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

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file access, permissions, offline functionality, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable everyday use, while an update system and crash analytics ease ongoing maintenance.
