Split group trips without losing friends
Airbnbs, flights, restaurant tabs, and late-night ramen runs. Across 120+ currencies with real-time conversion. Settle up before your suitcase hits the floor.
The problem
Every group trip has a treasurer, and that treasurer is quietly fuming. They fronted $2,400 for the Airbnb, the rental van, and two big dinners, and three weeks later they've only been paid back $1,800. The receipts are crumpled in a hotel drawer, half the group forgot what they owe, and nobody wants to be the person sending the awkward 'hey, did you ever Venmo me for Lisbon?' follow-up. Trips should leave you with memories, not a spreadsheet and a grudge.
Built for group travel
Everything you need. Nothing you don't.
01
Airbnbs and shared stays
Split the rental by room instead of per head, so the two couples don't subsidize the solo traveler on the pullout couch. Add cleaning fees, service fees, and the security deposit once, and Supasplit handles who owes what down to the cent.
02
Restaurant tabs abroad
Snap the receipt, even if it's in Portuguese or Japanese. The AI scanner pulls every line item, tax, and tip in the local currency, then lets each person tap what they actually ate. No more 'I just had a salad' math at the table.
03
Multi-currency trips
Log the Airbnb in euros, the taxi in yen, the bar tab in baht. Supasplit converts everything in real time at the day's rate and shows a single running balance per person in your home currency. You never do mental math at 2am again.
04
Quick adds on the go
Hands full of gelato and bags? Say 'paid 40 euros for dinner, split with Max and Sam' and Supasplit logs it in two seconds. Voice entry is built for the moment you're leaving a restaurant, not sitting down with a spreadsheet at the end of the night.
Why it works
Features you'll actually use
120+ currencies with real-time conversion
Log expenses in the local currency of wherever you are. Supasplit converts to your home currency live at the day's rate, so balances always reflect what people actually owe.
AI receipt scanner for any language
Snap a receipt in Portuguese, Thai, or Japanese. The scanner extracts every line item, tax, and tip, so you can split by who ordered what in about 10 seconds.
Voice expense entry
Say 'paid 40 euros for dinner, split with Max and Sam' and it's logged. Perfect for adding expenses while walking to the next spot.
Smart reminders for post-trip settle-up
Supasplit nudges the people who owe money a few days after you land, so you don't have to be the one chasing everyone down in the group chat.
Split by room for Airbnbs
Couples in the master, solo in the pullout, bunk room for two? Custom split ratios handle unequal room situations without awkward side math.
Offline support
Airplane mode, patchy hostel Wi-Fi, a ferry with no signal? Add expenses offline and Supasplit syncs the second you're back online.

How it looks in real life
Real scenarios, real math
The 6-person Airbnb with 2 couples and 2 solos
The couples take the two bedrooms, the solos take the pullout and the bunk. Splitting the $1,800 rental equally isn't fair, but splitting by room is. Supasplit lets you set custom ratios once and every future Airbnb expense follows the same split.
The ski trip where everyone pays for different stuff
Lift tickets, rental gear, groceries for the cabin, après drinks, gas for the van. Five people each front different things. Supasplit tracks every expense and at the end shows one clean number per person, minus the chair-lift math.
The bachelorette in Lisbon with mixed budgets
Two people are flying from New York in USD, three from London in GBP, and the bride is already in Lisbon charging everything in euros. Supasplit converts everything live, so the maid of honor doesn't have to be a part-time currency trader.
The 'one person always fronts dinner' trip
One friend has the nicer credit card, so they keep swiping for the whole group's meals. By day three they've put $900 on their card. Supasplit lets them log each dinner in 20 seconds and get paid back the moment you land.

How Supasplit compares
supasplitvsSplitwiseSplitwise is the cross-platform workhorse with a huge user base. Supasplit is the modern iOS-native alternative with AI receipt scanning, voice expense entry, and no ads. Pick Splitwise if your group is split across Android and iOS or you need web access. Pick Supasplit if you want the fastest, cleanest experience and you're all on iPhone.
See the comparisonsupasplitvsRevolutRevolut's split-bill feature is a shortcut inside a banking app, not a real splitter. Supasplit is a dedicated splitter with AI receipt scanning, voice input, groups, running balances, and themes. If you're already on Revolut for banking, its splitter is fine for quick in-moment splits but doesn't replace a proper ledger for roommates, trips, or anything that runs over time.
See the comparisonsupasplitvsTricountTricount is the friendly European pick: genuinely free for core splitting, cross-platform, and simpler than Splitwise. Supasplit is the modern iOS-native alternative with AI receipt scanning, voice expense entry, and real personalization. Pick Tricount if your group is on mixed devices and you want free-forever basics. Pick Supasplit if you're all on iPhone and want faster entry, line-item receipts, and a polished app.

Frequently asked questions
How many currencies does Supasplit support?
Supasplit supports 120+ currencies with real-time conversion at the day's exchange rate. You can log expenses in whatever currency you paid in, and every member sees their balance in their home currency. Real-time conversion is included free on every plan, not locked behind Plus.
Can I use Supasplit offline on a trip?
Yes. You can add expenses, snap receipts, and view group balances offline. Everything syncs the moment you're back on Wi-Fi or cell data. Useful for airplane mode, train rides, ferries, and the dead zones between trailheads.
How do I split an Airbnb fairly when people have different rooms?
Use custom split ratios. If the two couples get the private bedrooms and the solos take the pullout, you can set a split like 35/35/15/15 instead of splitting evenly. Supasplit saves the ratio and applies it to every related expense (cleaning fees, service fees, security deposit) so you only set it once.
Does Supasplit work for bachelorette and bachelor parties?
Yes, this is one of the most common group trip use cases. Create a group, invite everyone, and log big shared expenses (Airbnb, dinners, activities) as you go. The running balance keeps everyone honest, and the maid of honor doesn't have to be the unpaid accountant for three months after the trip.
How do I settle up at the end of the trip?
Supasplit simplifies debts across the whole group, so instead of 12 separate transfers you might have three. Each person sees exactly who to pay and how much in their home currency. Supasplit doesn't process the transfer itself, you pay via Venmo, Revolut, or bank transfer, but the math is done for you.
How is Supasplit different from Splitwise for travel?
Supasplit includes real-time currency conversion and AI receipt scanning on every plan. On Splitwise, both of those are Pro-only ($3/mo). Supasplit also has voice expense entry, which Splitwise doesn't offer at any tier. The tradeoff: Splitwise runs on iOS, Android, and web, while Supasplit is currently iOS-only. If your group is all on iPhone, Supasplit is the faster, cleaner experience.
One tracker. Every trip. Zero drama.
Log expenses live, let Supasplit handle the currency math, and come home still friends. Free for small groups, $3.99/mo for unlimited.
