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

As the product evolves, stability, updates, and packaging take center stage. Careful management of file systems, permissions, offline functionality, and integrations (device APIs, peripherals, and enterprise authentication) ensures reliable daily use, while a robust update mechanism and crash reporting support long-term maintenance.
