Description by Mesut Altuncu Written by the developer, not by AppBrain. Click to read.
Costbook is a simple, good-looking expense tracker. Log what you spend in seconds, set budgets and see where your money goes: your monthly spending, a trip, a wedding or any project.

When costs are shared, invite others to a list and Costbook works out who owes whom. Friends join for free.

TRACK YOUR SPENDING

• Separate lists for every budget: monthly spending, trips, events, projects
• Set a budget for each list and see what's left
• Charts by category, payment method and person
• Search every expense across all your lists

SCAN INSTEAD OF TYPING
• Scan a receipt or bill and let AI fill in the amount, merchant, category and date
• Keep receipt photos with every expense

SHARE WHEN YOU NEED TO
• Invite others with a link or QR code; they join for free
• See who owes whom at a glance and record payments
• Get notified when someone adds an expense
