The short answer
Stick with built-in Screen Time if you need:
- one bedtime cutoff for the whole phone, or
- a daily time cap on a couple of apps.
Consider an app blocker like Fokus Zone if you want:
- apps blocked when you arrive somewhere, such as the office or library,
- several schedules that block different apps at different times,
- separate restriction profiles for work, study and evenings.
What iPhone’s built-in tools actually do
Downtime blocks everything except an allow list during a schedule. It can vary hours by day, but it is one rule for the whole device.
App Limits set a daily time budget per app or category. When time runs out, the app is shielded until midnight, unless you ask for more.
Focus modes (Work, Personal, Sleep and custom ones) can turn on by time, by location or when you open a certain app. They silence notifications and can hide Home Screen pages. They do not stop an app from opening.
All three are free, built in and trustworthy. The question is whether their rules match how you get distracted.
Side-by-side comparison
| Downtime | App Limits | Focus modes | Fokus Zone | |
|---|---|---|---|---|
| Blocks apps from opening | Yes | Yes, after the budget | No | Yes |
| Triggered by time | Yes | Daily reset | Yes | Yes |
| Triggered by location | No | No | Yes | Yes |
| Several rules with different apps | No, one schedule | Per app or category budgets | Several Focuses, but no blocking | Yes, multiple profiles |
| Different schedules per day | Hours per day | No | Yes | Yes |
| Block whole categories | Via allow list | Yes | Hides notifications only | Yes |
| Temporary access | Ask for more time | Ask for more time | N/A | Yes |
| Usage statistics | Screen Time reports | Screen Time reports | No | Daily usage, weekly and monthly trends |
| Cost | Free | Free | Free | Free, optional Premium |
Where built-in Screen Time is enough
- A simple bedtime. Downtime from 23:00 to 07:00, with phone and messages allowed, covers it.
- One problem app. If it is only one game eating your evenings, an App Limit of 30 minutes a day may be all you need.
- Notification overload, not app opening. If the issue is being pulled in by pings, a Focus mode fixes it without blocking anything.
- Parents with Family Sharing. Screen Time’s family controls are made for managing a child’s device from a parent’s.
Where Fokus Zone helps
- Place-based habits. “No social media at the library” is impossible with Downtime, and Focus modes only hide notifications. Fokus Zone uses geofencing to switch restrictions on as you enter an area. See how to block apps by location.
- Different rules for different parts of the day. A morning block for news, a work block for social media and games, a bedtime block for everything. Details in blocking apps on a schedule.
- Keeping work tools available. A block list (instead of Downtime’s allow list) means you choose only what to remove. That matters during the workday, covered in app blocker for work.
- Seeing progress. Statistics show your daily usage, your most time-consuming apps, and trends over weeks and months.
Same foundation, different rules
Fokus Zone does not work around iOS. It uses Apple’s public Screen Time APIs: FamilyControls for permission, ManagedSettings to apply restrictions and DeviceActivity to run schedules. Apple’s Screen Time API documentation describes how these fit together.
One consequence is good for privacy: when you choose apps to block, iOS hands the app opaque tokens, not the names of the apps you picked. On top of that, Fokus Zone keeps all data on the device, uses location only for geofencing, and collects no personal information.
An honest note on willpower
No app blocker, built in or third party, makes it impossible for you to use your own phone. Screen Time can be overridden by anyone who knows the passcode, and you can always delete an app or change its settings. What a good blocker does is add friction at the right moment, so that the automatic reach for your phone turns into a decision. Rules that switch on by themselves, because of where you are or what time it is, add that friction without you having to remember.
Fokus Zone runs on iPhone with iOS 18 or later. It is free, with an optional Premium subscription for unlimited restrictions, advanced scheduling and detailed analytics.
