Considerations for IoT App Development

The textbook definition: Internet of Things (IoT) is the network of physical devices connected to each other. In layman’s term, any device or appliance that is connected to other such items via the internet or any such wireless network.

You must have watched in movies devices like smart mirrors that show weather and news, and touch screen car dashboards. These things are not fantasies anymore but present-day gadgets.  IoT solutions aren’t just for larger than life devices but also for normal appliances. You can convert your regular water faucet or AC into an IoT Compatible device with some simple adjustments.

There are some sensors and radio frequency tags that receive commands from your mobile or computer and follow the instructions accordingly. So you can sync your mobile’s alarm with your bathroom’s faucet so that after 15 minutes it will start heating water for your bath. And the fridge can send a message to your smartphone with the list of items running low like milk or eggs.

What is the IoT App Development?

The textbook definition: IoT App Development is an amalgamation of many different skills in the production and maintenance of app products like Native/Hybrid apps, web applications built to control consumer electronics, IoT devices. Simply said, IoT app development is the means by which we develop a platform where unconventional smart home Devices  (toaster, doorbell, etc) communicate with conventional IoT devices (computer, smartphones, tablets).

If we are talking about IoT developers then, they are working to make other unprecedented objects also networking just like present-day mobile devices.

Present day IoT facts:

  • In the year 2018, there are almost 2 billion individual devices across the world connected via IoT technology.
  • It is projected that the IoT industry will become a whopping $3 trillion business by 2020.
  • Back in 2008, there were more devices connected to the Internet than people.
  • ATMs can be considered as some of the first IoT devices that went online back in 1974.
  • The market for Radio Frequency Identification (RFID) tags, used for transmitting data to identify and track objects, is worth more than $11.1 billion.

IoT (Internet of Things) examples:

Smart Home, connected devices from bulbs, fans to TV and in some cases the entire house is Smarthome.

Business offices have adopted smart projectors, voice-enabled assistants (Alexa, Home Pod, Google Home) and other devices. Transportation has real-time responsive vehicle dashboards that warn you about traffic and even save lives by projecting possible accidents and warn the driver in the span of milliseconds. A groundbreaking example of this is the BMW i8.

The possibilities are endless with IoT web development. With more and more things joining the IoT club and that too the objects that could never have been imagined to become an Internet of Thing.

Advantages of IoT app development

Data is the currency of the future. So the more data you have, the richer you are. IoT devices like smart clothes can keep track of your skin condition and warn of possible skin conditions. This information can be sent to your dermatologists who can clearly understand your symptoms without making an error and give the right cure.

Time is the most invaluable thing; more for people who may be fighting a life or death situation. If the paramedics responding to an accident call have an IoT device that can give the vitals and relevant medical information of the patient then countless lives can be saved because of the timely response.

Money is the driving force of the financial world and IoTs are saving a whole lot of it. If your fridge knows which grocery items are running low, it can send a list of items to the home assistance device which can order the groceries from the best and cheapest source.

Tracking your daily activities will give in-depth information about almost everything. This makes medical, retail, entertainment, and many other industries to cater to your needs on a more personalized level.

IoT Product Design

If you are an IoT web developer or an entrepreneur planning to build an connected products  or IoT service then you need to learn what platforms and what languages will be used for the same. The pre-requisites before starting you IoT product design (for this blog we would consider IoT app development) are:

IoT Development Platform

IoT app development programming languages were more unique earlier but now common web and app development languages can be used. This choice in programming languages freed IoT app development from restrictions that were present with older embedded systems. The choice of programming language can be done on the basis of the knowledge of your app developer, compatibility with your IoT app development ecosystem, the speed of development, size and memory of the code, and efficiency required.

Programming LanguageAdvantagesDisadvantages
C & C++Almost every programmer know this languageCode is more hardware-specific
 Popular for Linux OS and Arduino which were used for IoT software systems 
JavaCode is less hardware-specific, making it more portableRequires libraries to run on different hardware
 Write once, run anywhere type of code 
PythonIt’s an interpreted language, making it more flexible.Compared to Java’s speed, Python is slow.
 Codes are easy to write and read. 
 Perfect for data-heavy apps. 

There are many other options for programming languages like Node.JS, JavaScript, Go (Google), Rust, B#, Parasail, etc. to choose from.

Back End Development

When trying IoT app development you need to consider that each device has different capabilities and commands. The way of communicating with each device will vary. So a pre-defined framework for communication should be set or each individual device that the IoT app can understand. Node.JS has emerged as the common framework for this type of communication between IoT devices.


Design strategies for slow connections should be adopted. Unlike traditional websites, where requests go to a web server which sends data back; there is another communications step involved for IoT devices. This potentially means additional latency and the user’s perception of slow response.

User Interface (UI)

The UI for IoT app should be fast, clean, and intuitive. The need for a good feedback program and user-assistance is a must to get precise data from the IoT device. Because the app will be in the mobile device and command other non-mobile IoT devices, all the standard usability practices are to be integrated for the users’ ease.

IoT app development has a bright future
