Easy install. I always have Bluetooth off unless connected to headphones, so breaking that habit will be difficult. This doesn't work unless Bluetooth is on. Anyone with privacy concerns, none here, but I hope you have turned of GPS location tracking. I'm not sure those people who are concerned about privacy are even aware their location data is being tracked and stored. See Google Maps TimeLine, which I use. Personally I would favor a more aggressive contact tracing app for the case of Corona.

I had this app deleted after it finding out it wasn't working properly since Sept last year, meaning you wouldn't get notifications even if you came into contact with someone. Even now, you won't get notifications unless you open the app daily. This is an unbelievable waste of taxpayers money and I really hope someone is held accountable for this massive failure.

Works very well, took a second to install, didn't ask for any info, just gets on with it. Note that you only get anything out of it if it detects that you were close to someone who had the virus for at least 15 minutes. As hardly anyone has it in Japan, you likely won't get many hits, maybe none, at the moment at least (Essentially because preemptive efforts like this are working).
