A surprise party that stays a surprise
The group is created without the birthday person. The meeting point is pinned at the top of the chat, and everyone knows who's bringing the cake and who's on playlist duty.
Use case
A group for the length of an event: pick the date, collect the money, know who brings what, then share the photos. Even when the guests don't know each other.
Picked for what you actually share.
The organisers' or all the guests' chat: a pinned message with the address and time, photos, voice notes.
Which Saturday for the hen do? Which restaurant? Suggest several dates, everyone votes, the best one wins.
The schedule for the big day and the prep: everyone RSVPs and gets a reminder.
The couple's gift or the hen do activity: everyone states their share, the organiser tracks what has come in.
Drinks, desserts, decorations: everyone signs up for what they'll bring, and the summary shows what's missing.
Every guest's photos in one place, sorted into pages: ceremony, party, the morning after.
YouTim brings all your group's tools together — chat, calendar, budget, photos and more — in one place.

What it looks like day to day.
The group is created without the birthday person. The meeting point is pinned at the top of the chat, and everyone knows who's bringing the cake and who's on playlist duty.
A poll for the date, a fund for the activity, a pinned message with the plan. University friends and cousins get organised without knowing each other.
Each guest adds their photos to the gallery, sorted into pages. The couple get them all without chasing anyone.
