What It Does
Mouthbreather is a desktop app that uses local AI to detect when a user’s lips are open and provide reminders intended to encourage nasal breathing habits. It runs on macOS and Windows and is designed to operate continuously in the background.
The app focuses on awareness rather than treatment. For example, someone working at a computer can leave Mouthbreather running in the menu bar, receive a sound or notification when mouth opening is detected, and review their mouth-breathing streaks and incident statistics later.

Pros & Cons
| Pros | Cons |
|---|---|
| Free to download and use. | It focuses on detection and reminders rather than diagnosing the underlying cause. |
| AI processing runs locally on the device. | The supplied information does not specify detailed hardware requirements. |
| Supports both macOS and Windows. | Detection accuracy may vary depending on camera conditions and user setup. |
| Provides real-time reminders and historical statistics. | It is not a substitute for professional evaluation of persistent breathing problems. |

Alternatives & Comparisons
| Alternative | Best For | Key Difference |
|---|---|---|
| Apple Health | General health and wellness tracking | Broader health tracking rather than computer-based mouth detection |
| Breathwrk | Guided breathing exercises | Focuses on structured breathing exercises instead of mouth detection |
| Oura | Sleep and broader health tracking | Wearable-based monitoring rather than webcam-based detection |
| OpenBCI | Advanced physiological experimentation | Hardware-based physiological sensing rather than habit reminders |
Mouthbreather occupies a narrow niche as a free, computer-based tool for increasing awareness of mouth-opening behavior. Choose it when real-time desktop reminders and local processing are more important than comprehensive health or sleep tracking.
