I just took a look at mSecure. I liked what I saw. Definitely not dead, as some theorized earlier in this thread. It supports syncing with iCloud, Dropbox, Wifi, or their own servers.
Currently it is $20 for version 5 Pro, one-time, supports all features on all devices.
I see some complaints on the web about their support, but I like that they respond to negative reviews in the AppStore and that they actively respond on their forum.
They are on the verge of releasing v6, which will be a subscription model, but they say that owners of v5 Pro will be transferred into the Gold level and retain all features that currently exist. They also say that this grandfathering may not last indefinitely. Except for beta testers, more details about the new subscription model and its levels have not apparently been released. The latest discussion is here:
In a recent reply on the Feature Requests section of the Forum it was announced that mSecure 6 would be available soon and that major enhancements we have been waiting for would not be implemented in mSecure 5. Will mSecure 6 be considered a completely new product? Will existing customers be...

I respect everyone's personal choices with regards to payment for software. I tend to agree with one poster in the above-linked thread. If a company lives off one-time purchases, it must always be chasing new customers. That can lead to feature bloat and/or lack of support for existing customers. If customers pay only for upgrades, there again it leads to feature bloat, unnecessary redesigns, etc. There are certainly some companies that have done well with these models, from a consumer's point of view. And many that haven't.
Subscription fees give a company a relatively dependable revenue source. As a consumer, of course, one has to trust that the revenue will be used wisely from that perspective. I'm going to give mSecure a serious look.
