Pulsar CPR is a simple and free application designed to assist with CPR by providing users with the recommended pace of heart compression. This app is developed by kcck and falls under the category of Lifestyle with a subcategory of Health & Fitness.

With just one click, users can start the assistant and begin the CPR process. The app demonstrates the recommended chest compression frequency through heart pulses, and a beep sound indicates when the chest compression should be performed. The chest compression counter restarts to suggest the rescue breath, and the app shows the elapsed time from the start of CPR. Additionally, users can call an ambulance with just a click of a button, which initiates the call on the speaker's phone.

The app allows for customization of pulse frequency and chest compression counter restarts, making it adaptable for both adults and children. The default configuration is set for adults with 100 pulses per minute and rescue breath every 30 pulses. The ambulance phone number is set to 112 by default but can be easily changed to a country-specific number such as 911.

Overall, Pulsar CPR is a useful and straightforward app that assists during a critical moment. It is highly recommended for those who want to be prepared in case of an emergency.
