Building a desktop app begins by selecting an appropriate platform strategy: native for Windows/macOS/Linux, cross‑platform frameworks, and the distribution approach. A clearly defined MVP and an initial prototype help verify workflows, performance requirements, and the overall user experience on real devices.

As the product evolves, stability, updates, and packaging take on importance. Thoughtful management of file systems, permissions, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures reliability in everyday use, while an update system and crash reporting ease ongoing maintenance.
