Building a desktop app 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 mock‑up help confirm workflows, performance requirements, and the overall user experience on actual devices.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable daily operation, while an update system and crash reporting streamline ongoing maintenance.
