We'll agree to disagree. I think it's questionable enough that Dan felt independent evidence was necessary beyond Sam's actions. Also, the plot can't be driven if Carly and Freddie don't wrongly suspect that she's in love with Brad. The Mood App helps do that.

Look how many online fans who don't like the Seddie ship were trying to convince themselves that Sam was really Melanie, or she was still messing with him, or she kissed him for some other reason beyond being in love. And that was WITH the Mood App in the plot! Imagine how much more ambiguous it could have been without it.
