'COCOA log checker' that can confirm the presence or absence of contact beyond the detection condition of 'within 1 meter and 15 minutes or more' of the new coronavirus contact confirmation application 'COCOA'

The new coronavirus contact confirmation app 'COCOA ' developed by the Ministry of Health, Labor and Welfare detects contact by communicating with other terminals via Bluetooth on the smartphone, but the detection condition is 'contact within 1 meter and 15 minutes or more'. The standard is set. With the ' COCOA Log Checker ', you can check the presence or absence of contact with all contact logs with new positive registrants detected by the OS, exceeding the standard of 1 meter or less and 15 minutes or more.

Although certain standards are set for COCOA to detect contact with positive people, the log itself is recorded when there are positive people within the reach of Bluetooth radio waves. COCOA log checker is a tool that can extract the log and check 'whether the positive person was within the range of Bluetooth radio waves even for a moment'. It should be noted that just because this tool detects contact with a positive person does not necessarily mean that it is a close contact.

This tool can be used by copying the log from COCOA on iOS / Android, pasting it into the input field on the COCOA log checker page, and pressing the check button.
