Desktop app development begins by selecting an appropriate platform approach: native (Windows/macOS/Linux), cross-platform frameworks, and the distribution method. 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, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline operation, and integrations (device APIs, peripherals, enterprise authentication) ensures the app stays dependable in everyday use, while an update system and crash reporting aid long-term maintenance.
