Making an IoT App in 2022: a Guide Under Which You Will Definitely Do It

Internet of Things (IoT) applications are already changing the way we function on a daily basis by relieving us from doing both simple and more complicated tasks. But that’s not all — building IoT applications is also meant to make consumers’ lives better, whether it’s the concept of a smart home or a wearable band tracking our health rate during different activities.

In short, the Internet of Things means physical devices (or groups of devices) equipped with sensors, software and other technologies, and the ability to connect and exchange data with other devices and systems via the Internet or other networks (like Wi-Fi or Bluetooth).

IoT technology has a huge impact not only on individuals but also on business and society in general. And a quick look at some stats is enough to see that impact only growing in the future. For example, according to Statista, the number of connected IoT devices will grow from 13.8 billion units in 2021 to 30.9 billion units in 2025. It indicates that there will be more demand for IoT apps and devices, and consequently, more companies that develop them. EPAM is proud to be one of those companies.

Creating an IoT application: mobile app or web app?

If you’ve already chosen a niche for which you want to build an IoT app, it’s time to decide whether it’s better to build a mobile application or a web application.

Why it’s better to build a mobile app vs web app

  1. Better discoverability, as you can add your app to AppStore or Google Store
  2. Better accessibility to the device’s features and resources (and that means greater functionality)
  3. Better security, as mobile apps must be approved before being added to the app store
  4. Mobile apps can work without an active Internet connection, i.e. via Bluetooth
  5. They are usually faster and easier to build than web apps

Why it’s better to build a web app vs mobile app

  1. Lower development costs
  2. They work straight in a browser, so it’s not necessary to download them
  3. There is no need to build two separate apps, which might be the case if you want to build a mobile app
  4. They are easier to maintain and update
  5. They don’t have to be approved by anyone, so you can launch quickly

How to make IoT applications that users rely upon  

At EPAM, we advise you to build a Minimum Viable Product (or Minimum Viable Application in this case) to verify your idea as fast as possible and improve it according to 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 them again and again.

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. Experienced designers can help ensure this aspect is taken care of properly. You can find them in a variety of ways, i.e. on Behance or by looking for app design agencies and checking their portfolios.

Before you start developing your own app, you need to know the importance of good UI/UX design – 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 bad effect on a number of downloads.

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.

Step 2: Front-end development

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

Step 3: Back-end development

Back-end 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; here, you must also choose a programming language, database management system and DevOps tool.

If you decide to go with JavaScript to build a front-end layer, then the natural choice for back-end 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. Be prepared to receive bug reports from the users and to quickly fix them as well.

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.
