LoopJuice
Smart Home 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 batteries that need attention, follow their history and plan your next replacement or recharge.
KEEP YOUR HISTORY TOGETHER
Turn on optional iCloud sync to combine battery history and maintenance information collected on your iPhone and iPad using the same Apple Account. Data stays locally available and syncs through your private iCloud database. Export and import saved data, browse stored history and recover available records. Notification and display preferences remain specific to each device.
SEE WHAT NEEDS ATTENTION
Browse accessories by room or in a grid, with clear battery rings and the lowest readings first. Search, mark favorites, ignore devices and switch between homes. Low and Critical views highlight batteries needing attention. Unreachable accessories with a last known charge above 15% appear muted and do not increase the attention count or app badge. Warnings and the optional badge cover all your homes.
UNDERSTAND BATTERY LIFE
Explore history charts with useful 7-, 30- or 90-day ranges when readings are available. See approximate remaining-life estimates from usable history and indications of unusually fast drain. Real charging status is shown when an accessory reports it. Choose whether a battery is rechargeable to set the default for new maintenance entries, without changing its reported readings.
REMEMBER REPLACEMENTS AND RECHARGES
Record maintenance dates, battery types, quantities, charging methods and notes. Recognizable battery illustrations help identify common types. Reuse details entered for the same manufacturer and model, and compare completed cycles with matching batteries. Work through a maintenance round on iPhone, iPad or Apple Watch, with Undo if needed.
WARNINGS THAT FIT YOUR HOME
Set a default low-battery threshold or customize it per accessory. Enable battery warnings, silence them for 24 hours or choose Remind me tomorrow for an individual accessory.

Requires Apple Home access and compatible accessories that expose battery information through HomeKit or Matter. Some report only normal or low status, and charging information varies. Estimates are approximate. iOS manages background updates; continuous monitoring is not guaranteed. Warnings depend on available readings and notification settings. Optional sync requires iCloud and an internet connection; history depends on previously saved or synced readings. Sharing an Apple Home does not share private history between different Apple Accounts. LoopJuice monitors batteries and does not control accessories.
Ratings & Reviews
LoopJuice 1.6 adds broader Matter battery support, more useful widgets and improvements inspired by your feedback.
• Battery support for more Matter accessories connected to Apple Home, including compatible robot vacuums.
• Layouts that adapt to iPhone Duo, from the compact outer screen to the larger inner display.
• Smoother refreshing when accessories are slow or unavailable, with a spinner while your last readings remain visible.
• A clearer distinction between low batteries and unreachable accessories. Devices last seen above 15% appear muted and no longer count toward attention or the app badge.
• Choose whether an accessory uses a rechargeable battery. Your preference sets the default for new maintenance entries and syncs when iCloud sync is enabled.
• New widgets for maintenance rounds, battery supplies, battery history and charging accessories.
• More battery-type presets: CR2, CR1632, CR2025, CR2430, CR2477, ER14250 (½ AA) and Li-ion, with matching icons.
• More consistent buttons and switches, and guidance for wider Control Center controls.
