Keep track of pennies
This may be a bit pedantic, but the splitting should keep track of remainder pennies across expenses and itemized bills within, to keep it more fair. For instance, if you have an itemized bill with multiple charges of 0.99, and split between two people, in each item, whoever's first pays the extra penny (0.50 / 0.49). This means that if you have a lot of these expenses in one bill (e.g. 99p Stores here in the UK), the bill gets more and more unevenly split based on nothing but alphabetical order of the splittees' names.
Update: all of our apps should now redistribute pennies randomly. Tracking pennies is fairly complicated and unlikely to be much better than random distribution.
Sorry for the trouble! The way we split pennies is a bit inconsistent based on which version of our app you’re using, but we do generally try to be fair, usually by distributing the extra pennies randomly. This is definitely somewhere we want to keep improving – for now, apologies for the inconvenience!
