You track time so you can bill for it. Paying a monthly subscription for the privilege eats into exactly the hours you're tracking. Here's the free alternative.
One category per client. Set up categories for each client or project. Every logged block of time lands under the right client automatically, so there's no untangling at invoice time.
Track as you work, not from memory. Use the built-in focus timer while you're in a task. Reconstructing a week from memory at invoice time is where undercharging happens — studies of freelance billing consistently show unlogged time is simply lost income.
Export the evidence. At invoice time, export your log to CSV: dates, tasks, durations, per client. Attach it to the invoice or keep it as backup when a client asks what the 14 hours covered.
Most freelancers only track billable hours, which hides the real picture. If you bill 20 hours a week but spend another 10 on proposals, admin, and email, your effective rate is two-thirds of what you think it is. Tracking everything — billable and not — is how you find out whether to raise rates, cut admin, or drop the client whose "quick questions" consume your Tuesdays.
Being straight with you: if you invoice many clients monthly and want invoices generated automatically from tracked hours, Harvest earns its fee. If you collaborate inside a team's shared workspace, Toggl or Clockify make sense. One Day Tracker is for the freelancer who wants clean tracking and timesheets without another subscription on the books.
Create a category per client, log time against it through the day, and export the CSV at invoice time. The export lists tasks, dates and durations — the evidence behind your invoice line items.
Yes — the CSV is clean enough to attach to an invoice as-is, or paste into your own invoice template.
It works in any browser on both, but data is stored locally per device — it doesn't sync between them. Pick one primary tracking device (most freelancers use their work machine) for a single source of truth.
Free, no account, no subscription eating your margin.
