Pros
Pro Awesome team collaboration features
myBalsamiq has been built with teams in mind and has a variety of featured to support collaborating on the mockups:
• Notifications - Real-time notifications to enable you to keep track of team member actions
• Revision Control - All mockups have a revision history to enable reverting to previous versions and keeping track of design decisions.
• Skype Integration - Easy to use Skype integration to host design reviews.
• Access Control - Access controls allow sharing projects with team members as well as allowing external reviewers to leave comments on the designs.
Pro Clean and easy to use interface
Balsamiq has a very easy to use drag and drop interface that lets you quickly build and adjust your mockups. The UI is centered around low-fidelity wireframes that help focus the reviews on the core layout and functionality instead of getting hung-up on visual design.
