Your smoke detector shouldn't have to scream at 3am to remind you it needs a battery. Batteries At Home tells you before it dies — for every gadget that runs on regular batteries, not just the ones with a companion app. Version 2.0 is a complete rebuild: a new dashboard, room organization, an auto-generated shopping list, support for rechargeable batteries, and a cleaner design throughout. WHAT'S NEW IN 2.0 Dashboard — One glance tells you what needs attention today, what's coming up, and what's already stocked in your inventory. Rooms — Group devices by location (kitchen, garage, kids' rooms). Shopping List — Batteries At Home tells you what to buy before your next store run: "4× AA, 2× CR2032" — generated automatically from your upcoming changes. Rechargeable Batteries — Track charge cycles for NiMH and other rechargeables alongside disposables, with replacement guidance that accounts for their shorter lifetime per charge. Device Photos — Attach a photo to a device so you remember which way the battery goes in, or where the tricky screw is, six months later. Siri & Shortcuts — Ask Siri which devices need batteries, or build automations with the Shortcuts app. Redesigned Widgets — Small, medium and large widgets now show device icons directly in the battery ring, with a cleaner layout at every size. CORE FEATURES - Device Inventory — track every battery-powered gadget in your home: remotes, smoke detectors, toys, and anything in between. - Smart Predictions — the app learns from your actual change history to predict when a battery will run out, and gets more accurate over time. - Battery Inventory — keep track of the spare batteries you already own; they're pulled from stock automatically when you log a change. - Custom Battery Types — beyond AAA, AA, C, D, 9V and coin cells, define your own. - iCloud Sync — your data follows you across iPhone and iPad. - Home Screen Widgets — see what's due without opening the app. FREE VS. POWER USER Batteries At Home is free to use for up to 3 devices, with all core tracking features included. Power User unlocks unlimited devices and custom battery types, as a one-time purchase or subscription — whichever fits how you use the app. Reduce waste, stop digging through drawers for the right battery, and never get caught off guard by a dead remote again.
