As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline functionality, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable everyday use, while an update system and crash reporting ease ongoing maintenance.
