## Description

Easily display, improve, and modify your device's screen refresh rate with this comprehensive Chrome extension. It provides a real-time dashboard showing your current screen refresh rate, detects whether your display is static or dynamic, and identifies if you have a game-ready display like 120Hz or 144Hz.

Features include a Notification Hz service to show real-time screen frequency, an On-Screen Display (OSD) for live FPS/frequency display during navigation or gaming (paid feature), detailed display information and specifications, an optimization tool to clean unused data for better FPS, and the ability to force custom refresh rates on supported devices (e.g., Galaxy S20 series). Additional features are planned for future updates. Perfect for gamers and anyone keen on monitoring or adjusting their screen's performance.

## Review summary

Reviews praise Hz monitoring and gaming usefulness when it works, but reliability issues and ads dominate feedback. Users report not functioning in-game, incorrect readings, and premium restrictions hindering access to 120Hz. Overall, the app is helpful but has significant ad and reliability friction.

### Pros

- Displays and verifies the device's refresh rate, including differences between 60Hz and 120Hz.
- Generally good performance and useful for gaming; provides clear Hz information.
- Helps confirm real-world Hz behavior of the device.

### Cons

- Intrusive ads, including ads after paying.
- Not reliable: not working in-game and some readings appear incorrect or inconsistent.
- Overlay/features locked behind premium; unlocks for 120Hz are not consistently available.
- Difficulty unlocking 120Hz or misreading dynamic vs undynamic sensor data.
- Bug: not showing frames when exiting the app.
