Creating a desktop app begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross-platform frameworks, and the distribution method. A clearly defined MVP and an early prototype assist in validating workflows, performance requirements, and the overall user experience on actual hardware.

As the product evolves, reliability, updates, and packaging take center stage. Managing file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures the app remains dependable in everyday use, while an update system and crash reports streamline ongoing maintenance.
