Log water from your Home Screen and Lock Screen

2026-10-30

The fastest way to log water on iPhone is an interactive widget: a button on your Home Screen that adds a glass with one tap, without opening the app. Since iOS 17, widgets can have working buttons. Add a water widget with a + button to your first Home Screen page, put a progress gauge on your Lock Screen, and logging becomes a single tap you barely notice.

Why widgets make tracking easier

Every step between "I drank something" and "it's logged" is a chance to forget. Opening an app means unlocking, finding the icon, waiting, tapping a button. A widget cuts that to one tap on a screen you already look at dozens of times a day.

Widgets also work as a quiet reminder. Seeing a drop that is half full at 3 p.m. nudges you toward the kitchen without a notification. That combination of a visible cue and an easy action is the core of building any habit, which we explore in how to make drinking water a habit.

Types of water widgets on iPhone

Not every widget can do everything. Here is what each place is good for, using Water Tracker's widgets as an example.

Home Screen: log and see progress

• Small widget: today's total, a filling drop and a + button that logs one glass.
• Medium widget: a bigger drop and two buttons: one glass, and a 500 ml (about 17 fl oz) bottle.

Tapping + logs the drink immediately. The widget updates, the drink reaches Apple Health if you have turned that on, and it syncs to your Apple Watch.

Lock Screen: see progress at a glance

Lock Screen widgets are smaller and show information rather than buttons:

• Circular: a gauge that fills toward your goal.
• Rectangular: your total and goal with a progress bar.
• Inline: a line of text above the clock, such as "5 of 10 glasses".

Tap one to open the app and log from there.

StandBy: on your desk or nightstand

When your iPhone is charging on its side, StandBy can show widgets in full screen. A water widget there is easy to read from across your desk while you work.

How to add a widget to the Home Screen

From Apple's guide to adding and editing widgets:

1. Touch and hold an empty area of the Home Screen until the apps jiggle.
2. Tap Edit in the upper-left corner, then Add Widget.
3. Search for the app (for example "Water Tracker").
4. Swipe to choose a size, then tap Add Widget.
5. Drag it where you want it and tap Done.

Where to put it: on your first Home Screen page, within reach of your thumb. If space is tight, add it to a Smart Stack with other widgets you use; the same guide explains stacks.

How to add a widget to the Lock Screen

1. Touch and hold the Lock Screen until Customize appears, then tap it.
2. Tap Add Widgets.
3. Find the app in the list, then tap or drag the widget you want onto the Lock Screen. If there is no room, tap the remove button on another widget first.
4. Swipe down on the widget list and tap Done.

The circular gauge is a good choice: it takes little space and shows your progress every time you pick up your phone.

How to use a water widget in StandBy

Apple's StandBy guide explains the basics:

1. Go to Settings > StandBy and make sure it is on.
2. Connect your iPhone to a charger, lock it and set it on its side, keeping it still.
3. Swipe left or right to reach the widgets view.

To change which widgets appear, unlock your iPhone in StandBy, touch and hold a widget stack, and add the water widget. If you tap + from StandBy, your iPhone may ask you to unlock it first.

Tips for getting the most from widgets

• Match the button to your glass. The + button logs your glass size. Set it in the app's Settings to the glass or mug you actually use (Water Tracker offers 150 to 500 ml, about 5 to 17 fl oz).
• Use the medium widget if you drink from bottles. The second button logs a 500 ml bottle in one tap.
• Combine a Home Screen widget with a Lock Screen gauge. One makes logging easy; the other keeps progress visible.
• Pair it with reminders that know when to stop. A widget handles the "easy action" part; a gentle reminder covers the moments you forget. See water reminders that actually work.
• Undo from the app. Widgets don't have an undo button. If you tap by accident, open the app and tap Undo.

Troubleshooting

• The app doesn't appear in the widget list. Open the app once after installing it, then try again.
• The widget shows yesterday's total. Widgets refresh on a schedule set by iOS. Water Tracker's widget resets at midnight and updates when you log; opening the app also refreshes it.
• Tapping + seems to do nothing. The widget can take a moment to redraw. Open the app to check before tapping again, so you don't log the same glass twice.

Bottom line

A widget turns water tracking into a one-tap habit. Put an interactive widget with a + button on your Home Screen, add a progress gauge to your Lock Screen, and consider StandBy if you work at a desk. Water Tracker's widgets are free, and the drinks you log from them reach Apple Health and your Apple Watch just like drinks logged in the app. For other quick ways to log, try Siri, Shortcuts and the Action Button.
