Concrete Costs

Concrete Costs is a simple, offline expense tracker for construction projects. It works the moment you open it — no account, no sign-up and no internet connection required. Everything you enter stays on your phone.

Log every cost as it happens — materials, labour, equipment, transport, permits — and group it by project. Set an optional budget per project and Concrete Costs shows you, at a glance, how much you have spent and how much is left.

Keep a running materials inventory too. Add materials like cement, steel and bricks with their unit cost, track stock in and out, and see the value of everything on hand. When you record a materials expense, you can draw it straight from inventory so your stock stays accurate.

When you need your records elsewhere, export your expenses as a CSV spreadsheet or save a full backup file — then open that backup in Concrete Costs on another phone to see the same data. Your records, your device, your control.
