As an EMT myself, my crew and I use this for BLS class, and even on calls. Works perfectly.

Great for teaching and use in the field

I’m very pleased with the simplicity of this app, especially with the time it allows for analyzing the rhythm before cycling the next two minutes. I will definitely be showing this to students the next opportunity I get to assist in teaching a class

Great App!!

I’m a CPR instructor and use this app for all my classes. I also recommend this app for all my students. I recently used this on a patient and found the metronome very good to keep a good rate for compressions.
