Each of them is good at one part of a group trip. Roamer covers all three — and adds the social side none of them have.
Most groups end up running two or three apps for one trip: something for the itinerary, something for the money, and the group chat where the actual conversation happens. Each app is fine. The problem is that the expense and the dinner it paid for live in different places, and the decision that led to both is in a third.
Here is the honest version of how the four compare, including where the others are genuinely better.
All four ship changes regularly — check the current feature list for anything that decides it for you.
The best pure expense splitter, and it isn't limited to travel — it handles ongoing balances between flatmates or a couple indefinitely, which Roamer deliberately doesn't. If the money is the only thing you need to coordinate, or your group has years of history in it, keep using it.
What you give up is context. The expense sits in a list, away from the dinner, ferry or stay it paid for, and away from the conversation where the group agreed to it.
Ongoing balances that outlive a single trip
Hold the plan the expense belongs to
Strong at the part before the trip exists: place discovery, guides, routing and drive times, all on a proper desktop web app. If you're still deciding what to see, or planning a multi-stop road trip at a laptop, it's better at that than we are — we have place search, not recommendations, and no web app at all.
Where it thins out is the group. Comments aren't a chat, and budget tracking isn't expense splitting.
Recommendations, routing and desktop planning
Split money or host the group conversation
Built around one very good trick: forward a confirmation email and it becomes an itinerary, no typing. For a frequent solo traveller with a lot of bookings that's hard to beat, and its offline itinerary access is mature.
But it's fundamentally a personal tool. There's no expense splitting and no group conversation, so on a trip with five other people it holds the flights and nothing else that trip generates.
Turning confirmation emails into an itinerary
Almost everything a group does together
It covers the itinerary, the map, the documents and the money, and then adds the part none of the others have: the trip's social life.
If you plan at a desk in eleven browser tabs, we don't have a web app and that will annoy you. If you want a tool to tell you what's worth seeing, Wanderlog does that and we don't. And if your group's Splitwise history goes back years, moving it isn't worth the trouble — use Roamer for the plan and leave the money where it is.
What tends to happen after one trip is that the second app stops getting updated around day three, because the expenses were already going in as people logged the plan. That's the real argument for consolidating, and it's easier to feel than to be told.
