Internet of Things in App Development: Benefits & Challenges

The Internet of Things (IoT) refers to a network of connected physical devices — like sensors, appliances, or wearables — that collect and share data through the internet, often controlled via mobile apps. Learn more about the basic IoT overview. (GeeksforGeeks)

Why It Matters

Why Founders Should Care About This Term:

• Enables smart, connected experiences that set your product apart.
• Opens up new data streams to personalise and optimise services.
• Supports automation that improves user convenience and engagement.

Use This Term When...

• Building apps that interact with physical products (e.g., smart home, fitness).
• Planning hardware integrations or sensor connectivity.
• Discussing edge computing or real‑time data collection.
• Considering BLE, Wi‑Fi, or other connectivity requirements.
• Designing user flows for multi‑device interactions.

Real-World Example

In one of our projects, we developed an IoT-based mobile app that connected to indoor air quality monitors. The app allowed users to view real-time data and receive health alerts, leading to increased engagement and better indoor awareness.

Founder Insight

Founders often underestimate the complexity of syncing hardware and software. Always budget for extra testing time and firmware compatibility checks when building an IoT‑enabled app.

Key Metrics / Concepts

• Device Connectivity Rate – Percentage of devices successfully synced with the app.
• Data Latency – Delay between data generation and visibility in the app.
• Battery Efficiency – Impact of constant data transmission on battery life.
• Data Throughput – Volume of data transferred per second.
• User Engagement per Device – Interaction frequency with IoT-linked features.
