The problem FitFlex solves

Many small-scale fitness centers lack a platform to represent themselves and manage their plans effectively. This limitation prevents them from offering flexible subscription options, such as plans tailored for weekends or weekdays, to cater to users who are at different locations on different days. As a result, users who wish to maintain their fitness routines across multiple locations often face the challenge of high costs associated with subscribing to multiple fitness centers.

Challenges we ran into

The main challenge we faced was integrating the backend part with the frontend part. We were facing an issue where we were passing an empty array and not checking the condition in the code that would work for an array of data streams. We had a problem in fetching data, which was solved on adding use effect dependencies in React.
We also faced problems in designing database models which we solved after deep team discussions.
