Tricount

Tricount is an app that lets you keep perfect track of all the shared expenses you have in your life. And best of all, it even lets you link your PayPal account to pay your share directly from the app.

Using Tricount is very simple. All you have to do is create a new 'tricount' where you can add as many users as you want. From the new 'tricount' you can also add as many expenses as you want, and the app will take care of splitting the cost equally among the users.

From the app, you can use PayPal to make payments. Alternatively, you can also simply mark a bill as paid as long as you've already paid it. Plus, since the app is synced with all the users, everyone can see who has and hasn't paid their part yet.

Tricount is an excellent way to see who's paid their dues. It's a useful tool for all those dinners with friends where there's always one person who sneaks out without paying ... and for shared apartments to make sure all the roommates are pulling their weight.
