Stop doomscrolling and take back your time with a cute focus cat. Brainrot Blocker helps you understand and reduce the time you spend in distracting apps. Choose the apps that interrupt your day, set a daily screen time limit, and let your cat show when scrolling starts taking over. When the daily limit is reached, selected apps are blocked, helping you step away from endless feeds and return to what matters.

MEET YOUR FOCUS CAT Your cat reacts to your scrolling habits and changes its mood throughout the day: • Calm while you stay within your limit • Restless when you are close to reaching it • Overstimulated when the limit is reached • Recovering while a focus session is active TRACK TODAY’S PROGRESS See your daily screen time, completed focus minutes, and temporary app opens in one clear view.
