Know Your Phone

Know Your Phone is a simple Android phone manager for your own device. See which apps you installed, how long you use them, which ones you never open, and which permissions they have — then lock apps you want to keep private. Screen time tracker Check today’s screen time and this week’s usage. See which apps you used most, unused apps for 30 days, and a day-by-day breakdown so you can cut doomscrolling and set a healthier phone habit. Get a daily reminder and an alert when you pass your screen-time limit. App lock PIN-lock WhatsApp, gallery, settings, or any app you choose. Unlock with your PIN (and fingerprint where your phone supports it). App lock uses Android Accessibility only for the apps you lock. Installed apps and updates Browse every app you installed. See version, last update, data use, and open Play Store to check for updates or uninstall apps you no longer need. Permission and privacy check See which apps currently have camera, microphone, location, contacts, SMS, or phone access so you can review them in system settings.
