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

Most importantly, the device works as promised, the iphone app collects the data, i was able to view the graph on the phone, but even more importantly, i was able to view it on an Excel and OpenOffice spreadsheet where i can graph it - the app made it easy for me to mail the csv file to my computer where i double clicked the attachment and opened a spreadsheet. I checked the device against two different PO2 meters and they matched.Now the not quite so good news. It takes a sample every 4 seconds. For sleep studies this reduces its effectiveness somewhat, but for activity monitoring it should be fine. It drained the battery on my iphone 5s within 4 hours, so you have to plug your phone into the wall if you want to use the device for sleep monitoring. In addition i recommend getting a headphone cable extension since the cable length is too short even for activity monitoring - i suggest you spend a little money to purchase a good extension cable that won't provide a lot of resistance since that will reduce the current to your iOximeter and increase the drain on your iphone battery. The iOximiter raised the temperature of my iphone 5s sufficiently that i had to remove the OtterBox Defender cover to protect the phone from overheating. As for the finger device itself, that was a little tight. I hope they consider a two hinge design that will be more comfortable. Even with those caveats i still recommend the device.Compare it with the Masimo MightySat Fingertip Pulse Oximete which is 4 times the price, connects through bluetooth and samples once every second.

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.

This product has a design that makes it superior to the competition. Instead of having hardware that plugs into a certain phone, the unit plugs into the headphone jack, making it easy to use it with a variety of different smartphones, while having the smartphone plugged in. This is necessary if you use the oximeter overnight as it will run down the battery.The features that I think are needed is ability to run overnight and send the file to another computer. The collected data can be emailed as a CSV file.The app itself, though, needs a few tweaks to make it run better. First, the data cannot be deleted. The only way to delete old data is to remove and reinstall. The other issue is inherent with the design. To power and communicate with the unit, it is done over the headphone jack. To do this, it turns the volume to the maximum. One needs to remember to turn down the volume if listening to music after using the oximeter. Also, and this is probably overlooked, the iPhone (at least IOS8) lets you set a maximum music volume. I thought that this might help in keeping the volume of music down, but I think it also keeps the oximeter from setting the volume to the maximum needed to power the unit. So if you have this set, I think it may not work!The two improvements to the app that would make this a five star rating would be to have a way to delete the data, and an automatic adjustment to lower the volume when the unit is not plugged in.

This, along with the downloadable iOximeter app works as a data collector for SPO2 and pulse rate. Unlike a lot of electronic equipment, it starts up an runs with little to no effort. For this alone it deserves three stars. However it does have it share of electronic headaches. The data is difficult to view on the screen, it is also difficult to correlate. The machine has setable alarms, however all they do is flash the screen, not really much of an alarm. There may be a setting I'm missing, but it will only record for about four hours, then it quits. It has a data dropout usually once or twice per recording session. It allows the data to be emailed in a .csv file, but it records so many data points, it is difficult for excel to read them all. And, then a chart has to be created and examined. That process is about a five minute (at best) exercise.Bottom line-pretty decent for what you pay but it comes across as an early effort that could be improved by a bit of error checking and quality control.

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

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.

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.

easy read, does what it says on the tin. Have had some problems with it picking up a trace.

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.
