Simple and ok Does what it should, but overexposes 4 stop on the LG Optimus 4X HD, like all other meter apps. I'm only able to use the sensor, but to me it's fine
Good interface, but... No half stops, making the app next to useless.
Automatic Automatic adjustable
Clean Minimal UI, Stable, Responsive, Not glitchy Very great UI, it's the most efficient and minimal of all I tried (i've tried the popular ones beecam, light meter tools, those are not good at all, crummy and cartoony UIs). If it's not accurate as your light meter, don't blame the developer, the meter on our phones are not that good and cannot real light meters, but I find this one resembling the auto exposure values of my Sony NEX, app running on an HTC Sensation. Good for a quick check on incidental light. If you want accuracy go buy a real lightmeter.
Useless Not sure how others tested this "meter" but I got 400 ISO to f2.8 at 1/30... Inside a darkened drawer. Seems more a novelty than anything.
