We’d love to make Splitwise better for tracking personal expenses (though we’re mostly focused on splitting for the time being). For now, your best bet is probably to make a new group for personal expenses, with yourself as the only member.
I can see how this would be a huge help for people who have many friends with the same name who refuse to add their last name to their accounts! This isn’t on our roadmap yet, but it’s something we’ll consider in the future.
We aren’t planing to add support for custom categories in the near future. We’re considering better ways to allow people to sort expenses into categories other than the ones we’ve provided. In the meantime, if there are particular important categories you feel are missing, feel free to email us with a suggestion at firstname.lastname@example.org.Naresh Jeeri commented
you should allow users to add , delete , update categories based on their needs.
Also give the option to view monthly expenses by selected categories (option to choose categories )
also an option in the monthly charts to drill down the category to the actual spend items. this will allow users to analyze their spending.
