Cross-Platform App Development

Cross-platform app development: Reach mobile users quickly with your source code. No starting from scratch. Costs less.

Let’s talk business

Cross-platform application development services

With cross-platform app development, developers allocate available resources skillfully reusing existing source code for mobile platforms.

  • Custom cross-platform app development

    Cross-platform development keeps consistency with strategic decisions. Use cross-platform development and benefit from acquired expertise and best practices.

  • MVP development

    Cross-platform mobile app development frees startups from making hard choices. No more tech preferences. As a startup, you can reach a wider audience and decrease tension between supporters of different platforms.

  • Updates and extension

    Cross-platform app updates and maintenance can be challenging. Mobile platforms’ fragmentation, inconsistent OS updates, and hardware differences present hurdles. IT Craft’s expertise and experience reduce these differences better than most companies.

  • App reengineering

    Do you have successful software but you still lose clients? Users demand stellar experience on their mobile devices. Get back on track with IT Craft developers’ expertise.

  • App testing

    App behavior might vary from platform to platform. OS specifics and hardware make a difference. Check thoroughly to ensure users enjoy the same high-level quality apps across all platforms.

  • Cross-platform developers team extension

    Does your in-house team focus mostly on desktops? Enrich your team with mobile development experts. IT Craft’s extended team helps you expand to platforms quickly.

Cases

For over 20 years, IT Craft developers have helped startups and established companies meet the needs of their end users. Read how cross-platform mobile app development made high-quality solutions possible.

Mobile Project
FieldOne

FieldOne was an enterprise-level solution for field communication that was subsequently acquired by Microsoft. It helped manage technician activities by assigning tasks, sending reports, dispatching appointments, etc.
When FieldOne product owners started cooperation with IT Craft, they looked for maintenance of their old desktop system. However, they realized the system’s user base was diminishing, so decided to redevelop existing desktop software into a SaaS solution.
The IT Craft development team opted for Xamarin due to intensive use of Microsoft technologies on FieldOne projects.

Mobile Project
99Coaches

This German startup helps sport coaches prepare training sessions and track progress of teams and individual players. Coaches use desktops to choose exercises from a large library or prepare their own. The 99Coaches app synchronizes data with the smartphone to ensure high performance in offline mode when stable Internet connection is not available.
The cross-platform development approach made it possible to add new features to all platforms and resolve issues in less time. No need to distribute new deploys via app stores and lose time on reviews. Also, support of old devices is easier.

Industries

Cross-platform apps make it possible to adapt existing code base to market needs. Quickly.

  • Healthcare

    Apps for clinic administration, patients, and staff management are integrated into one system helping manage data seamlessly.

  • AR apps

    Mobile AR apps are made using cross-platform development tools plus native frameworks ARCore and ARKit.

  • Business process automation

    Cross-platform mobile app development means you can build mobile apps on source code you already have and know.

Phone
  • On-demand economy

    Idea validation is faster with a cross-platform app because basic functionality of Uber-like apps is not platform specific.

  • eCommerce

    Cross-platform technologies help expand a company’s presence by letting brands manage their apps using the same, well-known tools.

  • eLearning

    Cross-platform elearning apps can enrich existing learning platforms and increase their visibility among mobile users.

Technologies

Cross-platforms apps are developed with help of a non-native language (JavaScript, C#) and an intermediate framework. Source code is then compiled into native code and adjusted, if needed. The same team that works on your Web app or SaaS solution can work on cross-platform mobile development.
The following technologies foster cross-platform apps.
Yes, we have mastered and used them all.

  • React logo React Native
  • Flutter logo Flutter
  • Xamarin logo Xamarin
  • Unity logo Unity
  • Cordova logo Cordova
  • Ionic logo Ionic

    This mobile framework is based on the “write once, run everywhere” principle. Developers benefit from plugins that help them reach native device features such as GPS, camera, Bluetooth, etc. Also, Ionic is compatible with all major front-end frameworks such as Angular, React, and Vue.

Cross-platform app development process

We can help you with your app idea even if it hasn’t yet coalesced into its final form.
This is possible within a five-step approach:

  • Project discovery
  • App development
  • App launch
  • Post-launch guarantee
  • App support and maintenance

We help you:

  • Turn your business requirements into tech specifications
  • Determine realistic timeline, costs, and project risks
  • Set up priorities
  • Wireframe the best user path
  • Prepare detailed project roadmap

As a product owner, you get:

  • Well-commented app source code
  • App published in app stores or deployed on an internal server
  • Detailed project documentation
  • 1- to 3-month guarantee period for developed source code

FAQs

  • 1 What is the best platform to build an app?

    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.

    Looking for an answer for your project? Call us for a tech consultation.

  • 2 What is cross-platform code?

    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.

  • 3 How much does app maintenance cost?

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

    Development costs depend on 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.

  • 4 How much does app expansion cost me?

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

  • 5 How do you charge for cross-platform app development?

    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.
