User reviews

Mostly good missing some rhythms

This app is good it covers a lot of basic rhythms but I noticed torsades, WPW, STEMI, etc is not in the rhythm library which some are common, some are not. More of those rhythms would greatly improve this app hopefully the developers read this. Because it’s missing some other common rhythms it only get a 3/5.

Random dude

Rythms were a little unrealistic to how the appear in an ecg and there werent several of the harder/important rythms
Would have been nice if there was an option to read it as a 12 lead instead of a single rythm line

Stopped Working

IOS 26 update and app no longer works. Was a great app to it stop working

Honestly, great study tool for getting comfortable w/ reading EKGs

Accurate Interventions are listed to be expected.
Game makes the whole process easy, just read the ones you get wrong(not every time tho).
Game will make variations of rhythms.

Cant try before signing up

Would really have loved to have tried this. It looks great, looks interactive and colourful.
However I downloaded to try it before signing up and paying.
Unable to comment on anything else. 4, 12lead? Posterior?, blocks? Rhythms,Variety? Who knows. I’m deleting it now. I prefer to give my money to honest type creators where I atlas know what I’m paying for rather than signing up for a trial to then have to risk than trying to cancel if it’s not what I’m looking for.
