After 10 days, we provided the MVP of the application, which was promptly developed in Rubi. In the first days it became clear that the application was complicated and it was necessary to implement logic for displaying questions, when the interviewer noted the absence of a particular product, it was necessary to hide these questions and display this in the report table. In 4 days this was implemented.
Also errors of saving questionnaires in conditions of no mobile Internet on the interviewer's device were fixed. We also solved the problem of saving a large array of photos.
Over 10,000 retail outlets throughout Uzbekistan were interviewed using our app.
