# Screen time by app: finding your most used apps on iPhone

2026年6月9日 · 3分で読めます · finitの開発チームより

The daily total is a headline; the per-app list is the story. Which app actually eats the hours is the question that decides what, if anything, you change, and the iPhone answers it in one screen most people have never scrolled. Here is where the list lives, how to read it without fooling yourself, and the one thing it can't tell you.

## Where the per-app list lives

Open **Settings → Screen Time → See All App & Website Activity**. Below the chart sits the ranked list: your most used apps, top to bottom, for the selected week or day. Tap any app for its own chart, its daily average, and its notification and pickup counts. The **Week** and **Day** tabs change the period; the arrows page backwards through [the roughly four weeks the phone still holds](https://getfinit.com/ja/blog/screen-time-history).

## Categories versus apps

The list can group by category, and categories flatter you. An hour of YouTube inside a browser lands under the browser; a category label like productivity can hide the one app inside it doing the damage. When the list shows categories, tap through to the apps themselves before drawing conclusions; the honest unit of this exercise is the single app, not Apple's genre for it.

## Reading the ranking honestly

Three habits make the list useful instead of alarming. Compare full weeks, not single days, because one long evening reorders everything. Watch the top three over time rather than the exact minutes; ranks are stabler than totals. And note the strange entries before assuming a bug: system screens and utilities appear in the list too, because Apple counts them the same way it counts everything else. If a number still looks impossible, [here is why Screen Time looks wrong](https://getfinit.com/ja/blog/screen-time-wrong).

## The part the list can't answer

The per-app view answers this week convincingly, and last month not at all: the ranking only exists as far back as the rolling window reaches. Whether Instagram's grip is loosening since spring, whether the podcast app really replaced the feed, whether the top three has changed in a year, those are per-app questions across months, and the phone deletes the evidence. finit keeps the per-app record beyond the window, which turns the ranking from a snapshot into a trend you can actually check.

## 短い答え

### How do I see my screen time by app?

Open Settings, tap Screen Time, then See All App & Website Activity. The ranked list under the chart shows each app's time for the selected day or week, and tapping an app opens its own breakdown.

### How do I find my most used apps on iPhone?

The same screen is the answer: the activity list is sorted by use, so the top of it is your most used apps for that period. Switch between Week and Day to see whether the ranking holds or was one unusual evening.

### Why do the categories look different from the apps?

Categories bundle apps by Apple's labels, so one heavy app can hide inside a mild-sounding group, and web use lands under the browser. For honest conclusions, read the individual apps rather than the category totals.

### Can I see my most used apps from months ago?

Not from the iPhone; the per-app detail is deleted with the rest of the history after about four weeks. Months-long comparisons only exist where something recorded the days as they happened, the way finit imports them into a lasting record.

The ranking this week is information; the ranking across a year is self-knowledge. [Keep the list long enough to learn from it](https://getfinit.com/ja/why).
