Frequently Asked Questions
Answers about our mobile app development services
How much does mobile app development cost?
Pex Fusion mobile app development starts from $5,000 for a basic cross-platform app, $15,000–$35,000 for a feature-rich business app, $35,000–$70,000 for a complex native app with integrations, and $70,000–$100,000+ for enterprise-grade mobile platforms.
What is the difference between native and cross-platform mobile apps?
Native apps are built specifically for iOS (Swift/Objective-C) or Android (Kotlin/Java) and deliver the best performance. Cross-platform apps are built with React Native or Flutter from one codebase and deployed to both iOS and Android — faster and more cost-effective.
Does Pex Fusion build both iOS and Android apps?
Yes. Pex Fusion builds native iOS apps (Swift), native Android apps (Kotlin), and cross-platform iOS + Android apps using React Native and Flutter.
Can Pex Fusion publish my app to the App Store and Google Play?
Yes. Pex Fusion handles App Store and Google Play submission, including app store optimization (ASO), metadata, screenshots and release management.
Does Pex Fusion provide mobile app maintenance after launch?
Yes. Pex Fusion provides ongoing mobile app maintenance including OS version updates, bug fixes, performance optimization, security patches and new feature development.
Do you serve clients in the US, Europe, Africa, Canada and the Middle East?
Yes. Pex Fusion delivers mobile app development services to clients across the United States, Canada, Europe, Africa, the Middle East and worldwide.
Can Pex Fusion work under NDAs, MSAs and formal contracts?
Yes. We operate under Master Service Agreements (MSAs), Statements of Work (SOWs), Mutual NDAs and milestone-based contracts. Every engagement includes clear scope, acceptance criteria, delivery timelines and post-launch support terms.
Who owns the app source code, designs and store accounts after delivery?
You do. Source code, design files, API documentation, store listing assets and — where you provide or create them — the App Store and Google Play developer accounts remain your organization's property. Full access is transferred to you at final milestone acceptance under the contract.
How does Pex Fusion protect my app data and user privacy?
Every engagement starts with a Mutual NDA. Mobile apps are built with encrypted transport (TLS), secure local storage, role-based access and OWASP-aligned practices. Data protection terms align with the applicable jurisdiction's regulations, including GDPR, CCPA and regional equivalents where relevant.
Do you provide post-launch support and SLAs?
Yes. Every project includes a post-launch warranty window. Optional ongoing support agreements provide agreed response times, OS-version maintenance, security patching, crash monitoring and access to our engineering team, all documented under an SLA.
