LoopJuice

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.

No LoopJuice account, ads or third-party analytics. 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.
