When designers are working on interactive prototypes, they have some great tools to help them out. Here are a few that everyone is talking about:

1. Figma:

   • About 80% of designers really like Figma because it makes working together easier.
   • You can get feedback in real-time, which speeds things up.

2. Adobe XD:

   • Around 70% of professional designers use Adobe XD.
   • It works really well with other Adobe programs, making it easy to switch between them.

3. InVision:

   • About 67% of teams choose InVision because it has cool interactive features called hotspots.
   • It makes testing designs with users much better.

4. Axure RP:

   • More than 60% of designers use Axure for more complicated designs.
   • It allows for dynamic content and has something called conditional logic, which helps change things based on user choices.

Using these tools makes user testing easier. This, in turn, can improve design effectiveness by about 25-30%.
