FAQ

Mobile apps questions

Should I build native or cross-platform?
For most products, cross-platform (React Native or Flutter) gives you iOS and Android from one codebase at a lower cost with a native feel. We recommend fully native only for heavy graphics, AR or deep OS integration.
How much does a mobile app cost?
It depends on features, integrations and platforms. After a free 30-minute call we send a fixed-price proposal broken down by feature within 24 hours.
Do you publish the app to the App Store and Play Store?
Yes. We prepare store listings, screenshots, privacy forms and builds, handle review feedback and publish under your own developer accounts.
Can the app work offline?
Yes. We design offline-first data storage and background sync for field, healthcare and logistics apps where connectivity is unreliable.
