CalmScreen: Screen Time Filter

Your kid won't put the phone down? Don't block it. Make it boring.

CalmScreen is a screen time app for kids and families that works differently. Blockers and timers end in arguments — and tech-savvy kids bypass them anyway. CalmScreen takes another path: it slowly drains the color out of the screen until scrolling simply stops feeling fun.

No cliff-edge cutoffs. No tantrums. No cat-and-mouse with uninstalled parental controls. Just a phone that gets quieter when it's supposed to.

THE GRADUAL FADE — WHY IT WORKS

Bright, saturated colors are what make endless feeds so hard to put down. CalmScreen places a gentle color filter over the entire screen — including YouTube, TikTok, and games — and fades it in slowly over minutes. By the time the screen is gray, the urge to scroll is gone. Kids put the phone down on their own, which means no resistance and no fights. A soft 10-second vibration at the end of the fade is the only reminder they need.

"CAN'T MY KID JUST TURN IT OFF?"

That's the difference between CalmScreen and built-in grayscale:

🔒 Parent PIN — settings, schedules, and the filter itself are locked behind a 4-digit PIN that stays on top of Settings, widgets, and the notification bar
🚫 Screenshot blocking during PIN entry, so the code can't be captured
🔑 Offline recovery with a 4-word phrase if you ever forget the PIN
📱 No root required — works on any Android 8.0+ phone

APP CURFEW — FILTER ONLY THE PROBLEM APPS

Choose the apps that cause the most friction (social media, video, games). CalmScreen applies the filter automatically the moment they open — the rest of the phone stays normal. Homework apps stay colorful; the doomscroll goes gray.

• Grace period for quick legitimate use before the fade begins
• Smart reset buffer so app-switching doesn't restart the timer

SCHEDULES THAT RUN THE HOUSE FOR YOU

Set up to 4 automatic schedules — bedtime, school hours, homework, family dinner. Each can have its own filter and its own fade speed. Evenings can fade to warm amber for better sleep; study time can switch to a calm, focused tone.

FILTER MODES

🌙 Dim — darker than system limits, for night reading
🌅 Sunset — warm amber, removes blue light before bed
📖 Paperback — sepia that keeps reading comfortable and makes video unappealing
🌿 Moss — calm earth tone for focused study
⚪ Focus — clean grayscale that strips the visual rewards
🎨 Custom — your own color and intensity

NOT JUST FOR KIDS

Trying to break your own doomscrolling habit? Use the gradual fade on yourself. Many adults run Paperback during work hours and Sunset after 10pm — same brain, same trick, no willpower required.

PRIVACY — ACTUALLY ZERO DATA

CalmScreen collects nothing. No accounts, no analytics, no trackers — the app doesn't even request internet permission. Everything stays on your device. Built by a solo developer who thinks screen-time apps shouldn't spy on families.

FAIR PRICING — NO SUBSCRIPTION, EVER

The filters, schedules, and gradual fade are free. A single one-time purchase unlocks the Parent PIN and full app-curfew capacity — permanently. No ads. No monthly fees. No upsells.

Works on Android 8.0+ • Available in English, Español, العربية, हिन्दी, 简体中文, தமிழ், සිංහල, اردو
