Battery Inventory for iPhone and iPad

Never look up the 4LR44 again.

Battery Inventory remembers which battery every device in your home takes, reminds you when one is due, and counts the spares in your drawer, so you buy the right cell before the old one dies. The finder in the app knows every code on this page. Search any of them, or point the camera at a coin cell to read it.

  • Battery change reminders, free
  • Monthly smoke and CO alarm test reminders
  • A spares drawer and shopping list
  • Cordless tool packs and chargers too

No account needed. Smoke and CO alarm features are reminders only: the app can't see or test your alarms.
