A household ledger, kept quietly
Everything you share, kept — not tracked.
Kin tracks the money, the dues, and the pantry in your household, and syncs it phone to phone over Bluetooth. Nothing goes to a server, because there isn't one.
No account · no cloud · no ads
Kin isn't on the Play Store — it's a direct install. Android will ask you to allow installs from this source once; that's expected, and it's the same trade-off that keeps Kin off any app store's servers.
How it works
Three habits, not a setup process
Kin isn't something you configure once and forget. It's something you and the people you live with keep, together, a little at a time.
Track together
Log an expense, a payment, a bag of rice running low. Anyone in the household can add or edit an entry — every change is signed with who made it and when.
Sync nearby
When your phones are near each other, Kin syncs directly over Bluetooth. No wifi required, no background connection, no syncing while you're apart.
Stay private
There's no server to sync to in the first place. Your household's ledger lives only on your household's devices — and stays that way.
Inside Kin
One screen, everything current
Balances, dues, and pantry — all at a glance. Nothing buried, nothing you have to dig for.
What it holds
A single, honest record of shared life
Shared money
Accounts, income, expenses, and transfers between household members — recorded plainly, split however you actually split things.
Dues, to anyone
Not just who owes who in the house. The shopkeeper you run a tab with, the friend who covered dinner — they're all just as easy to track.
Pantry stock
What's running low, what's just been restocked. The small, unglamorous coordination that actually keeps a household running.
Full history, one tap away
Every entry remembers who changed it and when. The home screen stays clean — the history is there when you need to check.
Nothing ever leaves your phones.
Kin has no servers, because a household ledger doesn't need one. Your data moves the same way you and your housemates do — from one room to the next, only when you're actually together.
A direct APK, not a store listing — same reason nothing else about Kin goes through a server.
