How to block apps on iPhone until you finish a task
Published · 6 min read
Option 1: Screen Time App Limits
App Limits are built into iOS. Go to Settings › Screen Time › App Limits › Add Limit, pick the apps or a whole category such as Social, and set a daily amount of time.
When the time runs out, the app shows a “Time Limit” screen. You can still tap “Ignore Limit” and get one more minute, 15 minutes or the rest of the day, unless you set a Screen Time passcode that someone else keeps.
- Good for: capping total daily use of an app.
- Not built for: “first the task, then the app”. The limit counts minutes, not what you did.
Option 2: Downtime
Downtime (Settings › Screen Time › Downtime) blocks every app except the ones you allow, during a schedule you choose, for example 21:00 to 7:00.
It works well for evenings and sleep. It is less useful in the middle of the day, because it blocks everything at once and ends at a fixed time, whether or not you did what you planned.
Option 3: lock apps until the task is done
Since iOS 15 and 16, Apple lets apps use the Screen Time API (FamilyControls, ManagedSettings and DeviceActivity) to shield apps you choose. That makes a different rule possible: the apps wait until you complete a task.
Do It First uses this. You create a mission, for example “Read for 15 minutes at 8:00”, and choose which apps wait. At mission time those apps show a shield. When you finish and log it with a photo, the mission is confirmed and the apps open again.
- Your choice of apps stays private: Apple’s picker gives the app tokens, not your activity inside other apps.
- You can pause when you really need to; a break is part of the design.
- Each confirmed mission earns XP and keeps a streak, with a pixel companion that grows with you.
Which one should you use?
Use App Limits if your goal is “less of this app per day”. Use Downtime for a phone-free evening. Use a task-based lock when the goal is to do one real thing first: read, study, exercise or finish work before the feed.
They also combine well. Many people keep Downtime at night and use mission-based locks during the day.
Questions
Can I block apps on iPhone without an extra app?
Yes. Screen Time App Limits and Downtime are built into iOS. They block by time, not by task, and you can ignore the limit unless someone else holds the Screen Time passcode.
Can an app see what I do in Instagram or TikTok if I block them?
No. With Apple’s Screen Time API, the blocking app receives anonymous tokens for the apps you pick. It cannot read your messages, feed or activity inside those apps.
What iPhone do I need for Do It First?
An iPhone with iOS 17 or later. Blocking uses Apple’s Screen Time permission, which you grant once.
