Clear Answers

Critical questions about scope, costs, and ownership.

What factors actually determine the cost and timeline of a mobile app?

Mobile costs are driven by three main factors: 1) Integration complexity (custom payments, real-time geolocation, or offline database synchronization require substantially more testing than static display); 2) System surface area (building an iOS app, an Android app, and a companion web admin dashboard involves multiple codebases and permission models); 3) Design readiness (teams with validated wireframes move directly to implementation; teams starting with raw concepts require discovery and prototyping first).

Should I build my app with React Native or Flutter?

Both are proven, production-grade frameworks that compile to high-performance iOS and Android applications. Choose React Native if your team has existing TypeScript/React expertise, if you want to share business logic with a React web application, or if you require direct integration with native iOS/Android system components. Choose Flutter if your product requires pixel-identical custom interfaces across all devices, complex canvas animations, or a highly self-contained UI that does not rely on native OS widgets. We evaluate both during the App Blueprint phase to recommend the right fit.

Who owns the code and design files after the project is complete?

You do. Upon final payment settlement, FFNA transfers complete 100% intellectual property ownership of all Git repositories, Figma design assets, database schemas, and documentation. We never hold client assets hostage.

Do you guarantee that our app will be approved by Apple and Google?

We guarantee that our code and assets adhere strictly to Apple’s Human Interface Guidelines, App Store Review Guidelines, and Google Play Developer Policies. If the store review team requests technical changes within the agreed scope, we resolve them during our 30-day warranty. However, no agency can legally guarantee store approval, as Apple and Google reserve unilateral discretion over business models and editorial content.

What happens if a bug is discovered after launch?

Every Mobile MVP Launch includes a 30-day defect warranty. If any reproducible defect deviates from our signed acceptance criteria, we fix it at zero cost. After the warranty period, ongoing support is available through our monthly App Care maintenance tiers.

Can we continue our conversation through Fiverr if we found you there?

Yes. If you first contacted us on Fiverr, we are happy to continue the entire engagement through Fiverr’s platform in full accordance with their terms of service. You will find a direct link on our contact page.
