TimeTree does one thing very well: it gives families, couples and groups a shared calendar everyone can see and comment on, with per-event chat, memos and a web version — all free. Yuki starts from a different place. Instead of asking you to type events in, it connects to Gmail or Outlook and turns the confirmations, receipts, bills and invites already sitting in your inbox into a live calendar, trip itineraries, tracked expenses and tasks — then shares them with the people you plan life with. The goal is less about being a calendar and more about cutting the mental load of remembering and coordinating everyday life. If you mostly want a clean, shared, manually-kept calendar with group chat, TimeTree is an excellent fit; if you want that calendar to fill itself and carry money, trips and to-dos too, that is where Yuki differs.
