Building a desktop app begins with selecting an appropriate platform approach: native on Windows/macOS/Linux, cross-platform solutions, and the distribution strategy. A clearly defined MVP and an early prototype help verify workflows, performance requirements, and the overall user experience on real devices.

As the product grows, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures daily usability, while an update system and crash reporting ease long-term maintenance.
