Most mobile apps take between 8 and 16 weeks depending on features, integrations, and overall complexity. Larger enterprise products or highly customized solutions naturally require more time. Every mobile app development project starts with a clear roadmap, milestones, and realistic delivery timeline.

It depends on your goals. Native apps deliver maximum performance and device capabilities, while cross-platform solutions offer faster development and lower costs. As an experienced mobile app development company, we recommend the approach that best fits your users, budget, and long-term product strategy.

Pricing depends on functionality, integrations, platforms, and product complexity. Our mobile app development services are scoped around your business objectives, ensuring you invest only in the features your product actually needs instead of paying for unnecessary functionality.

Absolutely. Our app development agency handles everything under one roof from product strategy and UX research to UI design, engineering, testing, deployment, and post-launch optimization by keeping every phase aligned from start to finish.

Yes. We build native iOS and Android applications as well as cross-platform products using modern frameworks. Whether you need one platform or both, our custom Mobile app development process ensures a consistent experience across every device.

Definitely. Every custom mobile app development company should validate an idea before writing code. We conduct discovery workshops, market research, feature prioritization, and product strategy sessions to reduce risk and improve launch success.

Yes. We manage testing, optimization, compliance checks, and submission for both marketplaces. Our app development company ensures your application is launch-ready and follows current platform guidelines before release.

Yes. Launch is only the beginning. We provide monitoring, maintenance, feature enhancements, security updates, analytics, and continuous optimization to help your app grow over time as part of our ongoing mobile app development services.

Once the project is complete and contractual obligations are met, you own your application, source code, and intellectual property. That's how every professional mobile app development company should operate.

Every application is built on scalable architecture, making it easy to launch new features, support more users, and expand into new markets without rebuilding your product.

Prox combines product strategy, exceptional UX, modern engineering, and long-term growth support under one experienced team. As a trusted mobile app development company, we build digital products that are designed to launch successfully, scale confidently, and create measurable business impact.
