Our Proven Mobile App Development Process

Mobile App Development Process

  • Discovery & Strategy: We start by understanding your goals, product features, and technical architecture.
  • UX/UI Design: We develop clickable wireframes and high-fidelity mockups, iterating based on your feedback to perfect the user flow and interface.
  • Agile Development: Working in two-week sprints, we build vertical slices of features, employing strategies for faster live debugging to improve development speed and allow for continuous evaluation by your team and our QA engineers. Read about our project execution.
  • Rigorous QA & Testing: Our testers validate every feature across the entire system. We incorporate best practices for mobile app security to safeguard user data from the earliest stages of development. We manage alpha/beta testing phases to ensure a smooth product release.
  • Launch & Support: We assist with app store submission and provide ongoing support to ensure long-term success.

Technology Platforms We Support

Native Mobile Development

For maximum performance and hardware access, we develop native applications for iOS (Swift) and Android (Kotlin).

Cross-Platform Development

To optimize for cost and speed, we leverage frameworks like React Native, a tool that allows us to bridge the gap between native modules and a shared codebase, to build applications that feel native.

Progressive Web Apps (PWAs)

For device-independent solutions that skip the app store, we develop PWAs that offer a native-like experience in the browser.

Is Cardinal Peak the Right Engineering Partner for Your Mobile App?

We are an ideal partner when:

  • Your mobile app is the critical interface for a hardware device or complex backend system.
  • Performance, security, and seamless systems integration are your highest priorities.
  • You need to de-risk your project with an experienced team that understands the entire product lifecycle, from firmware to the cloud.

Key Considerations in Mobile App Development Services

How is IoT mobile app development different from a standard app?

While a great user experience is always critical, IoT mobile app development introduces far more complexity. It requires deep expertise in hardware integration, wireless protocols like Bluetooth/BLE, software interaction, and the end-to-end security between the device, the cloud, and the app. Unlike a standard app, success depends on a team that masters the entire system, which is why our end to end mobile app development approach is so critical for IoT products.

What should we look for when choosing a hardware app development company?

Look for a true engineering partner, not just an app coder. A qualified hardware app development company should have proven, in-house expertise in three key areas: the embedded software on your device, the cloud infrastructure that connects it, and the mobile application itself. Ask to see case studies that involve physical products, and ensure they have a proven process for strategic oversight and clear communication.

What does "end-to-end app development" mean for a hardware product?

For a hardware product, end to end app development means managing the entire software ecosystem to de-risk your launch. It starts with product strategy and IoT app design, moves to developing the embedded software and cloud APIs, and culminates in building the mobile application that users interact with. As an embedded IoT app development company, we manage this entire lifecycle, ensuring all components work in perfect unison for a reliable and seamless user experience.

How do you ensure the mobile app and our IoT device will work together reliably?

Reliability comes from treating the product as one cohesive system. Our value lies in rigorous end-to-end system testing, not just app testing. We have dedicated QA engineers who are experts at identifying the root cause of an issue, whether it’s in the mobile code, a cloud API call, or the device software itself. This integrated approach is essential for launching successful and reliable mobile IoT app solutions.
