first? Lockit is useful when: You want to focus while studying. You want fewer phone breaks while working. You want to use your phone less before bed. You want to hide and protect private apps. Your child wants to play on the phone, and you want them to answer questions before unlocking apps. This way, learning and entertainment can stay in balance. Less impulse. More focus. One small pause before the next app. Privacy is simple too: Lockit does not read content from your managed apps. Your settings, tasks, and progress stay on your device. Passwords are stored securely using Apple’s Keychain. Biometric authentication is handled by iOS.
