Can make it work sometimes, but not reliably enough for clinical practice. On the plus side looks like there is android version too. ### 2/5 — Can’t wait for the app to get more accurate! *2020-02-26* I’ll give it 2 stars because I think it’s an amazing idea and can’t wait for an app like this to exist. I was hoping they could include a description of the expected response to magnet application for these pacemakers/ICDs. I was so excited about the whole thing, that I started pulling up images online to see how good it would be at detecting the devices. It got the first few right, but then most of them were wrong, unfortunately. I love the idea, but would strongly advise not using it to substitute clinical judgement! Cheers! ### 3/5 — Stopped working *2019-12-09, version 3.7* The app worked well a few months ago (the results did vary somewhat with the chest X-ray), but it’s completely stopped working. ### 2/5 — Didn’t work *2019-08-27, version 3.7* I tried multiple times on the same patient and it gave me four different responses. ## Most critical reviews (10 lowest-rated) ### 1/5 — Health provider review *2025-06-07, version 3.7* I needed this app and had the suggestion from a colleague - he had a pacemaker and the app worked. The first time I used it on a patient of mine it didn’t work. ### 1/5 — Was excellent- now worthless *2025-01-07, version 3.7* I used to love this app. Now it is almost always wrong. Do not waste time with it. ### 1/5 — App doesn’t work *2023-02-27* App crashes once you open it ### 1/5 — Something Wong *2022-02-09, version 3.7* Took pictures of my pacemaker all good. Took a picture of my friends defibrillator and looks exactly like mine, EXACTLY. THen accidentally took picture of my dog… WOW she has a pacemaker??? Something fishie here… ### 1/5 — Used to work *2021-06-24, version 3.7* Used to work much better than the android version. Now doesn't work at all. ### 1/5 — Totally inconsistent *2021-06-03, version 3.7* Between my iPhone and my attending’s Android, the app is giving 90+ percent confidence that the same image is two different brands of pacemaker. With multiple X-rays. Cannot recommend. ### 1/5 — Dead ass wrong!! *2020-05-30, version 3.7* I’m an ER nurse, a pt presented with a need for pacemaker interrogation but had no info at all regarding pacemaker. The pt had a CXR so I decided to try to app I’ve forever had on my phone with no use. It resulted with a 98% match and a 1% turns out it was the 1% that was a match! What a waste!!!!! ### 1/5 — Doesn’t work *2019-10-22, version 3.7* Had a st Jude pacemaker that when photographed said 99%medtronic then when I took another picture said Biotronik just from a change in picture angle. It never even got the right one on two guesses! Worthless! ### 1/5 — Was dead wrong. *2019-10-07, version 3.7* I work in industry and wanted this app to be a huge success. I tested it before recommending it. I pulled up a device patient with a recent chest X-ray. We implanted the device so we knew for a fact what the device is. The app said there was a 99% match to a competitor and a 0% match to the actual manufacturer of the device. I sincerely hope that the app is revised as this app would be a great asset in the hospital setting if it were accurate. So disappointed. ### 1/5 — WRONG *2019-08-30, version 3.7* Wrong 2 out of 2 times. On an ILR suggested 40% match on a company that is not even in the ILR market ## Most praised reviews (10 highest-rated) ### 5/5 — Pacer ID *2026-06-23, version 3.7* The 12 -15 times I used it it was 100% accurate. ### 5/5 — It works!! *2024-12-07, version 3.7* Works great!! ### 5/5 — Very handy in the device clinic *2024-06-17* The accuracy of this app is quite good. Very helpful tool when dealing with a unfamiliar device in an emergency ### 5/5 — It Works *2021-01-24, version 3.7* The device has to be very close and well focused within the square. Too close Will get it wrong and a little off or distant -will get you different answers. ### 5/5 — Excellent app *2019-11-20, version 3.7* Great app, works well with chest X-rays. ### 5/5 — This is HolyShit..!! *2019-09-12, version 3.7* I feel excited by this awesome app. MRI and X ray check is very important things for patients. Thank you! ### 5/5 — Amazing! *2019-05-11, version 3.6* This app is ingenious. Super helpful! ### 5/5 — Great app *2019-05-09, version 3.5* Works well! Being able to see other examples is a nice feature. ### 5/5 — Highly recommend *2019-03-24, version 3.0* I used this app when on call and it is super helpful! So glad someone has finally solved this problem! ### 5/5 — This is so useful! *2019-03-16, version 3.0* Love this app! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
