Batt-Man

Rechargeable batteries vanish into remotes, clocks and toys for years. Batt-Man remembers which ones are where and how long they have been in. No account, no internet.

Batt-Man remembers where your rechargeable batteries went.

Rechargeables are expensive, and they disappear into remotes, clocks and toys for years. Batt-Man keeps track so you don't have to.

KNOW WHICH BATTERIES ARE WHERE Add each gadget with a photo and its spot in the house. See at a glance what's inside it.

SEE HOW LONG THEY'VE BEEN IN Green, amber or coral: a traffic light tells you when a device is overdue for fresh batteries.

SWAP THEM IN TWO TAPS Pick the device, tick the batteries going in. The old ones move to Charging on their own.

EVERY BATTERY, AT A GLANCE Each battery gets a number like AA-01 (write it on with a marker!). Ready, In use, Charging or Retired: always sorted.

CHANGE PHONE, KEEP EVERYTHING Back up to a file, restore on your new phone. No account needed.

BIG, CLEAR AND SIMPLE Large text, big buttons, tap chips instead of typing. Made for everyone, including eyes that prefer bigger print.

YOURS, PRIVATELY Everything stays on your phone. No sign-up, no internet, no tracking. Works with AA, AAA, C, D and 9V batteries.
