## Review summary

Users find that the app works on certain devices and continues recording with the screen off, offering a basic motion detection camera that feels relatively secure. However, multiple reviews report critical issues including crashes upon motion detection, failure to save videos to SD cards, delayed recording start, poor video quality, and missing features like sensitivity adjustment and landscape recording. While some users appreciate its simplicity, common technical problems significantly impact usability.

### Pros

- Works well on some devices, including older models.
- Continues working even when the screen is off.

- Automatically detects motion to start recording videos.
- Generates multiple short video clips to cover motion events.

### Cons

- Inability to save videos to SD card on some devices due to storage location issues.
- Frequent crashes or stops recording after detecting motion.
- Poor video quality such as low frames per second, darkening on motion, or blurry captures.
- Delay in start of recording after motion is detected, missing initial seconds.
- Lack of important features like sensitivity settings, timer before monitoring, and landscape recording mode.
