The plan lives in five places
A screenshot in the chat, a note on someone's phone, a spreadsheet only one person opens, and two things that were only ever said out loud. Ask three people when you're leaving and you'll get three answers.
Festivals, road trips, weekend getaways. Lumela puts the plan, the money, the map and the people in one shared space — so nobody has to scroll back through 400 chat messages to find the meeting point.


They fall apart in the three weeks before it, in a chat where six people are answering three different questions at once.
A screenshot in the chat, a note on someone's phone, a spreadsheet only one person opens, and two things that were only ever said out loud. Ask three people when you're leaving and you'll get three answers.
One person fronts the cabin, another buys all the groceries, someone pays for gas twice. Three weeks later nobody remembers the numbers, and asking feels rude — so it quietly gets dropped.
Fifty thousand people on one cell tower, or a canyon road with one bar. That's exactly when you need the address, the ticket and the meeting point — and exactly when the chat won't load.
Not a chat with extra buttons. Five focused screens that each solve one part of travelling as a group.
Add what you paid the second you pay it. Lumela handles the arithmetic — including the messy kind, where four people split dinner but only two of them had the wine.

Departure times, set times, check-in, the dinner reservation someone made in March. Day by day, in order, with reminders that reach everyone's phone instead of one person's memory.

Save the campsite, the parking spot, the viewpoint someone swore was worth the detour. Then, when it matters, turn on live location so the group can find each other without ten phone calls.

Who's bringing the speaker, the cooler, the tent poles that were left behind last year. Shared lists everyone can tick off, with an approval step for the tasks that matter.

Entry tickets, the cabin confirmation, insurance, a photo of the passport page. Stored for the group and downloaded to the device in advance, so the gate doesn't become a problem.

No onboarding marathon, no credit card, no 'invite your contacts' screen.
Name it after the trip. That group becomes the shared space for everything below — and you can be in several at once, because life has more than one trip in it.
One link in the chat. Tapping it joins the group directly; if someone doesn't have the app yet, the link takes them to install it and then straight into the group.
An event, an expense, a place, a packing item. Everyone sees it instantly, in their own language, on iPhone, Android or the web.
Some of these took months to get right. They are the reason the app holds up on day three of a festival.
Your trip is cached on the device and edits queue locally. Add an expense in a dead zone, and it lands in the group the moment you have a bar again — with no duplicates.
No ads and no data sales. Location is opt-in and group-scoped. You can delete your account and its content from inside the app — no email thread required.
Fully translated, right-to-left included — down to the widgets and push notifications. Everyone reads the same trip in the language they think in.
Home-screen widgets for what's next, a Live Activity while an event is running, Apple Watch, CarPlay for saved places, and Siri shortcuts for adding things hands-free.
Someone joining for one night still belongs in the split. Add them as a guest — no account, no install, and the math still works out.
Ask what's on tomorrow or add three reminders in one sentence. The assistant only ever sees the group you're in, and can only create things — never quietly change them.
The needs change; the chaos is remarkably consistent.
Twenty people, no signal, five stages and a camp nobody can find in the dark. Live location, offline tickets and the official line-up inside your group.
Gas, tolls, a cabin split four ways and a route that changes twice a day. Keep the stops and the receipts in the same place as the plan.
Flights, apartments, and eight people in three timezones trying to agree on dinner. Shared documents, per-event timezones and one honest balance sheet.
Real screens from a real trip — not a mockup with lorem ipsum.



Practical writing about planning, splitting and surviving trips with other people.
A practical system for splitting trip expenses with friends: what to log, how to split unevenly, multiple payers, and why trust beats the maths.
Who owes who what after a trip: simplified debts vs pairwise balances, why the "optimal" answer feels wrong, and a four-minute script for settling up.
A festival packing list for groups, split into what each person brings and what the camp shares — plus the eight items every group forgets, every year.
Yes. Creating groups, planning, splitting expenses, sharing location and everything else in the app is free — no ads, no trial timer. An optional Lumela+ subscription is planned for people who want bigger groups, more groups at once and a managed AI assistant.
iPhone via the App Store, Android via a direct APK download (Google Play is on the way), and any browser through the web app. Everyone in a group can be on a different platform — it is the same trip.
Members who want to see and edit the trip do. But you can also add guests — people who are part of the trip and part of the expense splits without installing anything. Useful for the friend who joins for two days, or the one who never installs apps.
Yes — this was a design requirement, not an afterthought. Lumela is offline-first: everything you already loaded stays readable, and anything you add offline is queued and synced the moment you have a connection again. Festivals and mountain roads were the test cases.
No. Location sharing is opt-in, per group, and you turn it on when it is useful and off when it is not. It is never shared outside the group and never sold anywhere. Most groups switch it on for a few hours at a festival and forget about it the rest of the year.
A chat is a stream — the important message is always scrolling away. A spreadsheet is structured but nobody opens it on the road. Lumela keeps the structure of a spreadsheet with the immediacy of an app: the plan, the money and the map are always one tap away, on everyone's phone, in their language.
