Free app for group travel expenses

Hi there! Every year, I go on vacation with my family (there are a lot of us), and we used to use Splitwise. With their recent updates, we’re a bit frustrated because we’re limited in adding our expenses. Do you have any other alternatives (preferably free ones)? My son suggested Tricount, but I’ve never heard of it before! PS: If you have any tips for Mexico City this year, we’d love to hear them! Thanks!
