      Frequently Asked Questions

      How much does a mobile app cost to build?

      The cost of developing a mobile app varies depending on its complexity, features, and platforms. Most small to midsize apps range between $20,000 and $100,000. Enterprise-level or multi-platform solutions can exceed that. At Sunlight Media, our Los Angeles app developers create transparent estimates based on scope, technology stack, and long-term scalability goals.

      How long does it take to develop a mobile app?

      Most mobile apps take between three and six months to design, build, test, and launch. Simpler MVPs may be completed sooner, while large projects with advanced integrations or backend systems take longer. Our agile Los Angeles development team works in phases to keep progress clear and predictable.

      What is your process for app development, and how long does it typically take?

      Our process includes discovery, design, development, testing, launch, and post-launch support. Each phase is managed in agile sprints with clear deliverables and review points. Timelines vary by project size, but the typical Sunlight Media app lifecycle runs about 12 to 24 weeks from concept to completion.

      What makes a mobile app successful?

      A successful mobile app solves a clear user problem, offers intuitive design, and runs flawlessly on every device. Strong UX, fast performance, and consistent updates keep users engaged. Our Los Angeles team focuses on aligning business goals with user needs to ensure measurable success after launch.

      Do mobile apps make money?

      Yesโ€”many apps generate revenue through in-app purchases, subscriptions, ads, or premium upgrades. The key is choosing the right monetization model for your audience. We help clients analyze user behavior and integrate payment options that balance profitability with great user experience.

      What types of mobile apps can you develop?

      We build native iOS and Android apps, cross-platform solutions with Flutter or React Native, and hybrid apps that blend web and mobile functionality. Our experience covers industries such as e-commerce, education, health, entertainment, and enterprise automation.

      What is UX design in mobile app?

      UX design focuses on how users interact with your appโ€”navigation, layout, and flow. A great UX minimizes friction and guides users naturally toward their goals. Sunlight Mediaโ€™s design team in Los Angeles crafts wireframes and prototypes that make every interaction smooth and intuitive.

      How do I ensure my app is accessible to all users?

      Accessibility means making your app usable by everyone, including people with disabilities. We design with contrast ratios, text scaling, voice-assist compatibility, and gesture navigation in mind. Following ADA and WCAG guidelines helps your app reach the widest audience and meet compliance standards.

      Do I need to test my mobile app before launching it?

      Absolutely. Testing ensures performance, security, and user experience meet expectations before public release. We perform functional, usability, and device compatibility tests on both iOS and Android platforms to catch issues early and deliver a polished final product.

      What is the difference between native and hybrid app development?

      Native apps are built specifically for one platformโ€”Swift for iOS or Kotlin for Androidโ€”offering the best performance and user experience. Hybrid or cross-platform apps use frameworks like Flutter or React Native to run on both systems with shared code, reducing cost and development time.

      How do you ensure the security of the app and user data?

      We use secure coding practices, data encryption, and multi-layer authentication to protect user information. Regular security audits, HTTPS protocols, and server-side validation help prevent unauthorized access and keep apps compliant with modern privacy standards.

      What kind of maintenance will my mobile app need after it's launched?

      Apps require regular updates for new OS versions, device compatibility, and security patches. Our Los Angeles maintenance team also monitors analytics, user feedback, and performance to identify opportunities for improvement and ensure long-term reliability.

      Can I update my app after it's launched?

      Yes. You can release new features, fix bugs, and enhance design elements anytime after launch. Sunlight Media provides continuous support and version updates to keep your app evolving alongside user expectations and platform changes.

      Can you help with app store submissions and post-launch support?

      Yes. We handle App Store and Google Play submissions, prepare required assets, and manage compliance with platform guidelines. After launch, our team offers ongoing analytics, updates, and technical support to maintain strong performance and user retention.

      How do I protect my app idea from being stolen?

      You can protect your app idea through non-disclosure agreements (NDAs), trademarks, and copyright for unique content. We always sign NDAs before starting development to safeguard your intellectual property and ensure full ownership of your final product.

      What is the cost structure for app development, and do you offer flexible payment options?

      Our app development pricing is milestone-based and tailored to your project scope. We typically split payments across key phasesโ€”design, development, and launch. Flexible payment schedules are available for long-term projects, ensuring affordability without compromising quality.
