One of the most critical elements of IoT that is responsible for data processing and storage.


Low-energy sensors or mobile devices that can be either custom-built or bought from third-party vendors.


Responsible for two-way communication between all relevant IoT devices, IoT gateways, and other components in the IoT ecosystem and properly linking these devices with each other.


Responsible for managing all devices within an IoT system. Whether you choose to develop a mobile app or a web app, the software should be cloud-based. Additionally, users should be able to check information collected from sensors and devices via one dashboard, and APIs should be leveraged appropriately.

How to make an IoT application that users will love

At EPAM Startups & SMBs, we advise you to build a minimum viable product to verify your idea as fast as possible and improve it according to the feedback you receive from initial customers.

And when it comes to the development process itself, we’ve prepared a list of recommended steps to implement when building high-quality IoT products, ones that people will keep using again and again.

how to create IoT applications in 5 steps

Step 1: UI/UX design

An IoT app — like any other app — needs a design that’s not only good-looking but also user-friendly, as that can help your applications stand out in the broader IoT market. Experienced product designers can help ensure the user interface is set up correctly.

Before you start the IoT mobile app or web app development process, you need to know how important a good UI/UX design is — it’s what separates successful apps from those that get removed quickly. For example, disappointed people will leave bad reviews on AppStore or Google Play, and that will have a harmful effect on the number of downloads.

In your internet of things app, make sure that the user flow is logical and there are no errors like buttons leading to nowhere. For the end user, using your app should feel natural and intuitive without unnecessary guesswork or frustration.

Step 2: frontend development

One of the most popular programming languages for frontend development is JavaScript. There are many frameworks built upon JS, like Angular, React, or Vue, that boost the software development process and provide front end developers with a great programming experience. Choosing one usually depends on individual preferences, experience, or requirements of the particular project (or a combination of these factors).

Step 3: backend development

Backend development is a bit more complicated, as you need to choose more tools that must be compatible with each other. We already covered cloud platforms before, but you must also select a programming language, database management system, and DevOps tools.

If you decide to go with JavaScript to build a frontend layer, then the natural choice for backend programming would be Node.js, as it’s also built upon JavaScript.

  • Database — CrateDB, InfluxDB, MongoDB, RethinkDB, SQLite Database
  • DevOps tools — Gradie, Jenkins, Docker

Step 4: quality assurance — automated or manual testing

Before launching, test your application to discover as many bugs as possible and fix them. Do the same with vulnerabilities, as offering a secure app is essential. Also, be prepared to receive bug reports from the users and to address any identified concerns quickly.

Step 5: collect users’ feedback and improve your app accordingly

After launching your app, listen to your initial users, collect their feedback, and create a roadmap describing what fixes or new features will be implemented and when. Make this roadmap available to your users so they know you treat them seriously and that you intend to improve your app over time.

Prioritizing Data Privacy and Security in IoT Application Development

In developing IoT applications, prioritizing data privacy and security is essential. Key measures to ensure robust security include:

  • End-to-End Encryption: Safeguarding data from the device level to the cloud.
  • Regular Security Audits: Continuously assessing vulnerabilities and potential threats.
  • Compliance with Data Protection Laws: Adhering to regulations such as GDPR and CCPA.
  • Secure User Authentication: Implementing strong authentication mechanisms.
  • Data Anonymization Techniques: Protecting user identities and sensitive information.
  • Real-Time Security Monitoring: Detecting and responding to threats promptly.

These practices are crucial for building user trust and maintaining the integrity of IoT ecosystems.

How much does it cost to make an IoT app in 2024?

Before diving into the average rates for developing IoT applications, it’s essential to understand what factors determine the final price. This includes:

  • App complexity (i.e., number of features, integration of artificial intelligence or machine learning, etc.)
  • Application security level, authentication technologies, and security features
  • Number of API integrations
  • Operating system
  • Type of application (mobile or web)
  • UI/UX design complexity (i.e., how many screens need to be coded)

That said, here’s the breakdown of the cost benchmarks based on the market averages at the moment:

  • The cost of developing a small and simple IoT app starts from $80,000.
  • The cost of developing a medium, more advanced IoT app starts from $100,000.
  • The cost of developing an advanced app with multiple features starts from $150,000.
