If you’re an app developer, a UI kit, or App UI kit, can be your best friend. We found 20 free UI kits, for desktop, Andriod and iOS, that will save you a ton of work and free up your time for more important tasks.

The user interface, or UI, is one of the most important components of your app. It’s the primary point of interaction between users and the app, and a good UI design can be the difference between an app’s success and failure. 

But getting the UI right can be a time-consuming task, riddled with details and elements that must be consistent. Luckily, there is a solution to make UI development much, much easier: UI Kits.

In this article, we’ll answer some common questions about UI kits and how they can help you. More importantly, we’ll guide you in selecting the right UI kit for your needs.

What is a UI kit?

A UI kit is a collection of pre-made user interface elements and screens that designers use to quickly mock up their new apps or products. UI kits save product teams a heck ton of time because they don’t need to wait for designers to create unique UI elements over and over again. It doesn’t make sense holding up development and spending resources designing elements that may not make it into the final version. This way, teams can create UI mockups quickly, find the perfect layout, and then get to work creating the custom elements they’ll actually need.

UI kits come in all shapes and sizes. Some are highly general, with UI elements and screens designed for desktop, mobile, and tablet, while others are specialized, targeting a single platform or even a specific purpose.

Luckily, you can find a ton of free and paid UI kits all over the web. Developers just have to find the right one for their use case so they can make highly relevant UI mockups lickety-split.

Is it okay to use UI kits and templates?

UI kits are a great tool for app developers to quickly and easily create modern, intuitive, and good-looking user interfaces. They’re often designed to be compatible with a variety of platforms, making them a great choice for developers who are looking to create apps for multiple platforms. 

Some app developers may prefer to create a UI from scratch, so it’s tailored to their specific needs. But even in those cases, UI kits and templates can be useful. They’re great for prototyping and as a starting point for creating custom elements.

Ultimately, it’s up to you, if you use them or not, but UI kits can be a huge time-saver and headache-reducer.

UI kit FAQs

What is a UI mockup?

A UI mockup is a visual draft of your finished app or product. It allows you to plan out and revise the visual elements of your product, like the colors, fonts, and overall layout of your different screens.

UI mockups give product managers and other team leads a chance to spot design flaws that might not be obvious in the earlier stages of development. By spotting these mistakes early, teams can avoid costly delays later on in the development process and create a better overall final product.

How do you make a UI mockup?

You can create a UI mockup using any number of online prototyping tools. Using these tools, you can bring your concept sketches to life digitally using free downloadable UI elements (like those found in this article).

With the basic UI mockup done, you can get feedback from the different members of your team and refine your product until you’ve perfected its UI.
