Thanks for the detailed feedback – it’s always useful to hear, and I’ll pass it on :)
One small feature you may not be aware of: on our website, Splitwise does allow you to add group members without email addresses, which hopefully helps for the “large party” scenario. My apologies that the same feature isn’t available on our mobile apps!Koen commented
It would be handy if we can add non splitwise entities to a certain cost so that a part of the cost can be assigned to these without them needing to have an actual account.
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.Koen commented
maybe support the use of hash tags which you can also use in statistics, then you dont have to allow more. categories but make a statistics view based on provided hashtags so people can control their categories themselves. add the amount specified to each hashtag provided and make an overview page of that
We just added a very basic calculator function to our web app, so you can now use basic mathematical operations when entering a cost (addition, subtraction, multiplication, and division). We hope to add similar features to our mobile apps at some point in the future!
