iPhone

Real app blocking with a breathing reset before every unlock. Build habits, track your streak, take back your time. You pick up your phone for "just a second" — and 45 minutes disappear. Cala stops that cycle with real app blocking and a breathing exercise that turns impulse into intention. When you try to open a blocked app, Cala places a shield. Before you can access it, you breathe. Not as punishment — as a reset. Then you choose how long: 5, 15, or 30 minutes. When time's up, the app re-locks automatically. That's the difference. Cala doesn't just track your screen time. It changes the moment you reach for your phone. WHAT CALA DOES - Blocks any app or website using Apple's Screen Time shields - Requires a breathing exercise before every unlock - Timeboxes your access — apps re-lock when time expires - Offers habits and tasks as alternatives at the unlock gate — do something meaningful instead - Three strictness levels: Standard, Strict, and Locked - Tracks your Protection Streak and Focus Score - Weekly Review shows your progress over time THREE LEVELS OF PROTECTION Standard: 10-second breathing unlock. Full schedule control. Free. Strict: Escalating breathing (10→20→30s). Shorter access windows. Pro. Locked: No unlocks, no breaks. Emergency access once per day. Pro. YOUR FOCUS SESSIONS Start a timed deep work session. All blocked apps stay blocked until you're done. No distractions, no negotiation. BUILT FOR PRIVACY Cala never sees which apps you open or for how long — Apple's privacy tokens make that impossible, and we're explicit about it. No accounts. No cloud uploads. Your data stays on your device. Cala Pro unlocks unlimited schedules, Strict and Locked modes, unlimited habits, and full activity history.
