Read full descriptionHide full description
Hour Ledger is the time tracker and invoicing app for freelancers, consultants, agencies and everyone who bills by the hour. Start the timer when you begin, stop it when you're done β and at the end of the month you know exactly what you worked on, for whom, and what it's worth. A few taps later it's an invoice. No account, no subscription, no ads. TRACK TIME THE WAY YOU WORK β’ One tap starts the timer on the project you're working on β’ Or say "Start Website in Hour Ledger": Siri, Shortcuts and Control Center start and stop it too β’ The running timer on the Lock Screen and in the Dynamic Island, with a stop button β’ Lock Screen and Home Screen widgets, pinned to a project if you like β’ Forgot to start it? Add entries by hand, split them or move them to another project β’ Mark work as billable or non-billable β’ Reminders on workdays if you haven't started the timer, and in the evening if it's still running CUSTOMERS & PROJECTS β’ Customers with address, email, phone and website β their projects and invoices in one place β’ A default hourly rate per customer, overridden per project if needed β’ Project budgets, with a notification when one runs low or is used up β’ Internal projects for your own work, and task types with their own icons DASHBOARD Today at a glance: hours logged, every entry in order, the running timer at the top β and what's unbilled, invoiced this month and still owed to you. REPORTS β’ Group by project or customer, in hours or billable value, as a chart or a list β’ Last 7 or 30 days, last month, everything, or your own date range β’ Export a time report as PDF or Markdown, or every entry as CSV INVOICES β’ Turn a customer's unbilled hours into a PDF invoice in a few taps β’ Add flat fees, travel and expenses alongside the hours β’ Business details, bank account, VAT ID and numbering, set up once β’ VAT handled for you: standard rate, a custom rate per customer, reverse charge, or VAT-exempt with your own note β’ Invoice numbers continue automatically, per year if you like β’ Send the invoice by email with the PDF attached, or share and save it β’ Optional billing rounding, e.g. to 15 minutes, without changing your tracked time β’ An issued invoice never changes; take one back with a proper credit note β’ At year end, one ZIP with every invoice and credit note plus a list for your tax adviser GET PAID β’ See which invoices are open, overdue or paid, and what's still outstanding β’ Mark an invoice as paid with the date the money arrived β’ Filter by date, customer and status ON THE MAC Hour Ledger lives in the menu bar. Start and stop the timer without leaving the app you're working in. Step away while it runs, and when you're back Hour Ledger asks whether to keep that time, discard it or split it off. IPHONE, IPAD AND MAC A native app on every platform, kept in sync by iCloud β or turn sync off and your data stays on the device. PRIVACY BY DESIGN Hour Ledger collects nothing: no analytics, no trackers, no ads, no developer servers. Your data lives on your device and in your own iCloud account. MADE FOR HOW YOU BILL Pick your currency and app language (English, German, French, Spanish) in Settings β invoices are written in the language you choose. Buy it once. Track your hours. Get paid for all of them.
