Flights: routes and times now show the right way round, and dates and times are clearer. Booking reference, flight number and ticket are optional. Airport search is better, and saving an edit takes you back. A loading overlay shows while saving.
Activities: activities can have an end date and an "All Day" option. They show as "All Day · date range" on the detail screen and in the itinerary.
Hotels: the stay length follows check-in and check-out, and the +/- stepper moves the check-out date.
Reminders: notifications show the title and your local time, and tapping one opens the right group. The reminders list on the dashboard now shows properly.
Invites: joined invites are handled, and My Herds shows the right groups after you join.
For You: a quiet feed now shows a helpful card with the right button, such as "Add more days", "Invite friends" or "View plan". Tapping the card opens its group.
Sign in with Apple or Google: if your account doesn't have a real name yet, the app asks for it. You can skip it for now, and it asks again next time.
