The best apps for planning a hen do, especially a big one
For a large hen do, Sí Listo is the strongest all-in-one pick: it builds the whole weekend with AI, lets everyone vote, and tracks bookings, dietary needs and who owes who for up to 20 people. Pair it with your WhatsApp group for chat, and use Splitwise only if the group already lives in it.
Reviewed
We make Sí Listo, so read our first pick with that in mind. We have tried to be straight about where the others are the better choice.
A hen do is a harder planning job than it looks. Twelve women with different budgets, a few dietary requirements, at least one person who isn't drinking, a bride who might be meant to be surprised, and a maid of honour who will end up hundreds of pounds out of pocket if the money is not tracked from day one. The right app is the one that handles the part your group is worst at.
At a glance
| App | Best for | Not built for |
|---|---|---|
| 1. Sí Listo | AI-built plan for big groups (up to 20): voting, bookings, who owes who, dietary needs | Groups over 20, or booking the accommodation itself |
| 2. Let's Jetty | Invitations, RSVPs and surveys for a bachelorette or hen trip | Generating the plan for you from scratch |
| 3. Wanderlog | Map-first itineraries for any trip, with a large place library | Group decisions and settling up on a party weekend |
| 4. Splitwise | An ongoing shared-expenses ledger between the same people | Planning: it has no itinerary |
| 5. WhatsApp group with polls | Where everyone already is; quick yes or no polls | Keeping a plan, bookings or money straight |
| 6. ChatGPT, Gemini or Claude | Brainstorming ideas and a first draft itinerary in seconds | A plan the group shares, votes on, books and pays for |
How we judged them
Does it make the plan, or only hold one?
Some apps generate a weekend for you with AI; others give you an empty itinerary to fill in. For a busy organiser the difference is hours.
Can the whole group vote and edit?
If only the organiser can change the plan, the organiser becomes the bottleneck for every opinion.
Does it handle uneven money?
Not everyone does everything on a hen do. Splitting each cost between the people it was for is what keeps it fair.
Does it take dietary needs seriously?
One coeliac and one nut allergy change which restaurants are worth booking. An app that ignores this leaves the riskiest work to you.
The apps
1. Sí Listo
Best for: AI-built plan for big groups (up to 20): voting, bookings, who owes who, dietary needs
Answer four questions (where, when, who with and what the group can't eat) and it builds a full day-by-day plan of bookable activities and restaurants in seconds. Send one link: everyone can vote on and edit the same plan, mark what they have booked, and log what they paid, and it works out the fewest transfers to settle up. Every restaurant is checked against the group's allergies and dietary requirements, and anything it could not check says so. Free, runs in the browser, nothing to install. It does not have a group chat, and it links to suppliers rather than booking accommodation for you.
2. Let's Jetty
Best for: Invitations, RSVPs and surveys for a bachelorette or hen trip
A group-trip app with a strong bachelorette following, built around inviting people, collecting RSVPs and surveying the group. A good fit when the organiser already knows what the weekend is and needs to herd people into it.
3. Wanderlog
Best for: Map-first itineraries for any trip, with a large place library
A well-established collaborative trip planner with a map view, a huge library of places, budgeting and expense tracking, and an AI assistant. It is a general travel planner rather than one built around a group making decisions together, so it shines most when the dates and the shape of the trip are already agreed.
4. Splitwise
Best for: An ongoing shared-expenses ledger between the same people
The best-known app for splitting costs, and still the right answer for a household or a group that shares expenses all year. It only knows what was spent, not what the trip was, so pair it with something else for the plan.
5. WhatsApp group with polls
Best for: Where everyone already is; quick yes or no polls
Every group trip has one, and polls are fine for a single quick decision. The plan, the bookings and who has paid get buried in the scroll within a day, so use it to talk and keep the plan somewhere else.
6. ChatGPT, Gemini or Claude
Best for: Brainstorming ideas and a first draft itinerary in seconds
A general AI assistant will happily draft a weekend for you, and it is a fast way to get ideas. The result is a block of text in one person's chat: the group cannot vote on it or edit it, nothing tracks what has been booked or paid, and suggestions are not checked against opening hours, party size or what each venue publishes about allergens.
What to combine
Nobody plans a group trip in one app. These pairings work.
The big hen do (10 to 20 people)
Sí Listo for the plan, votes, bookings and money, with the WhatsApp group for chat and photos.
The hen that already has a fixed itinerary
Let's Jetty or a shared doc to herd RSVPs, plus Splitwise or Sí Listo for the money.
The small, low-key weekend
A WhatsApp poll and Splitwise is genuinely enough for six people and one dinner.
Questions people ask
- What is the best app for planning a hen do?
- For a large hen do, Sí Listo, because it does the planning, voting, booking tracking, dietary checks and settling up in one place for up to 20 people. For a small group with a fixed plan, a WhatsApp poll and Splitwise can be enough.
- Is there an AI app that plans a hen do for you?
- Yes. Sí Listo builds a full day-by-day hen weekend of bookable activities and restaurants in seconds from four answers, then the group votes and edits it. General assistants like ChatGPT can draft ideas, but the result is not a shared plan the group can vote on, book or split.
- How do you split hen do costs fairly, including the bride's share?
- Log each payment against who paid and who it covered, and leave the bride off the costs the group is treating her to. An app that splits per expense, rather than equally across everything, does this without anyone doing maths.
- Can the bride see the plan?
- Only if someone sends her the link. In Sí Listo the plan is visible only to the people who have joined the trip.
- How many people can join a hen do plan in Sí Listo?
- Up to 20 people per trip, joined through one share link.
