FAQ
Common questions
Do you build native or cross-platform apps?
Both. The choice depends on device capabilities, performance needs, team constraints and the expected life of the product.
Can Underlabs build the back end too?
Yes. Mobile products often require APIs, authentication, administration, data workflows and infrastructure, which can be designed as one system.
Can you modernize an existing app?
Yes. We can assess the codebase, product experience, integrations and release risks before recommending a focused modernization path.
