Hi Flavia,
I have never heard of Attend.com so I can't speak to that but what I can say is that sometimes, app developers try to get around the security review and/or prices associated by having you download the package directly from their website. If they are having you download a package directly from their website you may want to look into them. I am not saying that is the case by any means, just a friendly caution.
