Connecting multiple frames (wireframes)embedded with UX and UI in a systematic (and controlled) manner is known as prototyping.

Here, you will bring a practical functioning life to features/ functions, etc. available in your mobile app.

This will bring a realistic approach to “how your app works?”

This is very useful to find out any mistakes to be cleared, adding new features, aligning features on the app, etc.

This will also boost your confidence level and brings a kind of small satisfaction.

To understand this effectively…

Just imagine that you are making a book that holds/contains all your work from start to finish in an orderly manner.

Now, it’s time to connect them such that they will not lose their order & looks neat.

Here, this connecting (it may be a pin, spiral binding, tied with thread) is known as prototyping.

This is how I understand prototyping.

Conclusion:-

Now, I hope you have understood about prototyping.
