OneApp Finance is a free set of utilities for iOS, iPadOS and Mac that replaces a dozen single-purpose apps with one interface.
It includes a tax and tip calculator built on current 2025-2026 US sales tax rates, a fast unit and currency converter, a unified money tracker for debts, loans and expenses, and a notes module.
