"Yapp App Does the Job at a Reasonable Price. The ease of set up was awesome! We are a small board and were worried about how much time it would take to set up our conference but really it was just a couple of hours and we set up all the information. We were pleased to have a place for our attendees to share thoughts and pictures in real time."
Aurie Clifford Assistant Director Mid-Market (51-1000 emp.)
"Yapp is an economical and extremely versatile application to enhance your business conferences. Setting up a Yapp can be mostly done by non-technical administrative personnel. We have conferences with thousands of attendees and use the formatted content in the about section of the import template to publish personalized agendas, complete with map links directly into Yapp."
Phil O'Brien-Moran Senior VP Technology Enterprise (> 1000 emp.)
"Wonderful experience with all the bells and whistles needed with an affordable price tag. I loved the user-friendly interface and how easy it is to use. It included all the items I needed - schedule, sponsors, attendees, etc. We use to print a conference booklet, but decided to switch to the mobile platform this year."
Courtney Whaley Board Member Mid-Market (51-1000 emp.)
"We were quoted $22K from Cvent and $18K from Whova. Built our app on Yapp in 45 minutes for $450."

The Bad Seed | !full!
The film is a masterclass in suspense precisely because it asks the audience to confront an impossible reality. We watch Rhoda sweet-talk adults while her mother unravels. The most famous scene—the "closet scene"—remains one of the most unnerving in classic cinema. Christine confronts Rhoda, who responds with a flat, reptilian rage: "I had to think... I had to reason... I had to plan." The use of adult dialogue delivered by a child in a party dress creates an uncanny valley effect that modern horror movies still try to replicate.
There are few tropes in literature and cinema as chilling as "The Bad Seed." It is a concept that pierces the very heart of our cultural comfort zone: the sanctity of childhood. We are conditioned to believe that children are blank slates—innocent, pure, and untainted by the world. They are the victims of horror stories, the ones to be saved from the ghosts in the closet or the monsters under the bed. The Bad Seed
March’s novel introduced the controversial theory of "psychopathic innate evil." Unlike the "nature vs. nurture" debates of the time, March leaned heavily on "nature." Christine discovers that she was the daughter of a famous serial killer who died in the electric chair. The novel suggests that violence is encoded in the blood, passed down like eye color. This was shocking for the 1950s—an era of post-war optimism and Dr. Spock parenting guides. The idea that a well-loved child in a suburban home could be a monster was a direct assault on the American Dream.
The novel was a bestseller, but it was the 1954 stage adaptation and the subsequent 1956 film that cemented Rhoda Penmark in the pop culture pantheon.
The legacy of The Bad Seed is visible in nearly every modern horror film featuring a malevolent child. From The Omen and The Exorcist to more modern takes like Orphan and We Need to Talk About Kevin, the DNA of Rhoda Penmark is present. It forces the audience to confront a terrifying question: what do you do when the person you love most is a monster you cannot fix?
