You pick up your phone for "just a second" β€” and 45 minutes disappear. Cala stops that cycle with real app blocking and a ten-second breath that turns impulse into intention. When you open a blocked app, Cala holds a shield. You breathe, then choose how long you need β€” 5, 15, or 30 minutes. When time's up, the app locks itself again. You decided in advance, so the moment doesn't get a vote. WHAT CALA DOES β€’ Blocks any app or website with Apple's Screen Time shields β€” real blocking, not reminders β€’ No Shortcuts to wire up and no workarounds to maintain β€” grant Screen Time access once and you're protected β€’ Protects on your schedule: work hours, evenings, overnight, or all day β€’ A short breathing exercise before every unlock β€” a pause, not a punishment β€’ Timed access that re-locks automatically when you're done β€’ Three strictness levels β€” Standard, Strict, and Locked. As firm as you need. β€’ Habits and tasks live inside your protected hours, so the shield offers a better option, not just a wall β€’ A Focus Score that measures the time you protected and the wins you stacked β€” not your failures β€’ A weekly review of your wins, ready every Monday AS FIRM AS YOU NEED Standard asks for a calm ten-second breath before each unlock. Strict makes each unlock cost a little more. Locked holds the line completely β€” with a once-a-day emergency pass, because life happens. PRIVATE BY DESIGN Cala never sees which apps you open or for how long. Apple's Screen Time design keeps that on your device, and we like it that way. FREE TO START One schedule, unlimited blocked apps, two habits, your Focus Score, and the full breathing unlock β€” free. Cala Pro adds unlimited schedules and habits, Strict and Locked levels, and your complete history. Your phone, your rules. Cala keeps them. Terms of Use: https://heycala.com/terms
