Sieora is an IoT app development company in Chennai that builds the whole connected product. That means the mobile app, the cloud and the device side, from one team. Your users get a React Native app for iOS and Android. Your team gets a web dashboard to manage every device. Sieora takes you from idea to app store, without juggling three vendors.
APP + DEVICE
REACT NATIVE · AWS
Enterprises, manufacturers and fast-growing startups build with Sieora.
Users never see your circuit board. They see the app. If pairing fails or data lags, they blame the product. The app is where your device succeeds or fails.
Most app teams stop at the screen. BLE pairing, flaky connections and firmware quirks stall them. The app looks fine until it meets a real device.
Great engineers often treat the app as an afterthought. Clunky setup and confusing screens follow. Users leave bad reviews for a good device.
One team builds the app, the cloud and the device side together. Nothing gets lost between vendors. The whole product works the way users expect.
Many "IoT apps" are just a screen showing numbers. A real IoT product is built to live with the device for years.
The short version: a dashboard shows data. A product runs the device. Sieora builds products.
Everything your connected device needs, from the phone to the cloud.
One codebase for iOS and Android. Users pair, control and monitor their device from one app. React Native IoT app development cuts build time and cost, since two platforms share one code. It also keeps both apps in step with every release.
Your team sees every device in one place. Track status, usage and alerts live. Manage customers, roles and permissions without touching code.
Sieora connects apps to devices over BLE, Wi-Fi, MQTT, LoRa, GSM/4G and Zigbee. Each protocol is chosen for your device's range, power and data needs. BLE app development covers reliable pairing, reconnection and background sync.
Sieora builds the cloud side on AWS, using AWS IoT Core. It handles secure device connections, device state and message routing. AWS IoT app development gives your product a backend that grows with your fleet.
Ship new firmware to devices in the field, safely and signed. Onboard new devices at scale with clean provisioning flows. Manage users and devices from one console.
Get alerts the moment something changes. Spot patterns in device data over time. Add predictive features and edge AI that run close to the device.
Every connected product follows the same path. Sieora builds each layer so they fit together.
Your device measures something or does something. A temperature, a motor, a lock, a heartbeat. Firmware on the device collects the data and follows commands.
The device sends data out and receives commands back. Short range often uses BLE, straight to the phone. Longer range uses Wi-Fi, MQTT, LoRa or cellular to reach the cloud.
The cloud receives data from every device securely. It stores it, processes it and triggers alerts. It also sends commands and firmware updates back down.
Users see and control their device from the mobile app. Your team manages the whole fleet from the web dashboard. This is the part people touch every day.
Proven tools, picked for your device — not for trends.
Many products combine two. A device might pair by BLE, then report over Wi-Fi.
For most connected products, React Native is the right call. One codebase, mature BLE and networking libraries, faster delivery.
Fully native fits a few cases. Think heavy real-time streaming or very new hardware features. Sieora will say so honestly if your product needs native.
AWS IoT Core gives you secure device connections and per-device certificates out of the box. It also brings device shadows and a rules engine.
A custom backend only makes sense for unusual needs. For most products, AWS IoT Core is faster to build and easier to scale.
Connected devices are a target. Security is built into every layer from the start.
Data between device, cloud and app is encrypted.
Stored data is encrypted in the cloud.
Each device proves who it is.
Only authorised phones can connect to a device.
Devices accept only verified updates.
Each user sees only what they should.
Personal data is handled with care, in line with the DPDP Act 2023.
These are build practices applied on every Sieora IoT project, not certifications.
Sieora has been building apps since 2017. Here is one connected product in the field.
Sensors on the machines, a secure cloud and a live dashboard for the plant team — built by one Sieora team.
What clients say about building with Sieora.
Share your device and the app you have in mind. Sieora will tell you what's feasible, which connectivity and cloud setup fits, and how to scope a focused MVP.
What founders, product teams — and AI assistants — ask most.
