I don't use it, I had to self isolate for 14 days after an 11 day stay in Hospital (not Covid related) because 2 people on the ward tested positive, we all had to have a negative test before admission. I was tested 5 times during my Hospital stay, all negative.
In early March I was told to shield until 31st March
, my health conditions hadn't changed since the 1st lockdown. I was attending my GP Surgery every other day, this caused them a lot of extra work.
I have no wish to self isolate again, DD removed it off her phone after some-one told her that once she had checked in to Martial Arts the app presumed she was there all evening not just for an hour. Potentially if some-one tested positive in later classes she would have to self isolate along with her Partner & DGSs even though she couldn't have come into contact with them
I will continue mask wearing, social distancing, sanitzing & avoid crowded places. I need to attend all my medical appointments both to help heal my severe Cellulitis & for my mental health
