FAQ
Mobile Apps — common questions
Do you build native or cross-platform apps?
We recommend cross-platform (e.g. React Native) when speed and budget matter; native modules when platform-specific features are critical.
Can you extend our existing web backend?
Yes—mobile apps typically share APIs with your web product for consistent data and auth.
Do you handle App Store submission?
We guide assets, builds, and review requirements; store accounts remain under your ownership.
How long does an MVP take?
Many MVPs ship in 10–16 weeks depending on feature depth and design complexity.
What about maintenance?
We offer post-launch updates for OS changes, bug fixes, and feature iterations.
