IoT technologies have the potential to add enormous value to our lives. With its newer superior sensors, revolutionary computing, and wireless network technologies, the (Internet of Things) IoT app development could be the next borderline. IoT applications are supposed to provide communication and information to billions of everyday items.

According to Statista, by the end of 2020, the world will have over 31 billion connected devices. The benefits of this flourishing technology will soon be felt across the globe.

Many people’s expectations for the 21st century have been exceeded, especially in IoT app development. The invention of the Internet of Things(IoT) is one component of this revolution. Despite this, IoT app development services are becoming more popular, but finding a good IoT app development company can still be difficult.

In this blog, we’ll concentrate on IoT app development, budget estimation, and the future scope of mobile applications. IoT devices do not need mobile interfaces in other industries, such as agriculture and small business but they can link to the cloud directly or be managed by web apps.

What is IoT Application?

IoT apps run on IoT devices and can be adapted to almost every industry or vertical, including healthcare, industrial automation, smart homes and buildings, automotive, and wearable technology. AI and machine learning are increasingly being used in IoT app development to give devices knowledge.

IoT applications can be used in a variety of ways to assist companies in improving,  simplifying, automating, and controlling processes while also providing relevant data, operation efficiency, and even in any kind of environmental conditions which need to be tracked and managed remotely.

This results in IoT technologies will assist in the new IoT app development for new revenue sources & business models and also provide companies with the actual data they need to improve services & products.

Type of IoT Application

  • Wearables

Wearable technology is a key of IoT technologies, and it is likely one of the first industries to use IoT to its advantage. Fit Bits, heart rate sensors, and smartwatches are all over the place these days.

The Guardian glucose monitoring unit is one of the lesser-known wearables. The system was created to help people who have diabetes. It detects glucose levels in the body using a tiny electrode called a glucose sensor positioned beneath the skin and transmits the data to a monitoring system via Radio Frequency.

  • Smart Home Applications 

Smart Homes are perhaps the first thing that comes to mind when we think of IoT app development. Jarvis, Mark Zuckerberg’s AI home automation, is the best example of IoT technologies. There’s also Allen Pan’s Home Automation System, which uses a string of musical notes to control various functions in the building. 

  • Health Care

 IoT technologies have the potential to turn reactive medical systems into constructive wellness systems. Current medical research relies on tools that are deficient in vital real-world data. 

For medical review, it often uses leftover data, managed environments, and volunteers. Via research, real-time field data, and testing, the Internet of Things open doors to a sea of useful data. The IoT app development also enhances the strength, accuracy, and availability of current devices. Instead of focusing on equipment, the IoT app development company is focused on creating systems.

  • Smart Cities

Most of you, I’m sure, have heard of the word Smart City. One of the many things that make up a smart city is the theory of the integrated traffic system.

The smart city idea has the advantage of being very unique to a city. Hong Kong’s issues are distinct from those in New York. Also global problems such as limited safe drinking water, declining air quality, and urban growth manifest themselves differently in different cities. As a result, they have a different impact on each city. 

IoT may be used by the government and engineers to examine the often complex factors of city planning that are unique to each city. Water storage, waste control, and emergency situations will all benefit from the use of IoT applications.

  • Agriculture

According to statistics, the world’s population will hit nearly 10 billion by 2050. To feed such a large population, agriculture and technology must be combined to achieve the best results. In this sector, there are various options. The Smart Greenhouse is one of them.

A greenhouse farming technique boosts crop yields by regulating environmental factors. Manual handling, on the other hand, reduces productivity, wastes resources, and increases labor costs, making the operation less efficient.

A greenhouse with embedded devices is not only easier to track, but it also allows us to regulate the environment inside it.

  • Industrial Automation

This is one of the fields where both faster growth and product quality are important factors in achieving a higher Return on Investment. With IoT app development, it’s also possible to re-engineer products and their packaging for improved cost and customer experience. With solutions for all of the following domains in its arsenal, IoT can prove to be game-changing in this area.

  • Digitalization of Factory
  • Monitor Product flow 
  • Management of Inventory 
  • Safety  Security
  • Control on Quality 
  • Optimization of Packaging 
  • Logistics & Supply Chain Optimization

Future Scope of IoT App Development

IoT technology is being used by major corporations for a variety of purposes, including effective management and production process optimization.

Manufacturing processes can be efficiently monitored with the aid of IoT technology. It’s a fascinating technology with a lot of features. As a result, many young people must study and expertise in IoT app development.

Technology has advanced to the next stage, resulting in a transformative shift in 2020. All will use the internet to access their things and computers in the future. In the future of a connected world, home automation companies and other related start-ups will play a significant role. The way people interact and live in the world will change.

Because of the automation functionality, every business owner will be able to develop their business more efficiently. It will also benefit end users’ lifestyles because they will be able to enjoy a happier and more relaxed life. In a nutshell, the IoT app development (Internet of Things) has massive future potential.

Some IoT start-ups are demonstrating their technological prowess by producing home automation devices. Not only in healthcare but in all of the directions it has taken and will take in the future, IoT app development has a long way to go. Its use in the healthcare sector is not yet as common as it should be, but it will be. Rapid scaling of these technologies will occur as the sizes and prices of devices decrease.

The Internet of Things (IoT) in healthcare is poised to revolutionize resource management, process optimization, and system integration. What is now known as the Internet of Healthcare Things would almost certainly bring about the digital transformation of the healthcare sector, among others (IoHT).

