This app is currently in development, though is available downloaded and used; if you want to work on this app there's available the appJar module (http://appjar.info/) aswell as Pexels unoficcial API wrapper (https://github.com/salvoventura/pypexels). Both of them are well documented so give it a try! :)
The objetive of this app is to create an intuitive GUI for downloading a lot of images at once from Pexels. It's meant to be a very simple project.
TODO: 
  Make it a bit prettier :)
You can get your API key from https://www.pexels.com/api/new/
