The 13 Best Mobile UI Design Tips & Guidelines |Mobile App Design
1. Use Best Practices for Your Target Platforms
Knowing the best practices of the mobile platform or platforms you’re targeting is an essential first step before you make any design decisions. Both iOS and Android have their own set of best practices and they’re freely available online.
Once you’re familiar with these best practices, a number of design decisions will become much easier for you to make.
2. Consider the Devices You’ll Target
In this day and age, you’re not just designing one UI for your mobile app design. With the advent of tablets, and phones of all shapes and sizes, your UI design will need to adapt to many different screen resolutions (see here for a Felgo Guide on how to support multiple screen sizes & screen densities with a single source code).
Take that into consideration and you won’t fall victim to any nasty surprises when you test out your app on different devices.
3. Get the Orientation Right for Your Mobile App Design
This is a problem unique to mobile development. You should decide early on if your app will support multiple orientations or just portrait or landscape. This will help you to make better decisions when it comes to other UI factors.
If you already know how you’ll orientate your app, what devices you’ll support and what platforms you’ll target, then you’ve gotten your most basic UI decisions out of the way.
4. Be Consistent
One of the simplest things to get right when designing your user interface is consistency. A consistent UI can be understood by people all over the world, whether it’s a home button or a set of traffic lights.
If you have 3 blue home buttons in your app and 1 red home button, you’ll quickly succeed in confusing your user. For your mobile app design keep things simple; visual cues such as colors, shapes and fonts need to be consistent within your UI.
5. Design for Users, Not Yourself
Who are you making your app for? If you can imagine the type of person that will use your app, then you’ll have a much easier time designing for them. Try to find out as much as possible about your prospective users; you can never know enough about them.
Some basic questions you can ask are:
- How old are they?
- Where will they use your app?
- When will they use your app?
- Will they use it for pleasure or work?
- What kind of device will they use?
Once you’ve answered these questions, you can begin tailoring your UI to meet their needs.
6. Consider the Size of a Finger
For most people, the finger is the tool they use to interact with your app. Whether it’s the thumb or the index finger, your UI needs to be flexible enough to read their input. Make your users happy by giving them buttons they can press without a dialling wand.
7. Choose Your Words (and Fonts) Wisely
Significant parts of your UI will involve text. For this reason, it’s crucial that the wording of buttons, dialogs, etc., are informative above all else. Keep things familiar for the best results. „Home“ and „Back“ are fan favorites, there’s no need to replace them with „Start“ and „Return“.
It’s also worth noting at this point, that you’ll want to choose a font that’s easy to read and fits with the overall style of your UI. Your choice of font may be one of the defining features of your UI, so take the time to get it right.
8. Replicate What Works
You don’t need to reinvent the wheel every time you create a UI. And often times, it’s better not to.
If you see a UI design somewhere else that you think will work well for your app, find out as much about it as you can. Replicate everything you can and only innovate when necessary.
Large companies spend a lot of time and money to ensure that they’re using the most optimal UI. If you have the same goal in mind, then there’s no reason you can’t benefit from their testing as well. Especially when all you have to do is take a look at the front end of their app. Most of them rely on common UI patterns anyway.
9. Give Clear Signals
In general, your user’s navigation through your app should be quick and painless. One way to guarantee this for the mobile app design is to make sure that navigational buttons, such as the „home“ or „back“ button, contain visual clues that give users the best chance of finding what they’re looking for.
10. Use Colors Appropriately
Your app might have some kind of color scheme long before you begin designing your UI. What’s important to remember is that, this color scheme won’t be so obvious to people using your app for the first time. In Felgo Apps, it’s simple to change your color scheme by using the ThemeColors component.
So don’t over-depend on a beautiful palette to guide users through your app. Individuals with color blindness or impaired sight will be especially thankful. Accessibility should never be sacrificed to satisfy style.
11. Test As Much As Possible
The best way to improve your UI is by testing it on as many devices as possible. This gives you a chance to find flaws you hadn’t even considered and fix them before release.
You should also invest some testing time yourself. Install your app onto a device and carry it around for a week. You’ll soon notice ways to create a better UX through smarter mobile UI design.
12. Get Feedback
Even if you’re just getting feedback from family or a friend, make sure to ask them a lot of questions about how they found the UI. Were they ever confused by what should happen next? Did they always end up where they wanted? How easy was the app to use in general?
This kind of feedback can help you refine your UI design and cause a tremendous improvement in your app’s UX.
13. Create an Intuitive UI
The end result of your UI design will be an intuitive UI. Users will be able to make educated guesses about what your UI does, and get it right. If your UI isn’t at this level yet, then you still have work to do.
14. Make app easy to use
When you build your Apps with the user on mind, you need to build with ease for use. When you design with simplicity in mind you make the experience better as well your five stars ratings go up.
