About Flatwise
Flatwise helps you organize everyday tasks, events, and shared expenses – on your own, as a couple, or in a group. YOUR DAY AT A GLANCE The new Home feed brings together tasks, events, and outstanding balances. See what’s on today, what’s overdue, and what’s coming next. STAY ON TOP OF TASKS Plan tasks with due dates and repeat schedules, assign them to members, and keep track of what still needs to be done. PLAN EVENTS TOGETHER Organize personal and shared events with repeats and reminders. Switch between month, day, and list views, and choose which groups and people you want to see. GET ORGANIZED TOGETHER Create private groups for your partner, housemates, or friends. Invite others with a link, QR code, or invitation code. Shared tasks, events, and expenses stay synced across members. SPLIT EXPENSES FAIRLY Record who paid and how you want to split the costs. Keep track of expenses, outstanding amounts, and recorded repayments. Clear balance breakdowns show you how each amount is calculated. Optional debt simplification makes settling up within your group easier. MAKE FLATWISE YOUR OWN Choose the features you want to use: tasks, events, and expenses can be combined independently. MORE WITH FLATWISE PLUS Connect Apple Calendar to view and edit existing events directly in Flatwise. Export Flatwise events and selected tasks to Apple Calendar, and use widgets for a quick overview. Flatwise Plus is available as a one-time in-app purchase – no subscription.
