More than 26,700 people responded to a survey to help the Evergreen Health app map how well different parts of the UK are sticking to the new measures.
Middlesbrough residents were the most likely to ignore government rules in the country, with around 25% of survey respondents saying they did not stay at home.
At the other end of the scale, the best people in Ryedale, North Yorkshire, were the best at 98.2%.
Meanwhile, 94.1% of Bristol residents follow lock rules and avoid going out unless necessary.
Respondents were also asked about the symptoms of Covid-19, such as if they had a dry cough or temperature and if they self-isolated.
The anonymized data is shared with the NHS and data scientists from the universities of Liverpool and Manchester to help them analyze the progress of the pandemic.

The developers of the app said that for an area of the country to appear on the map, there had to be enough people in the sample sizes for the percentages quoted to be statistically significant.
Users of the app also receive advice on how to protect themselves during the crisis, with personalized advice from the NHS to those who are considered to be at greatest risk of complications from the virus.
Dr. Ian Hall of the University of Manchester said: “The respondents support a better understanding of the local experience of Covid-19 disease by sharing their data, which will be extremely useful for national and local planning.
“This is an exciting emerging data flow and I look forward to helping interpret the data, with colleagues from Manchester and Liverpool, as it provides situational awareness to users and decision makers.”
