Lightme - Lightmeter

Lightme - Lightmeter is a clean, simple yet powerful lightmeter optimized for one-handed use. Its stretched-needle interface shows multiple valid aperture and shutter-speed combinations at once, so you can pick settings quickly without endless wheel scrolling. It works for both left- and right-handed users and keeps core controls within your thumb's reach.

It includes a rich feature set for beginners and seasoned shooters: continuous metering; spot metering with adjustable zoom and zone-system support; automatic reciprocity failure compensation for long exposures; a dedicated pinhole mode with multiple apertures and optional timing; incident metering with front-facing camera calibration. It also offers black-and-white preview, camera-swapping, presets, framelines, tips and a library of over 70 films, dark mode, and deep customization. The app is free to use with optional IAPs to support the project.
