Building a desktop app begins by selecting an appropriate platform approach: native across Windows/macOS/Linux, cross‑platform frameworks, and the distribution method. Defining a solid MVP and an early prototype helps confirm workflows, performance requirements, and the overall user experience on real devices.

As the product evolves, reliability, updates, and packaging take center stage. Careful management of file systems, permissions, offline operation, and integrations (device APIs, peripherals, enterprise authentication) ensures daily usability, while a robust update system and crash reporting aid long-term maintenance.
