IoT Companion Apps

We design and build secure, scalable iOS and Android apps that pair seamlessly with your physical hardware. Whether you’re launching a new consumer device, building enterprise-grade tooling, or modernizing industrial equipment with real-time visibility and control, we help you turn standalone hardware into a connected experience users love.

IoT apps don’t just connect to devices, they shape how customers perceive your product, your brand, and your reliability. We design and develop companion apps that feel intuitive from the first pairing to the thousandth use, grounded in real-world conditions and edge cases.

Who We Work With

• Consumer hardware companies creating mobile interfaces for smart devices, sensors, or connected home products
• Healthcare and MedTech teams building secure, HIPAA-compliant apps for monitoring or controlling medical hardware
• Industrial and field operations teams bringing connectivity to specialized equipment, logistics tools, or manufacturing systems
• IoT platforms and product teams who need real-time diagnostics, firmware management, or alerting built into a seamless UX
• Startups and growth-stage companies launching connected devices and needing an experienced software partner aligned to hardware constraints

If your product ships with a physical device but depends on mobile software for adoption, engagement, support or control, we’re here to help.

Approach We Take

We bridge the worlds of hardware, mobile, and cloud with user-centered design and engineering discipline.

Our approach includes:

• Hardware-Aware Planning — We align with your firmware, connectivity, and manufacturing roadmap to define what’s possible and what’s next
• Connectivity-Ready UX Design — We create interfaces that gracefully handle latency, disconnections, pairing flows, and environmental variables
• Secure Cloud & App Architecture — We design secure authentication, data flow, and command patterns for BLE, WiFi, RFID, and other protocols
• Mobile Development at Scale — We build fast, reliable native apps with React Native or native stacks, depending on complexity and performance needs
• Ongoing Testing and Real-World QA — We test against actual hardware, validate in failure states, and support firmware and backend evolution post-launch
• Dedicated QA for IoT via CarbonQA — Our CarbonQA service team specializes in QA for hardware-software systems, running embedded feature testing, bug tracking, connectivity edge-case validation, and accessibility audits to ensure every release performs in real-world environments

Our team knows how to work alongside electrical engineers, firmware developers, and field support — because seamless connectivity isn’t just a tech problem, it’s a product experience.

How It Works

Discovery & Technical Alignment

We map out your device capabilities, system constraints, and customer goals across hardware, firmware, and backend layers.

Experience & Interface Design

We design intuitive flows for onboarding, configuration, diagnostics, and data visualization — built for real usage and edge cases.

Mobile & Backend Development

We develop cross-platform mobile apps, integrate with your APIs, and support cloud architecture needs for logging, messaging, and device sync.

Hardware Integration & Testing

We test against real hardware, simulate connectivity failures, and ensure your app performs in the field, not just the lab, with CarbonQA embedded throughout.

Launch & Lifecycle Support

We guide you through app store submission, OTA updates, release management, and long-term support to keep the product evolving post-launch.

What to Expect Working With Us

You’ll get:

• Production-ready iOS and Android companion apps tailored to your hardware for clinical, administrative, support, or end-user engagement
• A user experience that simplifies configuration, builds confidence, and reduces support requests
• Secure, scalable architecture across mobile, firmware, and cloud services
• Reliability validated by a dedicated CarbonQA team trained in hardware-software systems
• A long-term partner who understands that your product is only as good as its connected experience

We help you deliver not just a device, but an ecosystem users trust, understand, and rely on daily. Let’s build it together.
