The problem LP Underlying Calculator solves

The LP token balances are not very intuitive for the end-users.
This easy-to-use calculator allows them to find what the underlying token balances correspond to their LP tokens.

For example, a balance of 100 UNI-V2 LP tokens for DAI-ETH does not mean that it's 50 DAI or 50 ETH, it requires calculations to be done which the user can easily evaluate via this tool.

So these 100 LP tokens can then correspond to say 4000 DAI + 3 ETH

Challenges I ran into

Using Material UI with React took more time than expected.
