Frequently Asked Questions

Find answers to common questions about cross-platform app development and how our process works. If there are other queries, we are happy to provide more information.

What is cross-platform app development?

Cross-platform app development is an approach where a single codebase is used to create apps for multiple platforms (like Android and iOS). In other words, developers write one set of code and deploy it across different operating systems.

Is cross-platform development better than native development?

It depends on the project. Cross-platform development is great for faster development and having one app for all platforms, especially when businesses need to reach both Android and iOS users quickly. Native development might be preferable if an app requires platform-specific features or the absolute maximum performance. Many businesses choose cross-platform to save time and cost while still getting near-native performance for most use cases.

Do cross-platform apps have any performance or feature limitations?

Modern cross-platform frameworks like Flutter and React Native deliver performance very close to native apps, so in most cases users won’t notice a difference. These frameworks also provide access to a wide range of native device features. However, extremely graphics-intensive games or very niche device functions might benefit from native code or require a custom plugin. For typical business applications, cross-platform solutions are usually more than sufficient.

Which frameworks and tools do you use for cross-platform development?

We choose the tech stack based on the project needs. Our developers frequently use Flutter, React Native, Ionic/Cordova, and Xamarin. We also stay updated on new technologies like Kotlin Multiplatform and .NET MAUI. We will select the frameworks and tools that best fit your app requirements for optimal results.

How much does it cost to develop a cross-platform mobile app?

The cost can vary widely depending on the app’s complexity, features, design, and scope. Generally, building a cross-platform app is more cost-effective than developing separate native apps, thanks to the shared codebase. Our tech team will provide a detailed quote after discussing your specific project requirements. With our multiple engagement models (fixed price, hourly, dedicated team), each client can choose a cost structure that fits their budget.

How long does it take to build a cross-platform app?

It depends on complexity and features. A simple application might take around 2–3 months, whereas a more complex application could take 6+ months. Cross-platform development can speed up delivery since we develop for multiple platforms in parallel. Once we understand the project details, we can provide a more accurate timeline customized to the project needs.

Can cross-platform apps access all native device features (camera, GPS, etc.)?

Cross-platform frameworks provide libraries and plugins to access most native device features like the camera, GPS, sensors, and more. For example, Flutter and React Native have extensive plugin ecosystems for native functionalities. If a very specific capability is not available out-of-the-box, we can write a custom native module to bridge the gap. In short, your cross-platform app will be able to use almost all the same device features a native app can.

Will I own the source code and intellectual property of my app?

Absolutely. Once the project is complete and paid for, the client will own the full source code and all intellectual property rights for the app. Epistic contracts make it clear that the client retains ownership of the work product. We’re simply here to build it.

Do you provide maintenance and support after the app is launched?

We offer ongoing maintenance and support services after the app is launched. Clients can opt for a maintenance plan where we handle updates, bug fixes, performance monitoring, and adding new features as needed. Our goal is to keep the app secure, up-to-date, and running smoothly long after the initial release.

How will we communicate and track the project’s progress?

Communication is a top priority for us. We typically use email, Slack or Microsoft Teams for day-to-day communication, and hold regular update meetings (weekly or as needed) to discuss progress. Our project managers share progress reports, and clients have access to project management tools (like Jira or Trello) to monitor tasks and milestones. This way, our client is always in the loop and can provide feedback during the project.
