What App? Mylightmeter (pro) has been dead on accurate for me. Even in snowy conditions etc its worked.
I used the Viewfinder app, mainly because 1) it has rangefinder framelines, which I find useful for pre-framing the shot and getting an exposure, 2) it actually has a decent emulation of several films, including the one I was using, 3) you can snap a photo with it and it'll save all the exposure information, and 4) you can add notes.
I wanted something to document my exposures on my first few rolls of film so I could compare with the photos I got back from the lab and learn from my mistakes. The phone versions of my photos were mostly better-exposed than the film shots, even though I used all the same settings (ISO, aperture, shutter speed). I generally exposed for darker areas like the ground and erred on the side of overexposing, but still a lot of my shots were underexposed. Once I switched to a camera-mounted meter, those rolls came out much better (except for my first B&W roll, which again was badly underexposed and I only had a couple of usable shots from it).
We'll see how my next rolls come out!
