Yep, another user here too. It was out about 2/3 compared to my lunasix (my regular, big bulky meter). I've been using the pocket meter to get an idea of if/how a shot will work, but still use my 'real' meter when it comes to the shot (prefer incident in most incidents :P).

One limitation I notice regularly, is that it isn't great in low light. I shoot in low ambient light a fair bit, and tracked down a lunasix years ago for that very reason. Once dusk starts to fall, I find I can no longer find anything to meter off with the app.
