How to Build an iPhone App that Doesn't Suck

Transcript

Stanford University all right why don't we get started all right so afternoon everyone uh my name is Steve marman um I amum I I was invited here today to talk about uh the iPhone user interface guidelines and I'm going to talk about that but in a broader context in in sort of the larger process of how you actually make an iPhone application that do...

Summary

In this video, Steve Marmam discusses the process of designing an iPhone application. He emphasizes the importance of considering the broader context and user needs, rather than just focusing on the technical details. He shares insights from his experience working at Apple and the Design School. Throughout the video, he provides valuable tips and recommendations for creating a successful app.

Questions & Answers

Q: What are some issues with the iPhone user interface guidelines (HIG)?

The HIG is a useful resource for referencing specific controls and positioning on the screen. However, it can be too focused on low-level details and lacks guidance on the overall app development process. It's important to think beyond the HIG and consider the broader context and user needs.

Q: How should you decide what app to build?

Instead of starting with a solution, it's important to first identify the specific user group and problem you want to solve. For example, if you want to build a social network for grandmothers, talk to them and understand their needs. Building an app for a specific user group increases the chances of success.

Q: What is the best way to ensure a successful app?

Building an app for yourself, where you are the target user, is the best path to success. This allows you to understand your own needs, what features you want, and the immediate feedback loop as you develop the app. However, if you want to build for a different user group, it's crucial to connect with them and understand their needs through interviews and observations.

Q: How can you leverage existing apps and designs?

Looking at the App Store and using existing apps as references can provide valuable insights. Consider what popular apps are doing and how users interact with them. This helps you understand user expectations and avoid reinventing the wheel. You can also find design inspiration and learn from successful apps in your target market.

Q: How should you approach exploring solutions for your app?

It's important to be mindful of the constraints of the iPhone, such as screen size, limited input capabilities, and short user interaction times. Think about what data is necessary and prioritize the essential features. Avoid overloading the app with unnecessary features, but ensure it still meets the needs of the target user group. Be minimal in your design approach and strive to achieve the right balance of features.

Q: What is the benefit of sketching and paper prototyping?

Sketching and paper prototyping offer a quick and low-cost way to explore design ideas and test user interactions before investing time in coding. Sketching multiple versions of your app allows you to iterate and narrow down the best design. Paper prototypes enable users to interact with the app's interface and provide valuable feedback. Through this process, you can discover and address usability issues early on.

Q: What tools can be used for designing iPhone apps?

Applications like OmniGraffle are recommended for designing iPhone apps. These tools provide stencil libraries and vector-based design capabilities. OmniGraffle allows you to create precise and pixel-perfect designs that closely resemble the final app. It is especially useful for collaboration and sharing design files with other team members.

Q: Why is it important to be pixel perfect in the design phase?

Being pixel perfect in the design phase ensures that the layout, spacing, and visual elements are accurate and realistic. It allows you to see how the app will look and function before starting the development process. Pixel-perfect designs also facilitate effective communication and alignment among team members, reducing confusion and interpretation issues.

Q: How can you ensure the success of your app throughout the design process?

The key is to iterate and gather feedback at each stage of the design process. Engage with actual users or target user groups to test prototypes and gain valuable insights. Embrace failure early on to identify and address flaws and usability issues sooner rather than later. This approach increases the chances of creating a successful app that meets user needs and expectations.

Q: How does exploring different design possibilities help in the app development process?

Exploring different design possibilities allows for innovation and creativity. By considering various options, you can identify unique features or design elements that set your app apart from competitors. It also gives you a better understanding of what works best for the target user group, ultimately leading to a more refined and user-friendly app.

Q: How can storytelling assist in designing an app?

Creating a narrative or persona of the target user can guide the design process. This persona represents the user's characteristics, needs, and goals. By referencing this persona during the design process, you can ensure that the app's features and functionality align with the user's expectations. Storytelling helps maintain a user-centered focus throughout the app development journey.

Takeaways

Creating a successful iPhone application involves more than following the user interface guidelines. It requires considering the broader context, understanding user needs, exploring design possibilities, and gathering feedback at each stage of the process. By being mindful of constraints and leveraging existing designs, developers can create user-friendly applications that meet specific user needs. The key is to iterate and gather feedback early on to identify and address issues before investing significant time and resources in coding. Implementing a user-centered approach and being open to failure are crucial for building impactful and successful iPhone apps.
