## What is Battery Sink?

Battery Sink shows the battery level of all your Apple devices in one place. Check your Mac from your iPhone, your iPhone from your Watch, or everything at once from a widget.

EVERY DEVICE, EVERY SCREEN
• iPhone and iPad battery, reported by the app on each device
• Mac battery, from the Mac app, which keeps reporting with its window closed
• Apple Watch battery, through the Watch app and your paired iPhone
• Bluetooth accessories that share their battery with apps, such as many keyboards, mice, trackpads and game controllers, while connected to an iPhone, iPad or Mac running Battery Sink

WIDGETS
• A large widget for your iPhone and iPad Home Screen and your Mac desktop
• Watch face complications and Smart Stack widgets on Apple Watch
• Choose which devices each widget shows, and in what order

LIVE UPDATES
• Readings update live while the app is open, and the Mac stays connected
• Charging state at a glance
• Low-battery alerts at 20%
• A "Report Battery" Shortcuts action, so a locked iPhone can report when you plug it in or when its level changes

PRIVATE BY DESIGN
• No sign-up, no email, no ads, no tracking
• Your devices are linked by a 12-digit account code that only you share
• Delete your account from Settings at any time

ONE PURCHASE
Buy once and use Battery Sink on your iPhone, iPad, Mac and Apple Watch.

WHAT IS NOT SUPPORTED
AirPods, Beats, and most other Bluetooth headphones and speakers are not supported. Apple does not allow third-party apps to read their battery level, so Battery Sink cannot show them. Accessories only appear while they are connected to a device running Battery Sink, and some report 0% to apps even when charged.

iOS decides when apps run in the background, so a locked iPhone may report less often unless you set up the Report Battery shortcut. Each device needs Battery Sink installed to report its own battery. An internet connection is required to sync.
