To give some feedback on this, I ended up going with the light meter app below. The link below it is to Ollinger's light meter collection, which is a real fun web page to peruse because he covers most analog meters known to humans. If you love analog meters, this will be a real treat checking out some of the odd ones he has featured. Some of them are works of art. The app I chose for my Android phone is very much like a traditional analog light meter. It's also free:]
The last thing I wanted was some sort of digital readout display because I find those slow to read and counter intuitive in the way they work. This one works almost exactly like my old Sekonic L 188 meter. So far it seems accurate, but all I have to go on is confirming it's readout using Sunny 16. Low light? I wish I knew! Especially since that's the one purpose I bought it for.
So I bought 3 rolls of film and plan on bracketing the heck out of my shots. Something should work out amongst all those. Went w/ T-Max 100, Tri-X 400, and since I couldn't find any Kodak Gold 200 locally, a roll of Kodak ColorPlus 200. People seem to either hate this film or like it. Looking at samples online was a waste of time, as some looked wonderful and some looked crazy bad. But google Kodak Gold 200 and you will see exactly the same thing, so that means less than nothing.
The general web consensus seems to be that no matter what light meter app you have, it's only as good as your phone. Mine seems pretty decent, so hopefully things should work out. In a sense, this was sort of a not-so-smart way to go, as I could have bought just one roll of film and a better analog light meter for what I paid for three rolls of film (local stores really mark things up compared to buying online), but now I know of at least four stores here in Albuquerque that I can bike to and get some film that day, which is nice when you want something right now vs waiting for it in the mail. I also discovered a store that will develop traditional B&W emulsions for $6 a roll, which enabled me to buy the Tri-X and T-Max instead of relying on desaturating the cheapo Fuji 200 that Walmart carried. They were the ONLY store I could find by the way that sold film besides the photo places I eventually uncovered. Riteaid, CVS, Walgreens, and the local drugstores carried no 35mm film at all, only some disposable cameras.
