Here is my first public app : RestoDiv. With the hope it could be useful for someone else.

It should help you to divide a bill. You set the bill, and add groups of payers : it will divide it by group. An adult is a full part, a child is a demi part. A group can decide to pay by tickets : just hit the part of the group and set the amount for the ticket.

On small screens, swipe-right to remove a group (on bigger : a button is available for that).

It works offline, and should work on any smart(html5) devices (smartphones, tablets, smart tv, computers, ...)

I don't know yet if I will release a cordova/apk for the playstore.
