However now there is a terrible noise with the metronome I’m unable to fix, and every other user I know has the same issues. ### 2/5 — Sound *2025-05-12* Please fix the sound so it’s not scratchy. It’s sounds like a blown speaker and is very distracting and easy to get off beat with the secondary sound. It makes the app seem faulty. ### 3/5 — Fuzzy sound? *2025-04-04* Very helpful app but it’s making a fuzzy sound with each tone. I thought it was my phone. It’s the app. Why? ### 2/5 — Used to be great *2025-02-22* Used this app for years to assist with CPR and has been great. The latest update has caused a static sound with the metronome that is terrible. Please fix this soon. ### 2/5 — iOSアップデート後から？ *2025-02-02* ノイズが入るようになって使えなくなった ### 2/5 — Used to be great *2025-01-30* This app used to be great. Now it has this awful alarm buzzing sound as well as the metronome. ### 3/5 — Was a great app *2025-01-27* Was a great app, but new update has a weird buggy sound in the background. Confusing for students. Bring it back to what it use to be. ### 4/5 — Extra sound after the beep *2025-01-01* Please get rid of the extra noise after each beep. It is not needed and sounds like the app is faulty. I work in a busy system and all of our employees have it on our phones. All the FD and ambulance services follow the beeps. Mine is set to 110. It’s amazing how fast CPR is being done when compared to when you activate the metronome! But please get rid of the extra noise! ### 3/5 — Great app, but broken now *2024-12-15* This was my go to app, but now has an alternating “beep-static” for the compressions that is likely a bug that needs to be fixed. ### 4/5 — Breathing timer interval? *2024-11-11, version 1.2* Can you please add a BVM breath timer? ### 4/5 — Auditory vs Visual Que *2024-07-09* This app is beneficial, but I would love to have a visual que for the intervals vs the auditory que due to Sensory overload on these kinds of calls ### 4/5 — Easy to use *2024-01-21* Would be better if we could change the epi times to 120 seconds, and log other drugs such as amiodarone after the first three doses of epi, calcium gluconate, sodium bicarb etc. Otherwise it’s loud and easy to follow. ### 4/5 — 用不懂 *2023-10-15* 有中文吗？这个怎么用？ ### 2/5 — Não mostra o tempo *2022-03-23* De que adianta marcar medicamento e choque sendo que ele não mostra o tempo total? App ruim. ### 4/5 — 애플워치 호환 *2021-10-06* 응급실에서 근무합니다 몇년동안 사용중인데 아직도 워치버전은 안나왔네요 워치용도 나오면 더 유용할것같아요 ### 4/5 — Great App, would like more features *2021-01-25, version 1.2* I love this app when I am the recorder during a code! My only dislike is I wish it kept track of how long each person was actively doing compressions. Without a doubt, three-plus minutes in, the first one on the chest is exhausted wondering how long it’s been. ### 4/5 — overall it is a very helpful app *2020-01-22, version 1.2* we have used this app on actual code blue situations. ive been a recorder multiple times and i work at cardiac floor, this helps us keep track of next due pulse checks and epis. the only problem i have is once u press that button esp by mistake, u cant refresh it. ## Most critical reviews (10 lowest-rated) ### 1/5 — Weird sound *2026-01-23* I used to love this app but now it has a weird scratchy noise after every beat. It has become a distraction so I’ve quit using it on codes. I’ve tried updating. It has happened on two devices. Otherwise it was a great app ### 1/5 — Amateurish *2025-07-25* Every metronome chirp is followed by a burst of static. The defibrillator/rhythm check button isn’t logically named as each check doesn’t prompt a shock. Neither the rhythm check nor epinephrine counters provide an audible signal. ### 1/5 — 使い物にならない *2025-01-08* 本来のピッピッの間に、変なブザー音が入るようになって、使えなくなりました。 ### 1/5 — Barulho estranho *2024-10-09* Está fazendo um barulho estranho na contagem desde o iOS18 ### 1/5 — Evacuaste *2021-04-16* How to evaluate na application thats proposes to help in a cpr and does not show the time in a clock has sent from the heart stop? ### 1/5 — Doesn’t work - no sound at all *2018-08-23, version 1.2* Deleted this app. Doesn’t work. ### 1/5 — Annoying sound *2018-05-17* Please have sound options for the tempo. That particular beep is horrible. Can’t stand it. ### 1/5 — Please upgrade for iOS 11!!! *2017-10-22, version 1.1* Please upgrade this app so it will work with the current and future iOS. Once upgraded I will revise my review! ### 1/5 — Update to IOS 11 *2017-10-07, version 1.1* Please update your app so it can be used with iPhone update iOS 11. Thanks ### 1/5 — What appended? *2017-08-30, version 1.1* I can't get this app tempo to function. I have loaded it twice and it won't make the noise at all. The heart beats once silently and then stops. Everyone else's seems to work. ## Most praised reviews (10 highest-rated) ### 5/5 — Amazing!! *2025-10-24, version 1.2* Every EMT should have this app installed in case you need it. Just used it last night on a code. Really helped the crew.. ### 5/5 — Great app needs an update *2025-01-26, version 1.2* Use it frequently in EMS, noticed recently there is a sound distortion happening when metronome is in use. Hopefully you can fix that bug. ### 5/5 — Amazing!! *2024-08-13, version 1.2* Every EMT should have this app installed in case you need it. Just used it last night on a code. Really helped the crew.. ### 5/5 — It does the job *2024-06-08* If you’re trained in CPR, this is what you need. ### 5/5 — Excelente *2021-10-30* Prático e monitora as drogas a serem aplicadas no ontervalo de tempo ### 5/5 — Looks handy *2020-12-26, version 1.2* FirefighterEMT here. Had envisioned an app like this but have no clue how to make. I downloaded to play with and can see as someone who acts as “code commander” the usefulness of this. Reason is that times have to be kept track of during codes and for hospital staff to have . This is hard during the chaos of a code, writing multiple times and notes on a gloved hand is all you got and not easy. Having the iPhone in my hand and simply pushing the button that time stamps when epi was given, when 2 minutes had elapsed so rescuers can switch etc makes life so much easier and better for hospital staff. I’m trying to get the word out about this app. I will recommend changes to it to make it better. Thanks ### 5/5 — 업데이트 해주세요 *2020-12-26* 119대원입니다. 정말 잘 쓰고 있습니다. 워치 호환도 부탁드립니다 ### 5/5 — Some folks would like additional features but I like the simplicity. *2020-02-12* Additional features can create other issues and complexity. During a resuscitation, the focus must remain on the patient, not the app. ### 5/5 — Watch iOS *2019-02-07* Great app. Works well. Please add the watch app. I could start the watch counting quickly when starting CPR. ### 5/5 — Dr Bah Humbug *2018-11-27* I just downloaded this app because I stopped to help at a roadside trauma the other day and had to do CPR in a real life setting. One thing I realised is that even with all my medical training (I have been a doctor for nearly 15 years), in that scenario, with just so much to think about and so much adrenaline going around, time seems to dilate, so it’s hard to measure the actual per second CPR rate. This app would have been really helpful to have had at the time. I like the simplicity, and the log, and the big, easy to see buttons. The main screen isn’t too busy, which is excellent. I have 3 suggestions though: 1. Could you add a ‘check airway and c-spine’ button please. Maybe add a respiration rate metronome too (everyone always does the respiration rate too fast). Maybe it could have a different sound to make it easy to distinguish? 2. Could you add options to change the pitch and volume of the beeps? It’s easy to hear the current ones with my relatively young ears in a nice, clean clinical setting, but it would have been very hard to hear on the side of the highway with all the peak hour traffic. And for older people, high pitched sounds are sometimes harder to hear. 3. Could you add an ‘other intervention/event button that you could label later in the log. And maybe have a section in the log where you could free type other important clinical information, e.g. ambulance arrived, intubation, iv access gained etc. Thank you so much for this app! I hope I never have to use it (outside CPR training of course)! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
