There are times when calling an ambulance can take too long due to factors out of their control, there are times when, considering the state of our roads and the recklessness of the drivers, a road accident victim is just stared at instead of being helped (it's called the Bystander effect), and there are times when you are alone with a person who's going into cardiac arrest and needs urgent medical care. For all these situations, there is now an app that lets you respond to the rapidly forming medical situations around you without causing you to panic, Call Ambulance app. 

With one click on your phone, you can raise an emergency that'll dispatch an ambulance to your location at the earliest. The app allows you to set your hospital preferences so that when the ambulance arrives, it arrives from your hospital or takes you to the hospital of your preference. There's also an option to become a first responder, if there's an issue nearby, an emergency, you get a notification to go help and will be trained accordingly by the company. There is even a blood donor's network within the app, registered blood donors show up on the list according to your needs and it even takes into consideration your last donation date, ensuring that the minimum period before you can donate again is passed before it lists you as a potential donor.

Founder and CEO of Call Ambulance, Umashankar Adi Kotturu, in a launch interview in 2015 stated that the need for the app came about on the realization that the 108 ambulance service struggled with locating the patients accurately in times of need, wasting precious minutes that can often be the thread between life and death. With Call Ambulance, using location services, ambulances know exactly where you are and dispatch can happen within seconds, which saves a lot of time.
