The short answerIoT app development is building the software around connected devices: mobile apps that pair over Bluetooth or Wi-Fi, cloud platforms that ingest telemetry, dashboards and alerts, and secure update mechanisms. An IoT companion app with cloud backend commonly costs $80,000-$250,000.
Cost ranges are US planning figures, not quotes.
What is IoT app development?
IoT app development is designing and building the mobile, web and cloud software that lets people and businesses connect to, control and monitor internet-connected devices.
We build the software layer around your device and firmware team; for pure embedded firmware we work alongside your engineers.
IoT software we build
Projects we are most often asked to build.
Consumer device companion apps
Bluetooth or Wi-Fi setup, control and history for smart products.
IoT cloud platforms
Device identity, telemetry ingestion, storage and rules.
Monitoring dashboards
Real-time status, alerts and history; see dashboard development.
Fleet management
Provisioning, grouping and remote configuration of many devices.
Over-the-air updates
Secure firmware and configuration delivery.
Industrial and commercial IoT

IoT security
Connected devices are a security responsibility.
- NIST IoT cybersecurity guidance for device manufacturers (NIST).
- Unique device identities and certificates.
- Signed, verified OTA updates.
- Least-privilege cloud access and encrypted transport.
Our IoT app development process
We map device capabilities and data, choose connectivity and cloud services, build secure device identity and ingestion, develop the companion app and dashboards, test on real hardware and plan fleet operations.
How much does IoT app development cost?
As a planning range, a companion app for an existing device platform commonly costs $60,000-$130,000, an app plus cloud backend $80,000-$250,000, and industrial IoT platforms more.
| Scope | Typical range | Timeline |
|---|---|---|
| Companion app (existing cloud) | $60,000-$130,000 | 3-5 months |
| App + IoT cloud backend | $80,000-$250,000 | 4-8 months |
| Industrial IoT platform | $200,000+ | 6-12 months |
Technology we typically use
Mainstream, maintainable choices.
| Layer | Choice |
|---|---|
| Mobile | Swift/Kotlin or React Native with BLE libraries |
| Cloud | AWS IoT Core or Azure IoT Hub |
| Messaging | MQTT |
| Backend | Node.js or Python |
| Data | Time-series storage, PostgreSQL |
| Dashboards | Next.js |
Mistakes to avoid
Common causes of overruns and low adoption.
- Testing only in simulators.
- Shared credentials across devices.
- No OTA plan.
- Assuming constant connectivity.
- Ignoring battery impact.
- Storing all telemetry forever.
