iAssist Bluetooth Oximeter records pulse oximeter measurements from an external Bluetooth pulse oximeter and displays the measured values.

* Pulse oximeter supports the Contec Bluetooth Wireless Fingertip Pulse Oximeter CMS-50EW
* Use 7762 pin for pairing to your phone

Instructions for bluetooth:
1) Enable your phone's Bluetooth
2) Enable your oximeter wireless/Bluetooth
3) Put your finger in oximeter
4) Tape on Magnifying glass icon and select SpO2
5) Enter 7762 pin code ( First time only )
6) Now you should get the values on your phone

The connection to phone will get disconnected due to oximeter saving energy feature after a minute.As the result, the values don't get updated.The work around this is to disable Bluetooth on your oximeter and then repeat steps 2-4 again.The app should show the disconnected message before performing steps 2-4.

Instructions for camera:
1) Put your finger on back camera
2) Wait for 5-20 seconds till the app to show the green check

Notes:
This App is developed by one person and it doesn't have the funding of major companies.The app has not been updated due to lack of time and resources.As a result it may not work with new devices.

I have a plan to update it so stay tuned for the update.
