Everything you need to know about using CostSplit
Creating a group is simple. Open the app, tap the "+" button or "Create Group" on the home screen, give your group a name (e.g., "Summer Trip 2026" or "Apartment"), and optionally add a description and choose a currency. You can then invite members by sharing an invite link or adding friends directly from your contacts.
