LoopJuice
HomeKit Battery Monitor
Free · Designed for iPad. Not verified for macOS.
Your smart home's batteries, in one place.
LoopJuice helps you keep track of battery-powered accessories in Apple Home. Find devices that need attention, understand battery life, and plan your next replacement or recharge.
Browse accessories by room or switch to a grid on iPhone and iPad. See battery percentages in clear circular indicators, with the lowest readings first within each room or across the grid. Search, mark favorites, hide ignored devices, and switch between your Apple homes. Redundant room names are removed from display names without renaming anything in Apple Home.
Separate Low and Critical views help you spot batteries that need attention, including unreachable accessories. Open a combined attention overview or enable an app icon badge. When an accessory reports that it is charging, LoopJuice shows its charging status with a subtle animation.
Follow battery levels with interactive history charts and 7-, 30- or 90-day views when relevant readings are available. Get approximate remaining-life estimates from usable history and spot unusually fast battery drain.
Keep a local log of replacements and recharges, with the latest dates visible in each accessory's details. Record battery type, quantity, charging method and notes. Reuse battery details you previously entered for the same manufacturer and model. Compare completed cycles with matching battery types and quantities, and see the average time between recorded changes.
Work through a maintenance round on iPhone, iPad or Apple Watch. Record replacements or recharges as you go, with Undo if needed. Set a default low-battery threshold or customize it per accessory. Enable warnings, silence them for 24 hours, or choose Remind me tomorrow for an individual device. Warnings and the optional app badge cover all your homes.
Use Siri and Shortcuts to check low batteries, find the lowest battery or see what needs attention. The Apple Watch companion shows the latest information received from your iPhone, including favorites, attention items and available remaining-life estimates.
Your history and preferences stay local. No LoopJuice account, backend, ads or third-party analytics. Made for iPhone and iPad, with an Apple Watch companion, light and dark appearances, and English, Dutch, Spanish, Portuguese, French and German.
Requires Apple Home access and accessories that share battery information through HomeKit. Some report only normal or low status, rather than a percentage. Charging information varies by accessory. Estimates are approximate. Background updates are managed by iOS; continuous monitoring is not guaranteed. Warnings depend on available readings, settings and notification permissions.
Keep your batteries close with configurable widgets and quick-opening controls:
• One accessory: focus on a single battery.
• Two accessories: show two batteries side by side, with shared or separate selection settings.
• Multiple accessories: four battery rings or a larger overview.
• Battery overview: see how many batteries are in good condition or need attention.
• Running low soon: prioritize available remaining-life estimates, with battery percentages as a fallback.
• Choose Automatic, Lowest batteries, Favorites or specific accessories where supported.
• Set each widget or control to one home or all homes.
• Add small, medium and large Home Screen widgets, plus extra-large layouts on iPad.
• Choose circular, rectangular or inline Lock Screen widgets, and use widgets in StandBy.
• Add Apple Watch complications and Smart Stack widgets.
• Use Control Center controls to open an accessory or the attention overview on iOS 18 or later.
• Explore supported shapes and sizes in the in-app widget gallery. Availability varies by device and widget type.
