provide option for user ids also
Instead of inserting email id everytime you can also create user names, email id should be mandatory for the first time for verifing after that user can login using their Usernames also

I’m not completely sure what you mean here, but I’m assuming you want the ability to add use nicknames for use in the app to add them to expenses? You should already be able to search by name in the fields to add expenses and it should find friends already on Splitwise first.
