This article explores the importance of cross-platform proficiency for developers and designers, emphasizing the creation of applications that fully leverage the capabilities of all target platforms to deliver optimal user experiences. It highlights the logistical and financial challenges of multi-platform design, urging developers to adopt the perspectives of their users, appreciating platform nuances despite personal preferences.

Key Points:

• Mastering multiple platforms is essential for developers to build applications that fully utilize each platform's features, maximizing user satisfaction.
• Developing for diverse platforms presents logistical and financial hurdles, necessitating varied skill sets and investments in multiple hardware sets. However, understanding user perspectives and appreciating different platforms, regardless of personal preference, is crucial.
• Maintaining technological fluency requires hands-on experience with various devices and operating systems, gaining familiarity with typical user applications, tasks, and workflows.
• Owning the necessary hardware is just the first step; configuring it for real-world scenarios and synchronizing data across devices is equally important.
• While aiming for perfection, developers should prioritize user needs over developer convenience. Broad platform familiarity and customer focus are paramount.

Leveraging Platform Strengths:

Applications from developers unfamiliar with their target platforms often show it. Users select platforms based on factors like social trends, cost, and ecosystem, but often appreciate the platform's unique features and conveniences. While an application needn't utilize every platform feature initially, matching competitors' high standards for native-feeling experiences is essential.

Cross-Platform Fluency: A Necessity:

Multi-platform design and development are complex, demanding diverse skill sets and significant hardware investments. Developers' platform preferences can introduce bias and blind spots. True platform fluency extends beyond testing; it involves using the platform for real-world tasks and appreciating its strengths, despite personal preferences.

This article offers strategies for efficient multi-platform work. While comprehensive platform familiarity requires investment, simplifying the process increases its sustainability and fosters user-centric thinking.

Challenges and Solutions:

Maintaining digital ambidexterity is challenging (and costly). However, advancements in emulation, affordable cloud services, powerful web applications, and the popularity of iOS, Android, and Macs have made cross-platform development easier:

• Emulation Technology: Significant improvements have made cross-platform testing more accessible.
• Cloud Services: Affordable cloud solutions offer remote access to different operating systems.
• Web Applications: The rise of robust web applications reduces platform-specific dependencies.
• Market Demand: The widespread use of iOS, Android, and Macs necessitates multi-platform support from software vendors.

Technological fluency demands dedicated time with various devices and operating systems, understanding end-user applications, tasks, and workflows. The following sections detail strategies for organizing your digital life to achieve this. The goal is to integrate diverse platforms, workflows, and design languages into your applications, ensuring all customers receive optimal service.

Hardware Considerations:

The foundation for engaging with multiple platforms is the hardware to run them, or software for emulation.

• Computers: A Mac is recommended as a starting point, with options for accessing Windows through cloud services (like Amazon WorkSpaces, Microsoft Azure RemoteApp, or VMware Horizon Air), native installation via Boot Camp, or emulation using Parallels, VMware Fusion, or VirtualBox. The author prefers separate Mac and Windows PCs for optimal performance.
• Mobile Devices: The author advises buying phones outright, avoiding contracts. Managing multiple phones involves using a single phone plan with Wi-Fi for the second phone, or a shared family plan to avoid multiple phone numbers. Google Voice is suggested for managing multiple phone numbers with a single number.

Software Solutions:

Hardware is only the beginning; configuring it for real-world use and synchronizing data is crucial. Using real data across devices requires applications and services that seamlessly synchronize digital life.

• Email: Email clients are well-suited for multi-device use, with data residing on remote servers and open protocols ensuring accessibility across platforms.
• Browsers: Modern browsers like Google Chrome offer seamless synchronization of settings, bookmarks, extensions, and history, facilitating cross-platform use.
• File Synchronization: Services like Dropbox, Google Drive, and OneDrive simplify file sharing across devices. The author cautions against file conflicts, recommending closing documents on one device before switching.
• Personal Information Management (PIM): The author uses Google tools and Exchange for calendars and contacts, avoiding iCloud due to limited cross-platform accessibility. Cloud-based note-taking solutions (Evernote, OneNote, Simplenote) and dedicated password managers (LastPass, 1Password, Dashlane) are recommended for enhanced security and synchronization.

Conclusion: Balance and Prioritization:

The author's experience highlights both the benefits and challenges of multi-platform immersion. The goal is user empathy and understanding diverse perspectives. However, the pursuit of seamless cross-platform experience might lead to overlooking platform-specific details. The author advocates for broad platform familiarity while prioritizing customer needs over developer convenience. Ignoring this balance risks falling behind competitors who prioritize user experience.
