Dryfta is an Android-based event app developed by Landshark Labs. The app is free and falls under the Business and Productivity category. Attendees can use the app to update their profile, manage their personal schedule, and check-in to sessions. They can also set up one-to-one meetings with fellow attendees, view sponsors and exhibitors, and engage in discussions on the forum.

Guest users can sign up using Facebook or the registration form. They can view attendees and speakers, as well as their publicly available details including submitted abstracts and checked-in sessions.

Exhibitors can use the app's in-built QR code scanner to scan attendees' QR code on their badges and save them to their list of vCards (leads). Later, those vCards can be exported into Phonebook or in Excel format.

The app is user-friendly and easy to navigate. It provides a comprehensive platform for event attendees to manage their schedule and network with others. The exhibitor feature is a great addition, making it easy for them to collect leads. Overall, Dryfta is an excellent app for event management.
