Safe Heart iOximeter Smartphone Pulse Oximeter for iPhone, iPad (1st Generation)

I have wonderful success using this device and it is every bit as good as oximeters used in hospitals. I have used the the iOximeter App with an iPhone 4, 5s, and a Samsung Galaxy S4. The app works great on all phones and all updates have worked great as well. The app is very straight forward and my wife and parents have been able to use the device on their first try, with no confusion or problems. This oximeter sets itself apart from all of the others that I have used because it records continuously for 12 hours for overnight data analysis, and because of the quality of the app that is available for free download. Since owning the device the company that makes the iOximeter has continued to improve the application, adding features to help me with my need to check my blood oxygen levels, and even adding new features that make the device more valuable like alarms and showing the highs and lows over time. I checked the manufacturers website before writing this review and they even state that they are currently working on new features to the App, which basically are free new versions of the device you already own that you get for free, pretty awesome. A key difference of the iOximeter over its competition that I did not realize at first, is that the iOximeter USES THE HEADPHONE JACK!! to connect to my iPhone. If I decide to switch phones, loan the device to a friend, or if I need to charge the phone while using the device, all of that is possible. Although I have not needed to charge my phone to use the device (seems to use very little battery power), I know that I can keep a charger plugged in to my phone while the device is being used. This really makes the ability to record for 12 hours seem viable. Others have stated how the quality of the iOximeter is hospital grade or better and I agree. I am very impressed with the quality of the construction and the materials used to make the device. The outside is sturdy and tough, but the inside part that fits on my finger is very soft and made of a grippy material that lets the device stay on my finger. The tension of the spring is also perfect, it did not bother me or my family at all when left on for long periods of time. Overall a very fun and very well made oximeter, and a great value, having features to ones $300 or more, if you are looking at these reviews to consider a purchase, I would go for it. I have not seen images of the app in progress so I will try to upload some user photos of the app.

UPDATE Feb 20, 2015 - Once again going thru settings I saw General:Accessibility:Mono Audio was set. Turned it off (no color)and it worked on iPhone 6+ IOS 8.1.3 . Also Music:Volume Limits off (by making it max).I had played with each setting separately but now it seems it needs some precise combination. I am happy I didn't toss the iOximeter last week after another round of futile tinkering. UPDATE Jan2, 2015 -- no updates, continues to work on iP5 w/ IOS 7 but my phone is failing. Does not work in iP 5s or 6+ with IOS 8.1.2 I had hoped that the Apple Health app might give them more room to maneuver, but now believe its not fixable. Since I know it works with an old iPhone & old IOS I believe they used some gap in Apples rules for developers that is now closed. So don't waste your money, they have not even tried to push any updates since I talked to them. ====== Works perfectly on an iPhone 5 with a 7.X IOS. I use a CPAP but still get some apnea (CNS, not obstructive). I always wondered how far my O2 levels fell during these episodes. I researched recording oximeter devices but they were either very expensive or required a USB hookup to a Windows computer running software of dubious provenance. This device (with audio extension cable) enabled me to record to iPhone and export the data to match up with what open-source Sleepyhead extracted from my CPAP unit. Worked perfectly. There were some bumps on the road to this. The oximeter did not function with an iPhone 5s nor a iPhone 6+ running IOS 8.1 (12B411). Seller's management and the IOS app developer conference called me promptly to discuss the problem. Very rare to get that level of attention. I am pretty confident that an update to the app will fix the problem. I do have a remaining question, the superb IU displays breaths per minute but scouring the internet I cannot find out how that is determined from heart beats per minute and O2 levels. However they deduce it, it would be nice to have in the export data as a further cross check of the CPAP unit's reporting.

Great machine. app needs improvement. Hard to get your data after the first night's session as you must scroll all the way from the start of session one, in tiny increments, which is maddening. I've been informed (by the company) that the memory clears after 24hrs but this is not stated in the manual or help info, that I can find, so I missed it. The work-around I used is to email the data summary after a nights recording, trash the app itself, then reload it before the next session, which clears the memory. The company itself is extraordinarily responsive though and eager to improve the functionality, so I expect new updates will fix this issue, and improve others, like faster 'leap' scrolling, a 'jump to event' function etc., maybe a calendar search, and even the ability to open or save data in other apps. So I would get it, work with it, and give them time. In every other respect it's a sleek and accurate machine, like no other I can find, especially for those of us who need precise all night recording and saveable summaries. And there is a smart and gracious company behind it. When the new updates become available this will be a great oximeter system. A longer cable would be nice, so you don't roll over on your phone, and one day.. the blue tooth fairy might visit. Until then this is definitely the one to beat.

Having spent many hours of my life asking colleagues and fumbling around for a pulse oximeter( often when I really needed one badly) I decided to buy one for myself. With most Ive looked at costing at least double this I did have my reservations as to whether it would actually work. Found it does work, pretty straighforward to use,fairly sturdy and comes in its own little carry case. Good addition to any healthcare worker's visiting bag or equipment bag.

Handy product to use for peace of mind, especially after having a lung problem it's. Ice to just check the oxygen level. Reliable and battery lasts ages.

Useful but have had problems with it being slow to pick up and display Pulse rate when exercising. It does recommend using it when still but I bought it to do spot pulse checks in an exercise class. More expensive models used in the past out perform this in the exercsie situation

Good value

Takes a while to settle down to a reading but seems accurate enough and well made. Unless your mum reads it upside down!!! Good enough value.
