Is 30 days too short?

I can easily set the trial time longer and have been thinking about doing so.  I figured 30 days would be enough, but then I built the thing so I really didn't need any time.  You have several ways of indicating your preference for the trial period.  E-mail me at support@moodappsllc.com, post to this blog, or let me know via the support page.  You can reply to this via the app, and you can post to the support page via the app.  Let me know what you think.