Stats of IoT app Development

One of the most powerful driving forces in future application growth would be the Internet of Things (IoT). Though IoT devices are already having a significant impact on the global network’s infrastructure, this impact can only grow in the future.

Businesses will begin to place their business strategies to take advantage of the vast opportunities for growth and evolution that come bundled with IoT by considering the introductory statistics.

The IoT app development statistics which justify the rise of IoT as technology are:

  • By 2020, it is anticipated that 20.4 billion IoT devices will be in operation.
  • The entertainment industry’s IoT initiative is expected to expand by up to 54%.
  • By 2020, 98% of cars will be linked to the internet.
  • Microsoft’s Azure IoT Suite is preferred by 29% of developers for allowing connected devices.
  • In 2022, the global IoT healthcare market will be worth $158 billion dollars.
  • By 2020, the global IoT retail market is expected to reach $35.64 billion.
  • By 2022, the global IoT in the manufacturing market is expected to hit $45.3 billion.

Factors Affecting the Cost for IoT app development

The cost of a typical IoT app development is estimated in the following guide. We’ve divided IoT app development into three main categories: hardware, infrastructure, and application development, and we’ve calculated the costs accordingly.


The cost of IoT app development in a smart system accounts for more than 70% to 80% of the overall cost. The price will eventually be determined by the form and sophistication of the solution you choose to construct.

The total cost for IoT app development is influenced by many hardware design stages –

  • Analysis: The technical specification is set out based on the complete design and the overall allocated budget.
  • Electrical Modeling: Printed Circuit Board (PCB) layout schemes, internal device visualization in 3D, Schematic Circuit Design, and COGS estimates are all examples of electrical modeling.
  • Mechanical Modeling & Industrial Design:  It mainly Focuses on 3D modeling and 3D printing, concept drawings, and electrical component integration.
  • Prototyping: Creating a working model of the solution with the least amount of hardware and evaluating the business logic.
  • Hardware Testing: The popular designs are then turned into a pre-production model that uses various materials for the system case. A variety of tests are then carried out, including climatic, pre-certification, electrical protection, and user tests.


End-to-end predictive monitoring and maintenance system architecture for the complete IoT app development being built is an essential component of the infrastructure. Which is also includes tools for managing remote devices and networks. Since the IoT’s underlying goal is continuous and automatic data collection, it’s critical to factor these systems into the cost estimate.

  • Network: Until the IoT ecosystem is supported by a highly scalable network infrastructure, a high-speed link, and low latency, it would struggle to achieve its goals. Short-range wireless cellular and LPWAN solutions are primarily used to allow IoT connectivity.

As a result, if you build an IoT app out of a system of connected devices that communicate over a cellular network, you will incur additional costs.

  • Middleware: If you want to integrate ready-made 3rd-party devices into the IoT ecosystem, you’ll need middleware, which is software that acts as an interface between two or more IoT modules, linking devices that wouldn’t communicate otherwise.
  • Cloud-based infrastructure: These are the storage software and solutions that transform hundreds of gigabytes of raw data into something useful. Since cloud storage tends to add a large amount of cost to IoT app development growth, we recommend that you use PaaS solutions built by Microsoft, Amazon, or Intel for smart device networking and data analysis.


Frontend and backend software development are equally essential, as is resourcing programmers, UI designers, integration consultants, and project managers. As your IoT development company will tell you, an IoT app development can be divided into three parts Basic, Average, Complex.

A simple IoT app development could cost about USD 40,000, but a more complicated IoT app Development which includes APIs, payment gateway integrations, or some kind of third-party data sharing could cost up to USD 100,000.

Some Major factors influence your IoT app development budget:-

  • Type of App development.
  • The degree of complexity at the UI and UX level
  • The level of security 
  • The type & number of devices the app 
  • Operating Systems &  integrations
  • Location of development
  • The team size of the resources deployed

Budget Estimation for IoT App Development

The cost of IoT app development can differ depending on the complexity of the Internet of Things development, which is determined by the number of features included in the IoT app development. The application, which can be classified as a simple IoT app due to restricted system connectivity and a lack of advanced features beyond basic data link and rendering, would cost about $30,000-$40,000.

According to harbor research, Manufacturing, smart houses, smart cars, sports IoT app development, and eHealth solutions are the most costly to introduce. At the same time, they’re in high demand and will make you a lot of money in 2020. The estimated cost of IoT production is $10,000 to $50,000. for example, the Estimated costs of an IoT app for production, home automation, and smart cities are $50,000. Monitoring systems and IoT for media are the cheapest areas (up to $10,000).


The Internet of Things (IoT) is one of the most exciting inventions in modern history. It will have an effect on all of our lives and change the way we communicate with the rest of the world. If we believe that hardware refinements and communication protocols will continue to improve, the performance of IoT devices will be determined by the quality of the IoT app development, especially how serious malicious control of objects, data access, and unauthorized surveillance will become.

The IoT app development will provide benefits to the company in a variety of ways. We should expect to see some significant improvements in the field of mobile app solutions shortly, thanks to the Internet of Things. It’s safe to assume that today’s mobile platforms and IoT will merge to create more secure and efficient mobile solutions.

Before IoT app development, make sure you’ve done your homework and selected the most reliable solutions available, as well as a trustworthy and dependable IoT app development company to work with. The best app development company will provide you effective and establishing competitive IoT platform.
