Cloister: App & Site Blocker

Cloister locks the apps and websites that pull you away, and holds the line until you're done.

Pick what distracts you: social media, videos, games or any other app, whole app categories, and websites. Choose when: on a schedule that starts on its own, such as weekdays from 9 to 5, or only when you tap Start.

TAILOR YOUR LEVEL OF COMMITMENT
Choose how each block may end:

• Flexible: end it with one tap.
• Cooldown: end early after a 5-minute wait, long enough for the urge to pass.
• Strict: no exit inside Cloister. The block runs to its end.

STAY IN CONTROL, SEAMLESSLY
Need more time? Add 15 minutes, 30 minutes or an hour to a running block in Cloister, or 15 minutes from the Lock Screen or the widget. Added time can't be taken back, so a block only ever gets longer.

Put Cloister on your Home Screen: its widget starts a block with one tap, and while the block runs it counts down the time left. Smaller widgets fit the Lock Screen.

Start a block with Siri: say "Start a block in Cloister" and pick one, or ask "What's on in Cloister?" to hear when it ends. In the Shortcuts app, Start a block runs in your own shortcuts and automations, such as when you turn on a Focus. Spotlight finds your blocks by name. Siri and Shortcuts can start a block, never end one.

Any block can also stop apps from being deleted while it runs. When you open a blocked app, Cloister's shield covers it. A running block shows on the Lock Screen and in the Dynamic Island, and you can start one from Control Center, the Lock Screen or the Action Button. If you allow notifications, Cloister tells you a minute before a schedule starts and when a block ends.

PRIVATE BY DESIGN
Cloister uses Apple's Screen Time API. The apps you pick reach Cloister only as tokens it cannot turn into names, and your rules, lists and history stay on your device. There is no account and no tracking. After its first check, blocking works offline.

Cloister runs on iPhone, iPad and iPhone Duo, open or closed.

CLOISTER PRO
Making lists and rules is free. Running blocks needs Cloister Pro: a monthly or yearly subscription, where the yearly plan starts with a 2-week free trial if you are eligible, or a one-time Lifetime purchase. Payment is charged to your Apple Account when you confirm. Subscriptions renew automatically unless you turn off renewal at least 24 hours before the end of the current period. You can manage or cancel them in your Apple Account settings.
