CBC:

A Heart and Stroke Foundation survey found 86 per cent of Canadians said they would do CPR if the need arose, but only 30 per cent of cardiac arrest sufferers actually receive bystander CPR. Parker said this is often because people feel reluctant to perform CPR due to lack of training and knowledge or fear of making the situation worse.

The app is an attempt to close that gap by providing users with at least a rudimentary knowledge of the technique, as well as the all-important reminder to call 911.

This is one of those apps that you won’t need or use every day but you can download, go over, try the exercises and hope you never have to use them. It does not replace an accredited CPR program which, if one is available to you, you should definitely take.
