Building a desktop app begins by selecting an appropriate platform approach: native across Windows/macOS/Linux, cross-platform tools, and the distribution method. A clearly scoped MVP and an early prototype help confirm workflows, performance requirements, and the overall UX on real devices.

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