Best shared expense app

I have lots of apps, but this is the first time I have felt the need to write a review.

This is hands down, the best shared expense app I have seen. It has an intuitive and intelligent GUI, and best of all -and the reason for the 5 stars- it is the only one where you can unevenly share expenses by using a coeficient: excellent! I have been looking for this feature for the longest time.

I just hope the developers are actively supporting and even improving the app.
