Beginning with the right platform approach is essential: native options (Windows/macOS/Linux), cross-platform tools, and how you’ll distribute the app. A clearly defined MVP and an initial prototype help verify workflows, performance requirements, and the overall UX on real devices.

As the product evolves, stability, updates, and packaging become priorities. Attentive management of file systems, permissions, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures reliability in everyday use, while a robust update system and crash reporting ease long-term maintenance.
