This network is called the Internet of Things, or IoT. The global spending on IoT reached $726 billion in 2019, and it is expected to grow up to $1 trillion by 2022, as Statista notes. The development of IoT software is gaining momentum, and many entrepreneurs strive to explore this niche and multiply revenue.
The Internet of Things is the future that already surrounds us. So our task is to clarify each nuance concerning IoT app development for mobile and web, including its cost and steps. The process is complicated and time-consuming, so you should know everything about it.
What is the IoT Development?
For a start, you need to know more about what IoT is and how it works. IoT connects a few devices in one network that makes it possible to collect, analyze, process, and transmit data to other objects via software.
People can interact with devices, while devices communicate with each other, respond to any changes, and make decisions without human intervention. IoT devices can function independently, although people may adjust them and provide data access.
IoT systems work in real-time mode and consist of smart devices and cloud platform, they are connected to the platform via Bluetooth or Wi-Fi. For example, a smart thermometer monitors the surrounding temperature in the dwelling. If it is too low, the device sends a signal to a smart heater using relevant software, and the heater is activated. It is just one example. In fact, IoT turns your house into a smart home.
What Is Special About IoT App Development?
Custom IoT app development is entirely different from the development of any other type of application. The Internet Of Things represents a complex system that has three levels as follows:
Infrastructure. Software on a cloud server that analyzes and processes data received from connected devices.
Smart gadgets. Devices that interact with other equipment and networks. They can transmit various data to each other in an automated way while cloud software analyzes the received data.
Applications. And, finally, mobile, web, or hybrid apps installed on a user’s device allow them to control connected devices with a smartphone, tablet, or PC.
As you can see, app development is not the only thing you need for building IoT software. But we will pay more attention to it a bit later.
Challenges Of IoT
Before we speak about the development process, we think it is necessary to talk about pitfalls and challenges IoT app development bears.
IoT app development security. As IoT is a network of devices, it is crucial to ensure security and privacy. However, it is easy to say and hard to accomplish. Data security can be easily breached if one of the network links is broken. It is not always possible for developers to guarantee that the whole IoT system will function properly.
Connectivity. The next challenge is potential poor connectivity. The data is transmitted from one device to another, and if there is a poor connection or some failures, the IoT system won’t provide users with a satisfactory result. Thus, connectivity challenges are to be considered.
Compatibility. Multiple devices and sensors may be involved in the process, but they may have different standards, and not all of them will be compatible. Lack of a unified standard is a significant problem that cannot be fixed at the moment. IoT app development company must test the system to make sure that everything goes like clockwork.

Steps On How To Develop IoT Applications
What makes a successful app development result? A wise approach to the development process, of course. That is why we cannot ignore the step-by-step guide you will find below.
Choose IoT Development Platform
The platform for IoT software development is necessary since it will help connect devices to cloud solutions. There are many IoT application development platforms in the market. However, Azure IoT Suite, IBM Watson, Oracle IoT, Kaa, HomeKit are top of them. Developers will use one of the selected platforms to build a network of devices that function seamlessly.
When you are selecting a platform for IoT app development, you need to check their pricing and conditions, so that you will find the appropriate one for your project.

Choose A Hardware
Everything depends on the niche you plan to create IoT software for. For example, you may need an IoT system for home or build a system for a specific industry like healthcare, logistics, manufacturing, etc. So you need to determine what devices will become a network for your system.
Use A Reliable Data Storage
Cloud storage is necessary for the analysis and processing of transmitted data. Microsoft Azure, AWS, Google Cloud Platform — these three top cloud service providers form the basis for reliable data storage. Of course, you can choose other providers, but it is highly recommended to cooperate with proven companies.
Hire IoT App Development Company
The company must be dependable and have an experience of IoT software development. However, that’s not the only factor to consider when you choose software developers. Make sure that you feel comfortable when you are communicating with specialists. As for Cadabra Studio, one of our primary rules is to listen to our clients and take their demands into account.
If we know that there are some development issues and they are not acceptable, we explain to clients why it cannot be implemented according to their requirements, and how it can be fixed. That is why you can choose the Cadabra Studio team — we always respect the expectations of our clients.
Elaborate On User Experience
Clear and intuitive user experience is crucial for any type of app. Still, IoT mobile app development (as well as a web app) is the process where good UX means high user’s comfort and absence of dissatisfaction. If you want to make an app competitive and eye-catching, you need to entrust the project to professionals who will create fascinating UX.
As for user experience design, entrust this process to a software development company.
Safety Comes First
Although this is the last step, it must be the first step when web or mobile app development for IoT is initiated. As we already mentioned, you should choose reliable IoT platform vendors, dependable cloud service providers, and use protected networks. Developers will apply encryption methods for secure data transmission and storage.
Besides, it is essential to comply with local government regulations. For example, if you create a healthcare-related IoT app in the United States, you need to make sure that it is HIPAA-compliant. Also, software that is created for residents of California must comply with CCPA regulations. If you want to build an app for the EU-based citizens, it should comply with the GDPR.
How Is The Cost Of IoT Implementation Formed?
To estimate IoT software pricing, it is necessary to understand how the cost is formed. IoT app development cost includes not only software creation, and there are additional expenses to learn about.
Hardware. That is what everything starts with. You need to choose devices that will be used as an IoT network. However, there is a problem that ready-made devices already have relevant software, and there is no need to build your own app.
Therefore, one of the possible solutions is to build a smart device for your specific purposes. Manufacturing of smart devices includes planning, concept development, technical specification creation, modeling, engineering, and commissioning stage. It may cost thousands of dollars, depending on the complexity of the device.
Infrastructure. You should provide an Internet connection and network infrastructure for the proper functionality of the IoT system. Then, if you still want to connect ready-made devices, it is necessary to create software that will connect these devices (i.e., serve as a middleware). Finally, cloud infrastructure like AWS or Microsoft will cost you additional funds.
Application. Application development cost depends on the number of features, the complexity of UI/UX design, the integration of additional technologies like AI, etc. We will draw the line under this issue at the end of the article.
