IoT has been instrumental in bringing out paradigm changes in the world of technology and app development. The Internet of things (IoT) is the network of devices such as vehicles, and home appliances that contain electronics, software, actuators, and connectivity which allows these things to connect, interact and exchange data. The best example of integration of mobile apps with IoT is in home automation systems in what we call “Smart Homes”. Here all major systems in a house like security, lighting, heating, air conditioning and even cooking devices are intelligent which means, they are programmed to receive instructions from the users in the house and behave accordingly. This is possible because all the systems are interlinked with each other to a main hub which can be controlled and manipulated via an app located on the smartphone, tablet, e-watches, tablets etc. Mobile connectivity and in-built sensors in devices strengthen the IoT ecosystem creating a new world of opportunities. 

One of the reasons why IoT is fast becoming a mainstream technology is that our mobile devices come fully-loaded with features like geo-location based technology and multiple connectivity options like WiFi, Bluetooth and NFC. These qualities in mobile devices qualify them to be at the core of the IoT ecosystem. Earlier when a guest wanted to enter a hotel room, he needed a key or an access card. With IoT-enabled Smartphones, a guest can just open the hotel’s app on his Smartphone, select the relevant options and proceed into the room as if he owns it.
