what's your opinion on COVID-19 Contact Tracing App

Hello to all of you!
hope you all safe and doing well!
after you read this short post, I would like to hear your point of few about this newly app:
This smartphone app, will be introduced on the 28th of April, by the Federal government to the Australians, and will be a close model of a similar one that's used by the Singaporean Government, (but I personally I heard that many other country will implement such similar app.
For the time been we know that this tracing app will be voluntary and will digitize the current contact tracing process that already occurs when an individual tests positive to corona virus, and that unless 40% of the population has to download this app for this technology to succeed
This app will give the health authorities a full picture of an infected person and the persons that he did personally interact with.
Before hitting the download, we need to know who will use the data?
as also this app uses Bluetooth to trace other nearby phone that have installed the app
and they guaranty that will not trace their location........but the authority can get the Id codes for all the close contacts you've had, and will use the data to contact/notify potential contacts.
So they could assess and make the decision to Isolate and test those contacts,
(they could even come to your door and carry you away) let's hope is not the case.
Observation:
Bluetooth signals travel true walls, linking you to your neighbor and so on, even if you've never actually been in actual physical contact, so it could give false positive e false negative when looking true the data! and eventually will be used to make decisions
that will effect the freedom voluntarily or not of the citizen's!
(it's a worry) as we already have lost the below
Please I really will like to hear your opinion on this new app, as myself I'm a bit concerned and puzzled about it.
I thank you beforehand for your input and participation
Take care, be safe and be well!

Most of my friends here in town don't want to register as they feel it is an invasion of privacy. But I have nothing to hide. Thanks for this discussion. cheers Jen
This app does NOTHING to prevent infection. Therefore, as far as I am concern as a consumer, it is useless to me.
If you are positive and hang around others with the app. The Gov will know who is in close proximity with whom and when, therefore it makes the job of contact tracing easier.
First and foremost, if you are not tested, it will not know if you are positive. Therefore the following scenario.
1. unknown to unknown close proximity
2. known to unknown close proximity
3. known to known close proximity
Scenarios 1 - can’t do anything cause you don’t know
Scenario 2 - you can do contact tracing to isolate these people
Scenario 3 - don’t need to do anything since both already have the virus and know about it and probably treated. Maybe you can catch them if they go out in which should be mandatory tracking and not this solution.
Going through all the trouble and violating privacy and personal data protection just for the above benefit, I think there are better solutions we can think off.
Just because a technology is available on a device doesn’t mean it is the best solution and in this case. I CHOOSE NOT to use it because the effectiveness is not there.
