I'm sure you're hurting and upset, and I do sympathize, but I don't think you have a leg to stand on. At multiple junctures, you sold assets related to your app, which suggests to me that it was a half-hearted effort, even though you had a coming soon page. There are no unwritten codes in business; only written ones, and sometimes a bigger dog comes in and steals the show.
