Battery Monitor Guard + Widget
Batterie charge saver alarm
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
* Set an alarm for any charge level and never overcharge. Keeping your battery between 20–80% is the simplest way to protect its long-term health.
* Apple Watch 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.
How it works

Battery Alarm Premium unlocks:
* Ad-free experience
* Premium and system alert sounds
