🔋 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.
Works with AA, AAA, C, D and 9V — rechargeable or not.
Everything stays on your phone. No account, no sign-up, and no internet connection required.
Know which rechargeable batteries are in which device — and for how long.
