"rating": 1,
"title": "Why?",
"body": "I like the appearance change but the horizontal scrolling to select the rhythm is clunky and slow and makes it easy to press while scrolling. At least give me an option to have a list view like before or something. I think adding variations to some of these rhythms would help out a lot because only 1 visual example for each rhythm is easy to identify after like 5 cycles. Also there should be more rhythms in general. I’ve had this app for almost a year and not having simple ones like accelerated/ tachycardic idioventricular or WAP or MAT seems like easy additions. Not asking for revolutionary changes here.",

That way you can start as basic as you want and add in more for a challenge or to test your skills. It does not give an explanation, however that’s what textbooks are for🤓! Such a great way to practice. Best app all around!",

No static strips, no rationale or explanation or instruction. And to me, that's all I was looking for. For those looking for more, look elsewhere. But, that's what the classroom is for.",
