I'm not connected with it, just came across AppCobra: http://www.appcobra.com/

There's also: https://trigger.io/

What do you think about using such a tool to create apps for mobile devices?

The alternative, it seems, is to have an app created specifically for a certain platform.

We're considering using a wiki to host some internal business processes.

Is there a popular SaaS solution for wikis?

Obviously, the alternative is always to host (and maintain) privately on our server.
