InVision Freehand
The most simple software on our list, InVision Freehand, is worth a try, especially if you like generating or marking up your wireframes on a whiteboard where everyone can participate and modify. Invite your team to participate in a wireframe collaboration, where you may add photos and basic forms or design the wireframe with your mouse cursor. Because it is a cloud app, several designers and stakeholders may sign in and write at the same time.
By itself, Freehand is an excellent, though simple, wireframe tool that seems to be any other whiteboard software. However, because it supports real-time synchronization with Sketch and Photoshop, your team can sketch and remark immediately on completed prototypes, making iteration design much easier. Furthermore, because it is part of the InVision suite, your collaborative drawings are saved alongside functioning prototypes and mood boards for easy reference as you progress through your design project.
Designers who wish to communicate with team members on an initial wireframe drawing and/or remark on more refined wireframes/prototypes can benefit from using Freehand.
