What is IoT app development?

IoT app development is the process of building applications that connect to and control internet-enabled devices — sensors, wearables, smart appliances, and industrial machines — while collecting and visualizing the data those devices produce in real time.

Which technologies do you use for IoT apps?

We build with MQTT and WebSocket for real-time messaging, ESP32/Arduino for edge devices, Node.js and Python for backends, and AWS IoT / Azure IoT for cloud infrastructure. Apps are built with Flutter, React Native, or native Android/iOS.

How much does IoT app development cost in India?

IoT app development costs in India typically range from ₹4–10 lakhs for a connected MVP to ₹15–40 lakhs or more for full industrial IoT platforms. The cost depends on device count, hardware, firmware, and cloud complexity.

Can you handle both hardware and firmware?

Yes. We design end-to-end solutions covering device hardware selection, embedded firmware, cloud backends, and the mobile or web app that controls the devices.

How do you ensure IoT data security?

We use TLS/SSL encryption, secure device authentication with certificates, token-based APIs, and strict data-access policies across the device-to-cloud pipeline.

Can you integrate with existing IoT platforms?

Yes. We integrate with AWS IoT, Azure IoT Hub, Google Cloud IoT, and third-party gateways, and can migrate data from legacy systems.

How long does it take to build an IoT app?

A simple connected MVP takes 3–4 months. Full-scale industrial or smart-city solutions can take 6–12 months depending on device and cloud complexity.

Do you provide post-launch IoT support?

Yes. We provide 3–12 months of free post-launch support covering firmware updates, cloud monitoring, device fleet management, and feature additions.
