A macOS menu bar app that tints your display red as your battery runs low — so you never get surprised by a dead laptop.
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.
- Red overlay that intensifies with battery drain
- Multi-display support
- Launch at login
- Auto-updates via Sparkle
- Optional menu bar icon
Download the latest redeye.dmg from the Releases page and drag app to your Applications folder.
