README
redeye
A macOS menu bar app that tints your display red as your battery runs low — so you never get surprised by a dead laptop.
## How it works
When your battery drops below ~10%, redeye fades a red overlay across all connected displays. The overlay intensifies as the battery drains further. Plugging in clears it immediately.
## Features
- Red overlay that intensifies with battery drain
- Multi-display support
- Launch at login
- Auto-updates via Sparkle
- Optional menu bar icon
## Install
Download the latest `redeye.dmg` from the [Releases](../../releases) page and drag app to your Applications folder.
> **Note:** Release builds are ad-hoc signed (not notarized). On first launch, go to **System Setting** -> **Privacy & Security** -> **Open Anyway**
>
> 
> 
## Development
```sh
make setup # install swiftlint + swiftformat, activate git hooks
make preview # kill any running redeye, build Release, open the app
```
`make setup` only needs to be run once per clone. It installs the required tools via Homebrew and points git at the `.githooks/` directory, which runs SwiftFormat + SwiftLint on commit and a Debug build on push.
## Requirements
- macOS 13 Ventura or later
