FAQ
App development FAQs
Do you build native and cross-platform apps?
Yes. The approach is selected around product requirements, performance, integrations, team and maintenance lifecycle rather than framework preference.
Can the project include backend and APIs?
Yes. When required, the scope can include backend services, authentication, integrations, data and endpoints that support the application.
Can you help with app-store releases?
We can prepare the application and technical release process, including build and validation requirements. Store accounts, contracts and approvals remain with the account owner.
