fully customiseable to design an app , with full control.

The collaboration (check in / check out) features within Axure RP make it a more appropriate tool for small teams than applications like Balsamiq, which are effectively single user tools. Another thing that I really like about Axure RP, is being able to create reusable components that can nest. Balsamiq, another great prototyping tool that I use regularly, does not allow symbols to be nested. Axure allows me to create more advanced interactions with fewer components.

Axure RP is a super flexible tool that let's me create design deliverables that cross the spectrum from low fidelity wireframes to high fidelity interactive prototypes.
