Weighted families — unique to Tabby
Age-based child weights on equal splits (and settle as one household). Other split apps treat every headcount the same — Tabby doesn’t make a toddler “owe” like an adult.
Only Tabby · weighted family splits·iOS & Android
Split the tab. Spark joy.
Zero drama.
Tabby is the expense app for friends, families with kids, and trips. Fair splits that know a toddler isn't an adult, settle-up that makes sense, and no spreadsheet anxiety — a feature set no other split app matches for households.

Weighted families: fair splits when kids are in the group
Every other split app treats people as equal headcount. That's fine for roommates — terrible for a family dinner. Tabby lets you link a household into a group: kids get age-based weights on equal splits, and you settle once through the head instead of chasing every child for £3.40.
- ✓Default child weights by age band (editable) — or freeze a custom % per child
- ✓“Equal” split uses weight units, not headcount — a 0–3yo can be 0%
- ✓Family chip on the split roster; expand only when you need to leave someone out
- ✓Orbit & ledger roll the household to the head so one settlement clears everyone
If you split with kids, this alone is why Tabby exists.
Example · €270 dinner
Two adults + Leo (8) + Mia (4) · equal by weight
Carlos100% → €100
Maya100% → €100
Leo · 850% → €50
Mia · 420% → €20
Total weight 2.7 — not “4 people × €67.50”. Other apps can't do this. Settle the whole household with the head when you're ready.

Features
Everything you need after someone says “I'll get this one”
Tabby is more than a shared total. It remembers the messy bits — weighted families, multi-payer dinners, trip days, and the minimum payments to make everyone square.
🧾
Split any way you want
Equal, percent, custom amounts, or itemized lines. Multi-payer bills so more than one person can front cash on the same expense.
🪐
Settle-up orbit
See who owes whom at a glance. Tap a person, record how you paid outside the app, and watch the balance clear — no awkward spreadsheets.
✈️
Trip mode
Turn a group into a trip dashboard: day-by-day spend, categories, who paid, and a clean path to settle when you’re home.
🔗
Invite in seconds
Share a code, link, or QR. Friends land on a page that opens Tabby or sends them to install — then they’re in the group.

Why Tabby
Catchy cat. Serious about fairness.
We built Tabby for the moments after dinner, during the trip, and when the group chat starts arguing about “who paid for the Airbnb.” Clarity first — then a little joy.
Meet the mark
Top hat. Balance scale. Cool smirk. The paper-cut cat is our reminder: keep the books honest, keep the friendship light.
Weighted families (only Tabby)
Age-band child weights on equal splits + settle-to-head households. The feature other split apps simply don’t have — fair for kids, simple for parents.
Built for real groups
Not a bank. Not a payment processor. A calm ledger for the people you actually split with — friends, families, flatmates, trips.
Honest math
Shares, multi-payer, settlements, and simplify all follow one ledger plan so Home, group cards, and settle-up stay consistent.
Native on both phones
SwiftUI on iOS, Compose on Android — fast, offline-friendly, and designed for the way you already use your phone.
Ready to split without the awkward math?
Install Tabby on iOS or Android, create a group, and invite the crew. Your next dinner — or your next trip — will thank you.
