iChoice: Turn Your iPhone Into a Pulse Oximeter

Meet the iChoice Pulse Oximeter: a cool gadget that turns your iPhone or other iOS devices into a pulse oximeter. All you have to do is attach it to your device to start getting data on your blood oxygen percentage, heart rate, and pulse strength. Data is stored on your phone but can be exported in TXT or CSV formats.

The iChoice Pulse Oximeter is compatible with 30-pin devices but you can use an Apple Lightning converter to use it with newer iOS devices. Let’s not forget that this device is not intended for medical use. Sets you back $149 at the time of this writing.
