After breaking our heads over the product and lots and lots of interview with similar apps - we had an idea about how our product should look and feel like.
Initially two of the cofounders were convinced on having a web app for learning since they thought that proper learning can only happen over a laptop/PC. But after interviews with our target group, we found that no one likes to open their PC after their 996 shifts! Mobile screens and sometimes Tabs are the only media they like! So mobile app it is.
