Make every open count.
once helps you take control of the apps and websites competing for your attention. Set how many times you can open them each day and how long you can spend each time.
SET DAILY LIMITS
Choose apps or websites and set a daily open limit. Share a limit across multiple apps, or give each app its own.
KEEP EACH VISIT SHORT
Set a time limit for each session. When you’re ready to use a blocked app, tap Open to start your session.
MAKE LIMITS FIT YOUR WEEK
Set different limits for different days. Schedule blocks around work, study, sleep, or time away from your phone.
MAKE YOUR LIMITS STICK
Turn on Unblockable Mode for 15 minutes to 24 hours. Once activated, selected limits can’t be opened, changed, or removed in once until the timer ends.
ALLOW A LITTLE FLEXIBILITY
Choose how many extra opens you can add each day. Extra opens expire at midnight, and your regular limits reset the next day.
PRIVATE BY DESIGN
No accounts, ads, or analytics. Your limits, schedules, and activity stay on your iPhone. Internet access is only used to retrieve icons for websites you add.
