## What is Battery Monitor Guard + Widget?

Your iPhone battery degrades every time you overcharge it. Battery Alarm fixes that.

Set a threshold — 80% is the sweet spot — and get a loud, unmissable alarm the moment your battery hits it. Plug in, walk away, and trust Battery Alarm to tell you when to unplug. No more compulsively checking. No more degraded battery capacity after a year of overnight charging.

What's new in version 3.0

* Battery Alarm has been completely rebuilt from the ground up.
* Brand new design — dark, premium, and built around a clean amber and navy visual language. Every screen redesigned.
* Apple Watch app — set and cancel your alarm directly from your wrist. Adjust your charge threshold using the Digital Crown. No need to reach for your phone.
* Apple Watch complication — see your iPhone's battery percentage directly on your watch face. Your iPhone charge level, glanceable on your wrist at any time. This is not something Apple provides natively — Battery Alarm brings it to your watch face.
* Home screen widgets — three sizes. See your target charge level and alarm status without opening the app.
* Lifetime purchase — a one-time payment that unlocks everything, forever. No subscription required if you prefer to pay once.

### 1/5 — Worthless

*2026-02-19*

About the only thing this app was really good at was forcing you to watch one video advertisement after another every time you switched to the app . Had the app sitting there with nothing else running and it charged a 90% and never gave me a warning! Painful…😠

### 5/5 — Perfect

*2025-12-03*

Performs exactly as described, thank you so much!

### 1/5 — Disappointed

*2025-12-01*

Not as described. I need “low battery” alarm for wife’s phone. This only applies to charging.

### 2/5 — Did not signal alarm

*2025-03-16*

Alarm set at 80%, charging went to 85%. I was monitoring it so as not to overcharge.

### 5/5 — Reliable app

*2024-09-15, version 2.2*

Works really well, it’s very reliable. One of the best apps in its category and easy to use interface.

### 5/5 — It works reliably.

*2024-09-12, version 2.1*

The app works reliably. Not many apps in this category do what they claim. But this one works just as expected. Simple clean UI. Good work.
