Deadliner is a mobile application which was created to help people with busy schedules (for example, university students and office workers) track and control their deadlines by providing a unique approach of visual progress tracking. The app is available on the App Store for free. Deadlines sync seamlessly via iCloud and can be instantly shared with other people. Deadliner also supports iMessage to make this process even easier. Deadliner reminds the user when there is not much time left before the deadline using push notifications and aggregates all the info in the Today extension. Deadliner also has native Calendar app integration, to make planning even easier for those who use other planning apps as well. The world needs Deadliner, because it connects three main aspects of the work process: planning, progress tracking, and motivation. Only in combination they are able to make the work process truly productive for every person: from college student to office worker.
