Frequently Asked Questions

Everything you should know before starting the project.

React Native or Flutter – which is better for my project?

expand_more
Both frameworks are excellent. We recommend React Native if your team already knows JavaScript/TypeScript or web integration is planned. We choose Flutter for maximum performance and pixel-identical UI design. We determine the best choice together in a short discovery call.

Can the app work offline?

expand_more
Yes – offline-first is standard in many of our apps. We implement local SQLite databases (e.g. WatermelonDB or Drift) and intelligent sync logic that synchronises data in the background as soon as a connection is re-established.

How does integration with existing ERP or backend systems work?

expand_more
Via secure REST or GraphQL APIs. We develop both the app and the necessary backend endpoints. Authentication via OAuth2/JWT, encrypted transmission and GDPR-compliant data storage are a given.

How does the App Store and Google Play submission process work?

expand_more
We handle the entire deployment process: app signing, store listings with screenshots and descriptions, and the submission process with Apple and Google. We can also set up a CI/CD pipeline that automatically distributes new versions.

What does an iOS and Android app cost from HELITS?

expand_more
A cross-platform app (React Native / Flutter) for iOS and Android costs from approx. €25,000 for a focused MVP. Scanner apps or field service apps with ERP integration typically range from €40,000–€80,000. After a discovery call you receive a binding fixed-price offer.

How long does app development take until publication?

expand_more
From kickoff to App Store publication typically takes 10–16 weeks. Weeks 1–2: Discovery & UX concept. Weeks 3–10: Development in agile sprints. Weeks 11–12: Testing & store submission. The Apple review process typically takes an additional 1–3 business days.

Are the apps developed GDPR-compliant?

expand_more
Yes. All apps use encrypted data transmission (TLS 1.3), OAuth2 authentication and store personal data exclusively on servers in German or EU data centres. Consent management, data deletion concept and data processing agreement (DPA) are part of the standard deliverables.
