YouTuber David Dobrik?s new smartphone app hit 1 million downloads in less than a month. The app, David?s Disposable, mimics the experience of using a disposable camera. According to Business Insider, not only does it look like a disposable photo, but they take time to ?develop.? Users can only see photos after 9 a.m. the next day and can also order prints of the photos. David?s team said the app became popular because people can?t pretend to be perfect with these photos.
