Building a desktop app begins with selecting an appropriate platform approach: native across Windows/macOS/Linux, cross‑platform frameworks, and the distribution method. A clearly defined MVP and an early prototype aid in validating workflows, performance requirements, and the overall user experience on real devices.

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