A quiet running tally of 'us'
Track shared rent, groceries, date nights, and dog vet bills between partners. 50/50, proportional, or yours-mine-ours. No scoreboard, no pressure, no keeping track in your head.
The problem
One of you fronts Thursday date night six times in a row before remembering the other was supposed to get this one. At bedtime, someone mutters 'wait, did I pay you back for the dentist?' and neither of you can actually remember. The shared Google Sheet starts as a cute joke and slowly turns into the thing you argue about on Sunday nights.
Built for couples
Everything you need. Nothing you don't.
01
Shared bills you barely have to think about
Rent, utilities, streaming, the grocery run. Log them once, Supasplit keeps a quiet running balance in the background so neither of you has to hold it all in your head.
02
Proportional splits when one of you earns more
If incomes are uneven, a 50/50 split quietly stings the lower earner every month. Set a proportional split once ($4,500 vs $7,500 means roughly 38/62) and let every expense use it by default.
03
Date nights and the in-between stuff
Dinner out, the airport Uber, that impulse plant from Trader Joe's. The tiny expenses add up fast. Tap them into your 1:1 balance in a few seconds and settle up whenever you feel like it.
04
Tracking without the spreadsheet energy
Your living room shouldn't feel like a month-end close. Supasplit shows one clean balance on the home screen, no red dots, no nags, no 'you owe me' vibes.
Why it works
Features you'll actually use
Any split method
Equal 50/50, proportional by income, custom percentages, or one-off adjustments. Set a default for your couple and override only when you want to.
Quiet running balance
No buzzing alerts, no payment requests, no scoreboard energy. Just one calm number you can glance at whenever you actually care.
AI receipt for the grocery run
Snap the Trader Joe's receipt and Supasplit reads every line item. Split by who actually wanted the oat milk, or just toss it all in as shared.
Multi-currency for international couples
Partners in different countries, or one of you traveling? Log expenses in any currency with real-time conversion, free tier included.
Shared subscriptions tracked once
Netflix, Spotify, the gym, iCloud storage. Set them up as recurring shared expenses and they flow into your balance automatically each month.
Personal notes on expenses
Add a note to any expense so future-you remembers the context. 'Anniversary dinner, your half is my gift' saves a conversation six months later.

How it looks in real life
Real scenarios, real math
Moving in together
First shared bills, first joint grocery runs, first 'how are we actually doing this' conversation. Set up a 'Household' group, decide on yours-mine-ours vs a joint account setup, and Supasplit becomes the honest record you can both see.
The proportional split when incomes differ
One partner makes $4,500 a month, the other makes $7,500. A 50/50 split on rent quietly drains the lower earner. Set a proportional default (about 38/62 here), and every expense respects it without either of you having to do the math.
Date night rotation
Some couples want to alternate who pays. Some want one person to pay and reconcile monthly. Either way works: log who covered the check, Supasplit keeps the running tally so the 'it's my turn, right?' question stops being a guess.
The annual money check-in
Once a year, most healthy couples sit down and look at the numbers together. Supasplit gives you a clean, honest snapshot of the last twelve months so the check-in is about conversation, not detective work.

Frequently asked questions
Do we really need a bill-splitting app if we're married?
Only if it makes your life easier. Plenty of married couples merge everything and don't need this. Others keep separate accounts for independence reasons, or share some categories (rent, groceries) while keeping others personal (clothes, solo hobbies). If your household falls into that second bucket, Supasplit quietly handles the shared slice so neither of you has to keep a mental ledger.
How does proportional splitting actually work?
You set each partner's share once as a percentage. If one of you earns $4,500 and the other earns $7,500, the lower earner covers about 38% and the higher earner about 62% of shared expenses. Every shared expense then uses that default, and either of you can override it for a specific expense (like a gift from one partner to the other). You can revisit the percentages anytime raises or job changes happen.
Can both of us see the same balance?
Yes. When you invite your partner to a shared group or 1:1, you both see the same live balance, the same expense history, and the same notes. Supasplit syncs between your phones so there's no 'let me check mine' moment. It's one source of truth for the 'us' finances.
What if we have a joint bank account for shared stuff?
Supasplit still helps, just a little differently. A joint account handles the cash flow, but you often still want a record of who paid for what from their personal card, who Venmo'd the dog walker, or how much each of you put in this month. Use Supasplit as the lightweight ledger on top of the joint account, not a replacement for it.
How is this better than a shared note on our phones?
A note doesn't do math. It doesn't know about proportional splits, doesn't convert currencies, doesn't give you a running total, and doesn't remind you about the $80 you fronted three weeks ago. Supasplit does all of that in the background, and it looks nicer than a bulleted list your partner keeps accidentally deleting.
Is Supasplit better than Splitwise for couples?
For iPhone-only couples, yes. Supasplit has AI receipt scanning on the free tier (Splitwise paywalls OCR), no ads, real-time currency conversion, and a more modern feel for a daily-driver app. If one of you is on Android, Splitwise is still the safer pick because Supasplit is iOS-only today.
