Building a desktop app begins with selecting an appropriate platform approach: native across Windows/macOS/Linux, cross‑platform frameworks, and how the software will be distributed. A clearly defined MVP and an early prototype help confirm workflows, performance requirements, and the overall user experience on actual hardware.

As the product evolves, reliability, updates, and packaging take center stage. Managing file systems, permissions, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable daily use, while an update system and crash reporting ease ongoing maintenance.
