Desktop app development begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross‑platform frameworks, and the distribution method. A clearly defined MVP and an early prototype help confirm 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, enterprise authentication) ensures the app remains dependable in daily use, while an update system and crash reporting support long‑term maintenance.
