Need a longer trial period – SkyCandy - Sunset Forecast Review

I have the trial version. You can only see as far as the very next sunrise or sunset so there really is no way to get a fair test of the apps ability to forecast any further out than a few hours. I cannot evaluate whether or not it's worth buying with such a small preview window. Why not allow one week with full features? If I'm going to commit to a monthly subscription, I want to know before I buy. Thanks.
