Are there any Android contact apps that do not use the stock Android Contact Storage?
It can include an integrated dialer, or rely on an external one.
I am interested both in options that are completely offline and those that sync to a server.
I am not interested in solutions that require you run your own server, unless it is a push-button server that can be set up on a gratis host in 5 minutes or is a simple server that can be run on-demand. In other words, I'm not interested in solutions that require running your own 24/7 server or paying for hosting just to have a working contacts server.
I prefer gratis solutions, but will consider solutions that have a one-time payment. Please, nothing with monthly service fees.
I prefer something that will allow vCard imports/exports, but this is a preference, not a requirement.
Many thanks to @FONZ for the encouragement to write this question.
