Android development

Java has been a primary Android language since the platform launched. We maintain and extend existing Java Android apps, and build new ones in Java or Kotlin following Google's Material Design guidelines — optimized for the huge range of Android phones and tablets in use today.

Enterprise back ends

Using Spring Boot we build secure APIs that power mobile apps, connect to ERP and CRM systems and scale to handle heavy traffic. Clean architecture and thorough testing mean your system is easy to extend for years to come.

Why build with ClickEx?

• One team, end to end — strategy, UX design, development, back-end APIs, testing and store submission.
• Fixed-price phases — clear quotes per milestone, so budgets never spiral.
• Weekly test builds — install the app on your own phone and give feedback as we go.
• You own the code — full source code, documentation and store accounts in your name.
• Long-term support — OS updates, bug fixes and new features after launch.
