## Description

**Light Meter** is a user-friendly exposure calculator designed to help photographers achieve the perfect shot. By using your phone's main camera sensor or front ambient light sensor, it calculates ideal shutter speed based on your chosen ISO speed and aperture settings. The app features priority mode by tapping to lock aperture or shutter speed, zoom-based metering via pinch or menu, and a Snap function for easy parameter setting.

Additional conveniences include note-taking to save your entire shooting process, backup features for your notes, a Black & White mode to preview your photos in real time, and a Film Stock selection to match the type of film you use. Light Meter is regularly updated with new features to enhance your photography experience.

## Review summary

Users appreciate the app's simplicity and usefulness for film photography and other light-dependent tasks. The layout is straightforward and ads are minimally intrusive. However, many complain about inconsistent and inaccurate light readings, discrepancies between sensors, and lack of memory for settings like film ISO. Some users find the ad system annoying or the app unresponsive. Overall, it's a basic tool favored by film photographers but has limitations in accuracy and user experience.

### Cons

- Readings can be inaccurate or inconsistent, especially indoors or under non-ideal lighting
- Light sensor and camera give vastly different lux readings

- Contains ads that some users find frustrating, such as having to watch ads to remove other ads
- Sometimes unresponsive or stuck at a constant lux reading
