Device Battery Manager
Stop guessing which battery goes in which device.
About the App
The right battery, every time.
Device Battery Manager lets you log every device you own alongside the exact battery type it needs — so the next time you're standing in the battery aisle, you already know what to grab. Track replacement dates, add custom notes, and keep every remote, toy, and gadget powered without the guesswork.
Features
Your home battery reference, organized
Log every device and its battery
Build a complete home reference — name each device and record the exact battery type it uses, from AA to CR2032 and beyond.
Never buy the wrong size again
Check the app before you head to the store. The right battery type is always one tap away — no more guessing or buying duplicates.
Track replacement dates
Record when you last swapped batteries so you know which devices are overdue — before they die at the worst moment.
Custom notes per device
Add model numbers, quirks, or any detail that helps — so future-you always has the full picture when something needs attention.
Fully private, fully offline
No account, no cloud, no third-party access. All your data stays on your device — simple, secure, and always available.
iPhone and iPad optimized
A clean, native experience on every Apple screen — fast to open, easy to update on the fly while you're at the store.

Technical Highlights
Stack
Built entirely in SwiftUI for a polished, native iOS interface — fast to navigate and comfortable in both light and dark environments.
SwiftData handles all local persistence with efficient queries and reliable on-device storage — no backend, no network dependency.
MVVM architecture keeps the data model cleanly separated from the UI layer, making future feature additions straightforward.
Zero third-party dependencies — the app is self-contained, fully offline, and has no external points of failure or data exposure.
