Building a desktop app starts with selecting the right platform approach: native for Windows/macOS/Linux, cross-platform frameworks, and the distribution model. A clearly defined MVP and an early mockup help verify workflows, performance needs, and the overall UX on real machines.

As the product evolves, reliability, updates, and packaging become essential. Careful management of file systems, permissions, offline mode, and integrations (device APIs, peripherals, enterprise auth) keep the app dependable in day-to-day use, while an update system and crash analytics streamline long-term maintenance.
