Challenge 1- To keep this process very simple and understandable was quite challenging. There are hundreds of applications out there with the same goal and use. But through proper user research(interviews, testing etc) I was able to find the perfect solution for this problem.
Challenge 2- While conducting the initial interviews and researching, I came to understand that if people wanted to buy something or invest in something, they faced a lot of problems because they could not properly plan how to save for their goal and how to keep track of the progress. So for this I designed and tested this feature to help the users set their goals and to keep them reminded of the same.
