The UK government takes a default position of no native mobile apps unless certain conditions are met. Native apps are expensive to develop and maintain across different platforms. Web apps that are responsive to different devices are preferred. Exceptions to the no-apps policy may be considered if a responsive web service is already in place, the content is available via APIs/open data, and there is clear evidence that a native app is necessary and justified to meet a specific user need not addressed by existing options. A approval process involves evaluating the need, alternatives, demand evidence, and justification for the chosen platform.
