This keyboard has been faithfully designed to reflect the principles of creation recorded in the Hunminjeongeum Haeryebon, printed in 1446. For consonants, the guttural, lingual, labial, and dental sounds are positioned around the four cardinal directions, with the glottal sound occupying the center. The basic characters of the Five Elements (ㄱ, ㄴ, ㅁ, ㅅ, ㅇ) are arranged accordingly. For vowels, the basic characters for North (1), South (2), East (3), and West (4) (ㅗ, ㅜ, ㅏ, ㅓ) are placed around the four cardinal directions, and the first character of Heaven, Earth, and Man, 'Heaven' (・), is located in the center (5). The basic consonant keys are designed so that pushing them inward inputs jeoncheong (ㄹ, ㄷ, ㅂ, ㅈ), and pushing them outward inputs chacheong (ㅋ, ㅌ, ㅍ, ㅊ). (However, the semi-vowel ㄹ is arranged exceptionally.) The basic vowel keys are designed so that pushing them inward inputs ㅠ(6), ㅛ(7), ㅕ(8), and ㅑ(9), which have ㅣ (representing 'man') added in front, and pushing them outward inputs ㅚ, ㅟ, ㅐ, and ㅔ, which have ㅣ (representing 'man') added at the end. Pushing the central glottal sound key upward inputs the chacheong character ㅎ. Pushing the central 'Heaven' (・) key to the right inputs ー(10), and pushing it downward inputs ㅣ (representing 'man' or 'person'; no number assigned).

Ever gone to bed intending to sleep, only to realize it's 2 a.m. and you're still scrolling? Don't Scroll helps you stop doomscrolling before bed—without relying on willpower alone. Choose the apps that keep you awake. Set a lock schedule, and they'll be blocked automatically when it's time to wind down. Unlike a typical app blocker, Don't Scroll doesn't stop at "no." When you try to open a blocked app, you can take a three-minute pause with calming sounds. Sometimes that small interruption is enough to break the scroll and put the phone down. WHEN WILLPOWER ISN'T ENOUGH Every app blocker has the same weak point: you can turn it off. Late at night, that can be all too easy. Power Lock closes that loophole. Give the unlock code to someone you trust—a partner, friend, or family member. They receive it by email, and from then on, they hold the key—not you. If you force an override, they'll be notified. Scroll less. Sleep more. HOW IT WORKS • Choose the apps that keep you awake • Set your lock schedule • When you reach for a blocked app, take a three-minute pause or call it a night FEATURES • Automatic bedtime app blocking • Calming sleep sounds • Purpose-based locks for delivery apps, work distractions, and more • Nightly reports, patterns, and streaks DON'T SCROLL PLUS • Power Lock—let someone you trust hold the unlock code • Nightly pattern insights—see when you're most likely to reach for blocked apps • Premium sleep sounds—waves, airplane cabin, and pink noise • Streak protection for the occasional off night • Multiple lock schedules and unlimited app selection • PIN-protected settings • Ad-free experience Your selected apps, usage data, and sleep history stay on your device. We can't see which apps you choose. If you enable Power Lock, the email address of the person you choose is sent to our server only to deliver the unlock code and the alerts you enable.
