Why ODMERA started

ODMERA started the way most useful things do: out of frustration with something ordinary.

Anyone who's ended up as "the organiser" knows the feeling: chasing opinions across three group chats, trying to remember who said they'd pay for what, and still missing something important. At one of our own weddings, after what felt like careful planning, two guests were missed off a table entirely. A small mistake, easy to avoid with the right tool, but invisible until it was too late.

That's the gap ODMERA was built to close. Not another group chat, and not another spreadsheet, but one place where the group can see where things stand: what's been decided, who's coming, who's staying where and what's still open.

Even the name is personal, made from the names of the people behind it. ODMERA is still early, shaped by the people testing it and the real weekends away, nights out and get-togethers it's used for.

What it does

A group trip planner for weekends away, stag and hen dos and group holidays. Groups stay together after the event, so the next one doesn't start from scratch.

Groups
Your family, your five-a-side, your old flatmates. Each group keeps its events and history.
Going or not
Going, maybe or can't go. Everyone sees the count, so nobody has to ask twice.
Suggestions and votes
When the host opens it up, guests can put forward places and ideas and vote on them. Once it's settled, it's marked Decided.
Which day?
Everyone picks the days they can do. You see which day works for most people.
Tasks
Who's booking the minibus, who's sorting the food, and what's still open.
Shared costs
Split costs for the trip and keep track of who owes what. You pay each other directly. ODMERA never holds your money.
Event chat
Each event has its own chat, and the host picks how open it is.

Coming later: children's parties, weddings, festivals, tours and backpacking trips.
