Lghtmtr is a beautifully simple light meter that helps you find — and understand — the ideal exposure settings for a scene. Built for film photographers and anyone learning the craft, it makes the relationship between ISO, aperture, and shutter speed feel intuitive and the visual feedback helps reinforce the connection between them. Take a reading, get your settings, and start exploring. Adjust one value and the others respond instantly. Lock settings to experiment and see how each change affects your exposure. You can easily add camera profiles to the app to limit the possible values to what's most relevant to your camera and lens combination. With a visual reference of the scene behind every reading, Lghtmtr helps you shoot with clarity and confidence.

Are you a meticulous film photographer that prefers to record settings/locations for the film photos that you take? Are you looking for a simple and easy to use app for tracking and logging that information? Are you tired of the buggy, crash-prone, or convoluted photo logging apps currently available? I happen to be all of those things. Which is why I developed MetaLog. MetaLog is a simple yet powerful data logging utility for photographers who want to quickly record photo metadata for photo cataloging or EXIF tagging during post-processing. In addition to keeping track of the settings for each photo, MetaLog can also act as an equipment inventory for your gear. Feature Highlights: • See all of your added film rolls at a glance, including the number of frames added to each roll, as well as load/unload dates to show which rolls are still in use. • Quickly log settings for each photo including date, lens, aperture, shutter speed, exposure compensation, as well as location coordinates, accessories, and notes about the shot. • Intelligent pre-fill and filtering for dates, locations, and equipment, making adding new frames a snap. • Easily manage multiple rolls loaded into multiple cameras simultaneously. • Pinpoint photo locations with a simple and familiar pinch-and-zoom map interface. • Export all logged data as convenient CSV files. • Gear pages can record camera and lens models as well as serial numbers, allowing for a complete gear inventory that's handy for tracking and insurance.

Verdict
The clearest difference is price: Lghtmtr at Free against MetaLog's $0.99. Lghtmtr also leads on rating (4.6 vs 3.8) and ratings volume (167 vs 12). MetaLog's advantage is in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 3 months). On ads, device support and iOS requirement there is nothing between them.
