I have been using LightMeter in my iPhone for the last year or so.  Once I understood the protocol, I was able to use the program pretty much as I would use any light meter.  The results are consistent and, as far as I can tell, accurate.  I prefer to use my Sekonic light meter most of the time because it is faster and easier to use but I am glad to have a meter in my phone when I forget to bring the Sekonic.

I've had times where my batteries died far out in the field... I would love to have extra backup plans when I'm out of batteries!

That's why I always carry this thing in my bag:


Expomat
No batteries required

worth a shot, although my Gossen hasn't required a change of batteries in a long time, whereas I only have to look at the iphone to drain it of power.
And with Francois' most helpful link, batteries not required

I also found a slightly different one which requires more work but is more "sensitive" in low light situations...
Besides, it sports the Made in the UK logo

Thanks Francois I've just downloaded the Exposure-Mat it's a very clever little thing.

I've just downloaded the app too! You can't have too many back-up plans.

I use my BB Bold not so much as a light meter, but as a tonality preview.  I shoot B&W and I shoot the subject area in B&W on the phone.  I couple that with my manual metering with my handheld Weston Master IV to decide where I specific portions of the subject area to fall within the film's ranges.
