By default, doses within a one minute delay will be grouped as one, and first purging dose (2 units or less) will be hidden. Click on a grouped dose to display the details. Long click on the details to delete doses. Source code available at https://github.com/lcacheux/nov-open-reader This application is not developed or endorsed by Novo Nordisk.
