I don't understand why this app was so difficult? How complex is it? Doesn't all it do is detect when another phone is nearby and send the data back somewhere? I heard it's draining on power, because blue tooth has to be on all the time. I also heard it's iphones they can't get it to work on, which does not surprise me. Apple are very much more controlling of the software that runs on their products.
It's not but the government made it so. Don't fall for the government blame Apple line everyone told them it would not work. It even failed the NHS own app approval standards. With the app you've two options one , centralised with government or more likely private set up having all the data. Or two decentralised most of the data never leaves the phone 3rd party get's the bit's it need's to know the apple/google option.
The latter is what most other countries have gone for.
Apple for good reason do not allow any app that wants access to buletooth to run in the background. One it's a privacy issue and two it's like having your back door open and looking the other way as someone pockets your car key's. Knowing that something was coming Apple early on with google worked together on software that works and keep's everyone happy. Basically the the government want to control all of it inc the valuable data which it still won't say what it is going with. Germany early on wanted the same full on control but backed down in 24hrs after working out. Maybe Apple and google know best and trying with France to lean. On Apple to back down and let them have open season on users data.
We have a solution that we can have tomorrow which the Swiss and from yesterday Germany are using and it works.
A team at UCL helped the swiss with it months ago. The same team that contacted the government back in April to say your's will not work do you want help. They said it will and no thanks. What's more is it's open source so won't cost a penny.
