Böl

Böl (Azerbaijani for “split”) is an app for calm, transparent shared-expense tracking. You log what you paid, choose who it was for, and Böl calculates who owes whom, so households, trips and recurring costs stop living in spreadsheets and group chats.

One balance across every group

The home screen answers the first question people have: overall, am I owed or do I owe? Below that, each group (a trip, a flat, a dinner club) shows its own balance at a glance. People join a group by link, QR code or name.

Clear next steps for settling up

Inside a group, the balance card shows what you're owed, the group's total spend and your share of it. The settle-up view turns balances into concrete next steps: who pays whom and how much, with a reminder button and a way to mark a payment as received. Reminders are limited to one per day so nobody gets nagged.

Böl never holds or moves money. People settle in cash or by transfer through the methods they already use, and the app only records who owes whom.

Split it any way

Expenses can be split equally, by exact amounts, by percentage or by shares. When an amount doesn't divide evenly, the leftover cents go to the first people in the split, so totals always add up. Receipts can be scanned and expenses dictated by voice: Böl drafts the split and the user confirms it.

Built for iPhone and iPad

The layout adapts from iPhone to iPad, where groups sit in a wider grid alongside the balance summary. Groups can use multiple currencies, and Face ID protection stays on the device.

Product model

The free tier covers two active groups. Böl+ adds unlimited groups, receipts, custom categories, spending insights and priority support.

Böl is coming soon to the App Store. Learn more at split-bol.app.
