What can you use the app for?

JustProto is a service intended to help developers of desktop and web based applications. The user can help bring budget, IT and business requirements together in a way that makes everyone happy. The application is web based and allows users to create a prototype of the application and share them before any work begins. The client can see an interactive prototype that can help them provide valuable feedback from step one of the project. The application is designed to help reduce the chances for miscommunication or misunderstandings, reduce wasted time and keep everyone on the same page. Users can bring multiple collaborators in on a project and work together so that a solid prototype is produced before the user spends any time developing the project. The JustProto website is available in English and Polish.
