Why does my step widget show an old number?

Because iOS decides when a widget may refresh, not the app. Apple's documentation describes a daily budget of roughly 40 to 70 refreshes for a widget someone looks at often, which works out to a reload every 15 to 60 minutes. The 24-hour window is tuned to your own usage pattern rather than resetting at midnight. Opening the app refreshes its widget immediately.

Can I make a widget update in real time?

No. No iPhone app can, and any app claiming a live-updating home screen widget is describing something iOS does not allow. A widget is a snapshot the system redraws on its own schedule. If you want the number moving as you walk, open the app.

Home screen or lock screen — which step widget is better?

The lock screen one is seen far more often, because most glances at a phone never get past the lock screen, but it is tiny and can only show a number or a short line. The home screen widget has room for the number plus context such as distance or a streak. Many people use both.

Does a step widget drain the battery?

Not meaningfully. The widget is not counting anything — the iPhone counts steps itself, on low-power motion hardware, whether or not any app is installed. A widget only draws the number that already exists, a few dozen times a day.

your step count on the home screen

A step widget puts today's count where you already look, so you don't have to open anything. Press and hold the wallpaper, tap Edit, then Add Widget, and pick the app. The one thing worth knowing before you start: iOS decides how often a widget may refresh — not the app — so the number is sometimes a few minutes behind, and that is normal rather than broken.

Adding one, in four steps

Press and hold an empty part of the home screen until the icons jiggle.
Tap Edit in the top left corner, then Add Widget.
Search for the app by name, or scroll to it in the gallery.
Swipe between the offered sizes, tap Add Widget, drag it where you want it, and tap Done.

The lock screen is its own path, and it has its own page: how to put steps on the lock screen walks through it — the two slots, which one a step count actually fits in, and the iOS 26 change that lets you drag the widget frame down within reach of a thumb.

Why the number is sometimes behind

This is the question people actually ask, and most apps answer it with "it updates automatically", which explains nothing. Here is the real mechanism.

A widget is not a small running app. It's a picture the system draws from a timeline the app hands over in advance, and iOS chooses when to ask for a new one. Apple's own documentation puts the daily budget at roughly 40 to 70 refreshes for a widget someone looks at often — about one reload every 15 to 60 minutes. That 24-hour window is tuned to your own habits rather than resetting at midnight, and the system weighs things like whether you've opened the app recently.

So a widget showing a number from twenty minutes ago is behaving exactly as designed. What reliably brings it up to date is opening the app — that lets the app hand over a fresh timeline immediately.

No iPhone app can do better than this, and one that claims a live-updating home screen widget is describing something iOS does not permit. If you want the count moving as you walk, that happens in the app, not on the home screen.

What makes a step widget trustworthy

Two things, and only one of them is visible.

Where the number comes from. On iPhone, steps are counted by the phone itself, on low-power motion hardware, and collected in Apple Health, whether or not you have any step app installed. A widget that reads Health shows the same number as the Health app, your Apple Watch and every other app that does the same. A widget that keeps its own private count will slowly disagree with all of them, and there is no way for you to tell which is right.

Whether the widget reads it directly. A widget that can only show what the app last saved goes stale whenever you haven't opened the app. One that reads Apple Health itself is right as soon as iOS lets it redraw — the same 15 to 60 minutes, but with a true number at the end of it.

Battery

A step widget doesn't measurably cost battery. It isn't counting anything: the iPhone counts your steps regardless, on hardware built to do it for almost no power. The widget only draws a number that already exists, a few dozen times a day.

Home screen or lock screen

The lock screen widget is seen far more — most glances at a phone never get past it — but it's tiny, and it can hold a number and little else (putting one there takes about forty seconds). The home screen widget has room for the count plus some context: distance, calories, a streak, a week at a glance. Neither is better; they answer at different depths. Plenty of people keep both.

The Angel Step widget

Ours reads Apple Health itself, so it doesn't wait for the app to be opened, and it shows the same count your iPhone already agrees with. It comes in both places — home screen and lock screen — and the home screen one puts the number on the same living sky the app uses, so the two never look like different products.

It isn't on the App Store yet. The honest description of the whole app, including what it deliberately doesn't do, is on the about page, and if you want to know what a goal like 3333 steps means in distance and minutes, that's on how far is that many steps.
