Cross-Platform Application Development

There is no best platform. The app can be launched using Ionic, React Native, Flutter, or even a Native platform. It depends on specific app requirements, planned integrations, availability of source code, etc.

Cross-platform code is source code that is developed using a non-native language (e.g., C#). This code is then either translated into native code or executed via a built-in runtime machine.

Usually, app maintenance costs 15% – 20% of initial cross-platform app development costs.

Maintenance service costs depend on the quality of produced source code, availability of project documentation, and amount of technical debt. Costs tend to increase when the product owner fails to update app technologies.

Unfortunately, there is no upfront answer. A specific amount depends on complexity of planned functionality and quality of the app source code. To provide a correct estimate, it is necessary to do a discovery stage.

Two options are possible depending on the project size and detailed requirements.

For a small project with clear scope, a fixed-price model is possible. The client pays 50% of project costs upfront. The rest is due after the app launch.

For mid-size and large projects with no definite scope of work, the client pays by milestones based on the scope of work done on the project.
