Keep the Messenger, Block the Feeds — Sorting Apps One by One
You want less screen time but you can't block the app your family and your boss reach you on. Here is the three-box sort that keeps your messenger open while the feeds go quiet, and the ten-minute checklist to do it.
You want your screen time down. You also cannot block the app your family, your kids’ school and your manager use to reach you. Search for a fix and you land on setup tutorials or blocker comparisons — but the place people actually get stuck is one step earlier: deciding which apps stay and which ones go. That sort is what this article is about. For the taps themselves, see how to set app time limits on iPhone.
The app you can’t block is usually the longest one
In Japan, MMD Institute’s 2024 tracking survey on smartphone dependence (10,000 people aged 18–69 who own a smartphone on a mobile contract, fielded 13–15 July 2024) asked the 6,251 respondents who said they overuse their phone which app or service they overuse.
| What they named | Share |
|---|---|
| LINE (the dominant messenger there) | 47.3% |
| Web browsing | 40.1% |
| Social media | 39.0% |
Broken out by age and gender, video was the top answer for men in their teens (62.2%), while social media topped the list for women in their teens (84.8%) and their twenties (67.1%).
Read the first row again. The single biggest time sink was the one app that cannot be switched off, because it is also how everyone reaches you. The names differ by country — WhatsApp, iMessage, Messenger, KakaoTalk, Slack, LINE — but the bind is identical.
So here is the conclusion up front: leave your messenger on the keep side and carry on. You can still cut hours.
Picking a whole category sweeps your messenger in with it
Screen Time’s App Limits can be set on a whole category or on individual apps. The category is faster to tap — and it is also how the app you needed ends up blocked, because messaging and social apps frequently sit in the same store category. Before you accept a category, tap into it and look at the list of apps inside.
Most people who complain that “the blocker took out my messages” never targeted the messenger at all. It was collateral from a category-wide limit. Naming apps individually removes almost all of this problem.
Sort your apps into three boxes
With only “keep” and “block” available, your messenger has nowhere to live. Add a third box.
| Box | What goes in | What you do |
|---|---|---|
| ① Always available | Phone, messaging (your main messenger included), maps, payments and transit, alarm clock | Leave alone. Put them in Always Allowed |
| ② Kept, but quieted | The parts of your messenger you browse, work chat | Don’t touch at the OS level. Change the app’s own notifications and where it sits |
| ③ Blocked by name | X, Instagram, TikTok, YouTube, news, social games | Select the individual apps and set a limit or a schedule |
Box ② is the one people skip, and skipping it is exactly why the messenger question feels unanswerable.
The ten-minute checklist
- Write down your three longest apps from last week (Screen Time’s report has them)
- Circle the ones where other people contact you → box ①
- Add every circled app to Always Allowed
- Of what’s left, the ones you open for no particular reason → box ③
- Cap box ③ at three apps. The fourth one waits until next week
- Turn off every notification from box ① apps that isn’t a real message → box ②
The order matters. Fill box ① before you configure box ③. Do it the other way round and, by that evening, some inconvenience you didn’t plan for will have you switching the whole thing off. Always pick box ③ apps individually rather than by category, and choose either a daily limit or a time window — not both at once, or you won’t know which one did the work.
No OS can block part of an app
You cannot stop one feature inside an app while leaving the rest open. “Let the chats through but close the other tabs” is not something any blocker on the market can do today, because the operating system hands out permission per app — a shared ceiling covered in Screen Time vs. third-party app blockers.
That is why box ② is worked with the app’s own settings, not the OS:
- Narrow the notifications. Kill everything that isn’t a person writing to you — recommendations, announcements, broadcasts from business accounts. This single step removes more openings than anything else on the list.
- Demote it on the Home Screen. Move it off page one and into a folder. One extra tap is enough to stop most reflex opens (see rebuild your home screen).
- Give yourself a reason to open it. “I open it to reply” is a rule. Without one, checking a message turns into ten minutes of scrolling whatever else is in there.
Menu names inside these apps change with updates, so check the current wording under the app’s own Settings → Notifications rather than trusting a screenshot.
One question to ask a week later
Was the inconvenience caused by an app I blocked, or by an app that got caught in the blast?
- A blocked app was inconvenient → your sort is right. Nudge the limit up a little.
- A caught app was inconvenient → box ① is missing something. Add that one app to box ① instead of tearing the whole setup down.
Job Research Institute’s 2024 survey on smartphone dependence in Japan (606 working adults, fielded 6–11 November 2024) found 77.6% said they want to cut down their phone use — while 88.8% said they feel uneasy in an environment without their phone. Both live inside the same person. Build only for the wish to cut down and it collapses; build only for the unease and nothing changes. Stocking box ① first and then narrowing box ③ is the order that respects both.
One thing to do today: open your Screen Time report and circle last week’s top three.

FAQ
- I want less screen time, but I can't block my messaging app. What now?
- Leave the messenger on the keep side. In MMD Institute's 2024 survey in Japan, the most-named overused app was the messenger LINE (47.3%), but blocking the app everyone reaches you on tends to get the whole setup undone that evening. Block social and video apps by name instead, and quiet the messenger through its own notifications and where it sits.
- Why did Screen Time block my messaging app too?
- Usually because a limit was set on a whole category, and messaging and social apps often share one. Tap into a category to see the apps inside, and pick the apps you want to block individually.
- Can I block one part of an app, like everything except the chats?
- No operating system can block part of an app; permission is handed out per app. Work it through the app's own settings instead: turn off everything that isn't a real message, move the app off the first Home Screen page, and open it only to reply.
