Lunch is approaching and it's time to introduce you to a new service -
obeder.ruOriginally made it for personal use. Tired of confusing when paying for dinner, who is to pay today and who owes whom.
The idea is simple:
')
Pays one, the amount is equally divided into all those who had dinner.
The one who paid the balance rises in plus, the others in minus.
Who has the "deepest" minus - pays the next time.
It is possible to take into account differences in the price of lunch, the absence of some "diners", to distribute debts. A log with the ability to roll back.
It is convenient to use in mobile browsers, and of course you can take into account any common expenses.
Under the cut - a picture with an explanation.

UPD1: Thanks so much for the feedback!
UPD2: Small explanation:
This implies the use of the service in the company of colleagues.
In addition to lunch, we celebrate the order of pizza for everyone, tea-coffee-donuts to the office, go-karting, etc.
I do not urge to start dinner for settlements with my wife or friends (everything is much easier with them)
