What are the appropriate prototyping tools to use for mobile app development?

Objective:

Should the teacher request to register a blog to write homework, because of mobile app development is more interested so choose this question to explore the answer.

At the beginning of the confused, a search after a basic understanding of the approximate.

Because I caishuxueqian, the wrong place please the teachers and students pointed out.

Thank you.

Body:

The so-called prototype design, the encyclopedia entry is given the following explanations:

Prototyping is the best tool for interaction designers to communicate with PD, PM, and web development engineers. The design of the block must be the product of the interaction designer in principle, the user-centric concept of interactive design will run through the entire product. Use the insight and experience of an interactive designer to directly guide the usability of the product.

My personal understanding is that in the early stages of software development, a general design of the software to be developed, or a framework that contains page modules, elements, and human-computer interaction.

The prototype design tool is easy for developers to use wireframe description of the method, for demonstration, analysis.

Or it can be said to be a "drill" before software development.

As a prototype design tool for mobile apps, you should have the following basic performance:

1. Component libraries are specifically tailored to the mobile side
2. Can be output to mobile side, easy to preview
3. Support gesture operation on the mobile side
4. Transition animations that support mobile view switching
5. Global flowchart can be generated quickly in addition, you can also have the following points: 6. Low Fidelity
7. Rich Library of components, and can view the work of other designers
8. Grid system
9. Online Collaboration & Version management
10. Can do some abnormal check above
