A clearly defined MVP and an initial prototype assist in validating workflows, performance requirements, and the overall user experience on real hardware.

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