Cala: App Blocker, Screen Time
Focus, Habit & Self Control
Only for iPhone
Free · In‑App Purchases
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 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 — 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
• Blocks any app or website with Apple's Screen Time shields — real blocking, not reminders
• No Shortcuts to wire up and no workarounds to maintain — grant Screen Time access once and you're protected
• Protects on your schedule: work hours, evenings, overnight, or all day
• A short breathing exercise before every unlock — a pause, not a punishment
• Timed access that re-locks automatically when you're done
• Three strictness levels — Standard, Strict, and Locked. As firm as you need.
• Habits and tasks live inside your protected hours, so the shield offers a better option, not just a wall
• A Focus Score that measures the time you protected and the wins you stacked — not your failures
• 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 — 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 — free. Cala Pro adds unlimited schedules and habits, Strict and Locked levels, and your complete history.
Your phone, your rules. Cala keeps them.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Cala 1.0.2 makes the numbers you watch every day trustworthy and the reminders you set respectful of what you already did.
IMPROVED
• Streaks, perfect days, and weekly totals now agree everywhere — Home, Habits, Progress, and the weekly review tell one story
• A habit you finish early no longer reminds you about it later that day
• The weekly review arrives only when there is a week worth reviewing
• Focus sessions let you know when they finish, even if Cala is in the background
• Switching a schedule between the Block List and a custom list keeps both lists
• Faster opens for long histories
FIXED
• Reminders, recaps, and streak warnings land on the right day around midnight
• Milestone celebrations are no longer lost to the notification permission prompt
• Turning on a habit reminder now tells you if notifications are off
• Dozens of smaller consistency fixes across Progress, Tasks, and onboarding
