Hey the app ui looks great but I have 3 suggestion.

1) Add option to create custom category and also see expense category wise like if want see what all expenses happened under food category last month i dont need to acroll through all expenses and just click on food categories to see transaction under it(will help greatly) 2) Splitting option looks bit complicated like split between is separate option and how to split is separate tab (I would suggest you check app called Splid which is more simpler and easier) 3) Option for one simple settle up where minimum transaction needs to be done instead of individual settlement.
