Prototyping is an essential part of developing web and mobile apps and tools — in fact, you can’t do without it. Just as many artists do sketches before completing a piece, UI and UX designers need prototypes to eliminate costly errors down the line.
Prototypes can also help you figure out what end users or customers need early in the design process. Nobody wants to create an end product that doesn’t work for the people who need it. With a prototype, you can create a better user experience. It’s a way of sketching out your plan so you can iron out any issues and make sure everyone’s on the same page about what you’re doing.
Prototyping helps you speed up the design process, save time and money, and improve user experience. Well, ideally, anyway.
What UX Designers Hate About Prototyping Tools
It turns out some UX designers have a love/hate relationship with prototyping tools. Perry Merrity, Senior UX Designer at CBRE, says:
“Prototyping tools aren’t all that great … each one has a couple of features that others lack and claims superiority (yet none have figured out how to make a super tool).”
UX designer Ben Kopf agrees:
“There is always something lacking in every tool. For example, one app does state-based screen changes easily but doesn’t have a good enough component library, and the other has hard to use state management but a massive, well organized component library.”
“Tools that crash are the most frustrating. It can also be challenging to get sign off/hand off design concepts. Designers work with different groups of stakeholders at different stages of the product cycle, so sometimes we need to present, prototype, conduct studies or document specs. The structure of our tools need to be flexible to accommodate our changing needs.”
What to Look for in a UX/UI Prototyping Tool
So, how do you decide on the right UI prototyping tool? As Joanna Ngai suggests, it’s all to do with what you need. Sometimes you just want to stimulate ideas by wireframing how something could work, so you can identify any pitfalls early. And at other times you need to present something interactive and working to the guys who are signing your checks.
CreativeBloq suggests you choose your prototyping tool based on:
- What you need to learn from the prototype
- The skills you already have available
- The timescale
- How you plan to test your prototype
It’s also important to think about:
- How easy it will be to collaborate and share with other people involved in the project
- How easy it is to learn and use (usability for the win!)
- Whether you need low fidelity (testing ideas), medium fidelity (testing layout and main interaction) or high fidelity (testing micro-interactions, visuals, and more)
- Price — it has to suit your budget
A key part of the prototyping process is thinking about information architecture, user flow diagrams, and getting content together. You’ll want to make sure that your UI design tool works seamlessly with the tool you’re using to manage this process. Slickplan’s website planning app works well with all UX prototyping tools.
With that in mind, let’s have a look at this year’s top UI and UX prototyping tools.
Sketch is one of the most popular tools for designing websites and apps, and it does prototyping too. In fact, it’s one of the most used UI design tools around. It’s a lightweight tool with a simple interface, leaving designers free to focus on the task at hand.
Sketch lets you transition seamlessly between design screens (artboards), add animations, and create working prototypes with a couple of clicks. Plus you can easily share prototypes and get instant feedback via Sketch’s cloud interface.
Price: Sketch is $99 for a one-year license. Design teams can get a volume license, starting at $89 apiece for two devices, and decreasing as you add more team members.
2. Adobe XD
Adobe XD is a feature rich tool that offers everything from wireframing to prototyping, and allows you to test your designs, too. Whether you’re designing web or mobile apps, or want to try voice interactions, you can do it from a single interface.
