ZeroPercent : No-Tantrum Timer

Managing screen time with children often ends in frustration, negotiation, and tantrums. ZeroPercent is a parental control tool designed to completely eliminate this daily friction. Instead of fighting with your child to hand back the device, simply set the ZeroPercent background timer and let the app do the heavy lifting. Who is this for? ZeroPercent is built specifically for parents, caregivers, and guardians of toddlers and young children who struggle with screen time transitions. How does it work? When the hidden countdown reaches zero, ZeroPercent seamlessly takes over the screen, creating the illusion that the device has run out of power. To the child, the battery has simply died—removing the parent from the role of the "bad guy." No more arguing, no more pleading, and no more meltdowns. Once your child hands the device back, a discreet, parent-only unlock sequence (such as tapping specific corners of the screen) instantly restores normal access. Core Features: Effortless Setup: Enter the desired minutes, start the timer, and hand the device over. Background Operation: Runs quietly in the background without interrupting their favorite apps, games, or videos. The "Dead Battery" Defense: Shifts the blame of ending screen time directly to the device. Secret Parent Unlock: Regain access instantly using discreet tap gestures (like the 4-Corner Tap) that children cannot easily guess or replicate. Absolute Privacy: Operates 100% locally on your device. ZeroPercent does not require an account, does not track analytics, and collects zero personal data. ZeroPercent Premium (One-Time Upgrade): While the core 15-minute timer is completely free, parents can unlock our Premium features for a single, one-time fee. Extended Timers: Set custom countdowns longer than 15 minutes for longer trips or specific viewing limits. Stealth Mode: Completely hide the active timer notification and status bar icons, ensuring tech-savvy kids cannot see the countdown running. Restore peace to your daily routine and end screen time seamlessly with ZeroPercent.
