Desktop app development begins by selecting an appropriate platform strategy: native (Windows/macOS/Linux), cross-platform frameworks, and the distribution approach. A clearly defined MVP and an early prototype help validate workflows, performance requirements, and the overall UX on real devices.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline operation, and integrations (device APIs, peripherals, enterprise authentication) ensures the app remains dependable in everyday use, while an update system and crash analytics streamline ongoing support.
