The free Lifesaver app teaches users how to respond to medical emergencies and was developed with The Resuscitation Council (UK).
The app teaches users the basics of how to check and recognise serious problems, how to check for breathing and how to restart breathing using CPR, mouth-to-mouth, and abdominal thrusts for a victim of choking.
There is also information on many other aspects of first aid, medical questions, emergency info and how to book a first-aid course.
Lifesaver uses interactivity with live action video and you quickly feel immersed in the emergency of the action.
The app is free to download and use, or you can access via their website:
