Have played around with Locus Free, liked it enough that I got Pro, and have been enjoying Locus extensively...and I use it for geocaching (both geocaching.com AND opencaching.com) AND Munzee-hunting as I can use cached maps (not yet an option with Munzee, unfortunately)...
IMHO, probably the best solution would be possibly a dedicated addon for Locus (similar to the geocaching.com plugin that exists)--the big determiner, I think, would be actually getting an API from Munzee which as of yet doesn't exist (no idea how munzee.dfx.at is batching them save by scraping info--maybe it's just the whole scanning QR codes and virtuals and NFC codes that is the reason an official API isn't out there yet--probably wouldn't hurt an indie developer to ask, at any rate).
Until a dedicated addon happens (that allows live download and reporting), though, doing a Locus-friendly GPX at munzee.dfx.at and then importing (and marking Munzees hidden as they're found) works as a workaround for now.
