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€’ Forgot to start it? Add entries manually at any time β€’ Split an entry in two when one session covered two things β€’ Move an entry to another project if you picked the wrong one β€’ Mark work as billable or non-billable β€’ Stop or restart the timer from your iPhone Lock Screen or Home Screen β€’ Reminders on workdays if you haven't started the timer, and in the evening if it's still running CUSTOMERS & PROJECTS β€’ Store customers with address, email, phone and website β€’ Set a default hourly rate per customer and override it per project β€’ Give a project a budget and get warned before you run over it β€’ Internal projects without a customer, for your own work β€’ Archive finished projects without losing their history TASK TYPES Categorize your entries β€” design, development, meetings, research, admin, or whatever fits your business. DASHBOARD Today at a glance: hours logged, every entry in order, the running timer always at the top β€” and what's unbilled, invoiced this month and still owed to you. REPORTS β€’ Group by project or by customer β€’ Switch between hours and billable value β€’ Chart view or list view β€’ Last 7 days, last 30 days, last month, everything, or a custom date range INVOICES β€’ Turn a customer's unbilled hours into a PDF invoice in a few taps β€’ Set up your business details, bank account, VAT ID and numbering 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, in your own words or ready-written, or share and save the PDF β€’ Optional rounding for billing, e.g. to 15 minutes, without changing your tracked time β€’ An issued invoice never changes; its hours are protected until you void it GET PAID β€’ See at a glance which invoices are open, overdue or paid β€’ Mark an invoice as paid with the date the money arrived β€’ Filter by date, customer and status, and see what's still outstanding CSV EXPORT Prefer your own invoicing software? Export any date range to CSV β€” customer, project, start, end, duration, amount and description. ON THE MAC Hour Ledger lives in the menu bar. Start and stop the timer without leaving the app you're working in, and see at a glance whether the clock is running. Step away while the timer 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, with iCloud keeping everything in sync. Prefer to keep things local? Turn iCloud sync off in Settings and your data stays on the device. PRIVACY BY DESIGN Hour Ledger collects nothing. No analytics, no trackers, no ads, no developer servers.

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.
