The Happy/Angry Bill Calculator is a fast, easy and fun way to split the cost of a meal and tips between friends.
Simply enter the total amount, how many people, and decide how happy you are with the service - the App will tell you how much you need to pay each (including tips), and it'll round it up for you for convenience.
It also provides a breakdown of the total amount to pay, how much tip you are paying, and how much tip each person is paying.
The tip it adds will vary between approximately 0% (ANGRY!) and 20% (food heaven!) depending on your happiness with the service (the background colour reflects your happiness too!), or just leave it in the middle for a standard 10% tip. The exact figure will vary a little, because the amount each person pays is rounded up for your convenience and this adds a small amount to the total.
When you enter the bill amount, enter only the figure (for example 76 or 104.12), currency symbols are not required.
If you need a reminder, just click on the i button for simple instructions inside the App.
