Things you don't know your smartphone could do

USE YOUR PHONE AS A REMOTE CONTROL 

It doesn't matter which type of phone you use. You'll find some really interesting apps in the app store relevant to your phone's operating system, that can give it a remote control-like functionality.
While the number of devices you can control with this feature isn't all-encompassing, it can for example, work with some DVD players and laptops.

CHECK YOUR PULSE RATE 

The various sensors in high-end phones allow for the measurement of your heart rate, how efficiently you burn calories and how soon your heart rate recovers after exercise, which is an important indicator of cardiac health. Incidentally, there are also other apps that can help you track your calorie intake via your diet, which are worth checking out.

PREVENT DRUNK DIALING 

Having one too many and poor selfcontrol when inebriated is a bad combination, especially when it comes to drunk dialling. There are apps that block you out from dialling numbers unless you can pass a sobriety test of pre-determined questions.This includes a simple quiz and a screen graphic that tests your manu al dexterity.

MEASURE THE SPEED OF A VEHICLE OR ANY MOVING OBJECT 

You might never have thought that you can measure the speed of a moving vehicle, or even someone who is running or how fast they can bowl even, using your smartphone.
Although more of a cool gimmick to impress your friends with, the apps you have to use for this are available in both Android and iOS stores and are free.

USE YOUR PHONE AS A TAPE MEASURE 

There are apps that use the in-built accelerometer (this is the sensor that rotates the screen from vertical to horizontal orientation as you tilt your phone) to indicate to you how level a surface is. It can come in handy when you need to hang some framed pictures or photos on a wall and need to know if it's level. All you need to do is to set your phone on or against the surface of a given object. Other apps use trigonometry to measure distance, height, width, and area of a given object. All you need to do is to point your phone's camera at what you want to measure and click.
