I think there’s a great way to achieve this whilst conforming to Mondo’s minimalistic UI.
Take the example below:
Just a small Split Bill button. Clicking it brings up your list of contacts, and runs the same logic as sending a payment (checking they are active Mondo users).
Potentially multiple select users and clicking Request Split, then being shown a page with the list you have selected, percentages or flat values, and later whether they have accepted or declined.
The major benefit for me here isn’t the moving of money itself, it’s being able to see what I’ve spent.
Often I will pay for the whole dinner, and then money is transferred to me afterwards… just to make paying a little smoother. But it looks like I’ve spent a whole lot more than I actually have on food by the end of the month.
You guys already have this on your roadmap, and I’m sure you will come up with a great implementation anyway, just my two cents!
