I absolutely love this app and the idea behind it. It takes all the stress out of what can sometimes be a very difficult subject between friends and loved ones and simplifies life. It's also a great way of keeping track of just exactly how much money you're spending.
Tricount is an application that allows you to keep track of shared expenses whether it be on a group holiday, with a flatmate, organising parties or even in your relationship. You can also use it to manage your own personal budget.
The app has a simple, user-friendly interface, you just share a link with your friends and you’re ready to go. You add the amount of money you have spent in the currency of your choice and note if it is a personal or common expense. Other group members will do the same and the app will do the accounting for you, informing you who owes what and to whom. Tricount even works offline so you can use it in the most remote locations, such as sipping cocktails on a beach.
