ADHD? DISTRACTIONS? JUST LAZY? It doesn't matter. Stop making excuses. You know the drill: You sit down to study, and 5 minutes later, you’re scrolling social media. Your willpower is weak. You need consequences. Hush or Blush is the high-stakes focus timer that doesn't ask you nicely. It forces you to LOCK IN. KILL YOUR PROCRASTINATION This is the ultimate tool for students, ADHD brains, and anyone who needs a kick in the pants to get work done. • LOCK IN: Set your time. • ACTIVATE: Hit the button. Your phone is now a "Live Grenade." • DON'T MOVE: Lock the screen and back off. Don't try anything else or... BOOM! Public shame. • SURVIVE: Complete the session to save your dignity. DO YOU DARE TO USE THIS IN A LIBRARY? If you try to leave the app, unlock your phone, or try to cheat during a session, the app instantly punishes you with a loud, embarrassing sound of your choice. The Challenge: Can you sit in a quiet room for 45 minutes without triggering the alarm and having everyone stare at you? FEATURES - The "Shame" Engine Once a study session starts, your phone is a minefield. Don't even think about picking it up until the session ends, or you will be punished with an embarrassment of your choice—Sirens, Screams, and more. - The Mystery Crate (Rewards) You want dopamine? Earn it. Watch ads to open Mystery Crates. Unlock unique alarms or find rare "Silence Passes" to save yourself in an emergency. - Emergency Exit Strategy Real life happens. Store Silence Passes (Max 5) to exit a session silently without triggering the alarm. Hoard them—you will need them. - Call Immunity Protocol The app is tough, but fair. If you receive an incoming phone call, the system pauses automatically. No accidental shaming for answering a real emergency. WHO IS THIS FOR? • Chronic Procrastinators: If you can't put the phone down, we'll make you afraid to pick it up. • Library Warriors: Use the fear of social embarrassment to fuel your focus. • Deep Work: Eliminate the subconscious urge to "just check one notification." QUIT SLACKING. START FOCUSING. Download Hush or Blush now. Silence or Siren. Your call.
