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. ### 2/5 — Random dude *2026-02-15, version 3.5* 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 ### 2/5 — Cant try before signing up *2025-05-30, version 3.3* 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. ### 4/5 — Availability *2023-10-27, version 1.2* Is there a reason this app is not available on android? It’s been helpful in learning rhythm recognition but unfortunately I’m unable to extend the app to others that are not on iOS. ### 4/5 — For beginner *2021-03-28, version 1.2* Simplistic way to do basic ECG reading without the confusing leads. It starts basic and you can add rhythms from a list as you go to add to your type of Ruth’s recognition. Therefore, you can add to the complexity as you get better at recognizing each rhythm. ### 4/5 — Overall good app *2020-08-26, version 1.2* I agree with other review does need more examples of each rhythm, however did improve my recognition , also like fact that is simulation of true monitor and not just still strips to interpret ### 4/5 — Not bad *2020-05-22, version 1.2* Good for practice. But it needs multiple examples of each rhythm. ### 2/5 — Great design but poor variety *2019-09-15, version 1.2* I bought this to help me learn my blocks.there is no way to choose the rhythm you want. And the variety is just not there. For the first five minutes of me using the app it only came up with six rhythms. Definitely needs work. I’m mad I purchased this !!! ### 5/5 — Great for Med school finals!! *2017-03-12, version 1.1* Worth it! ### 4/5 — Good practice *2016-11-22, version 1.1* This is helping me to learn those heart blocks! ## Most critical reviews (10 lowest-rated) ### 1/5 — Stopped Working *2025-11-02, version 3.5* IOS 26 update and app no longer works. Was a great app to it stop working ### 1/5 — Not free *2025-03-23, version 3.2* Not free ### 1/5 — Why? *2024-06-11, version 2.0.1* 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. ### 1/5 — Not right *2023-09-27, version 1.2* It tracks when you don’t even have your watch on I put watch and phone on sofa and it was still tracking wasted my money to be honest ### 1/5 — H *2020-10-06, version 1.2* Why dose it not work on the Apple Watch ### 1/5 — Repetitive *2020-08-20, version 1.2* There needs to be multiple examples for rhythms. Within 5 minutes all of the rhythms cycled. ### 1/5 — Profiteering at its finest *2020-08-12, version 1.2* It is ridiculous that you need to pay to unlock some rhythms. ### 1/5 — Rubbish *2019-02-06, version 1.2* There are 4 rhythms to identify. Everything is locked down. You’d be better off going on lifeisthefastlane than wasting time on this ### 1/5 — Attention.. *2017-01-05, version 1.1* L'application semble gratuite mais dès que vous cliquez unlock, vous êtes facturé sans préavis. C'est nul! Et inutile ### 1/5 — Don't buy *2015-11-04, version 1.1* Shows only the rhythm no explanation....waste of money ## Most praised reviews (10 highest-rated) ### 5/5 — Honestly, great study tool for getting comfortable w/ reading EKGs *2025-05-30, version 3.3* 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. ### 5/5 — Great learning app *2025-04-02, version 3.2* Really helped me understand EKGs as they happen. Loved the game mode! I could pick it up and quiz myself anytime. ### 5/5 — Great App *2023-09-28, version 1.2* Absolutely Fantastic, works great and the extra purchase is worth it too. Have you considered adding a Left Bundle Branch Block and maybe a 12 lead option? ### 5/5 — Excellent assist to rapid rhythm analysis. *2020-10-14, version 1.2* Very pleased to have found this and to recommend esp to Drs working in unsupported rural areas in Australia needing to keep up ECG skills. Drdownunder ### 5/5 — Great App for Study *2020-10-13, version 1.2* As a Paramedic student, this application is fantastic for reviewing my own knowledge of 3-Lead ECGs. I’d love to see a 12-Lead version of this app! ### 5/5 — Arrhythmia app *2020-08-02, version 1.2* Very good if you need a refresher or just taken a basic arrhythmia course. This does teach interpretations. ### 5/5 — Excellent EKG practice!!! *2020-06-03, version 1.2* Love it! ### 5/5 — Very helpful! *2020-04-03, version 1.2* As an EMT student, this app has helped me tremendously when it comes to learning the different rhythms. I definitely recommend paying the 4.99 to unlock all of them. 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! ### 5/5 — Nice review *2019-04-17, version 1.2* A good bang for your buck on arrhythmias! So far I have enjoyed it. ### 5/5 — Just what you need !!! *2017-09-23, version 1.1* As a NYC FDNY Paramedic, I can tell you that this is exactly what you need! I purchased the All Rhythms Unlock for $4.99 and it's worth it for a total review. It's dynamic testing ONLY !!! 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. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
