Hi Tracy,
I understand your frustration, and believe me, it's something I've felt myself. Our 4.0 update was kicked back a few times, and we received replies each time with a week or so. The latest version we sent (with fixes) was uploaded over 3 weeks ago now, and we've heard nothing. We have sent emails several times, but have not heard any response.
In the meantime, Apple has released other (paid) versions, which are essentially the exact same program (but with different content.) This makes it look like we're trying to "boost sales" and nothing could be further from the truth. The only reason we have released other versions in the App Store is to make it easy for our users to grab the version they want, simply and quickly. It's to make things more flexible, and to increase the awareness of the other Bible translations we offer. Many people didn't have a clue that we even offered an NASS version, or a MSG, or whatever. Now, hopefully, they'll know.
As far as competition -- we're not in a race here. There are some other great programs out there, and we fully respect them. Our goal is not to "out-sell" anybody (for how could we ever be upset by people reading God's word?) Our goal, rather, is just to make the best possible Bible Study Software that we can.
