ManicTime is a freelance time tracker that captures your work automatically in the background — so when it is time to invoice, you have an accurate record of every billable hour spent on every client, without ever starting a timer.
Most freelancers start by looking for a simple time tracking app that can track billable hours, client work, and admin time without turning the day into stopwatch management. The problem is that manual timers break down fast once you juggle multiple clients, revisions, and short task switches.
A quick email here, a short revision there — small blocks of billable time disappear when there is no automatic record. By invoice day, those hours are gone.
When you switch between three clients in one afternoon, remembering which work belonged to whom becomes unreliable. Guessing at invoice time means either undercharging or over-explaining.
Starting and stopping a timer every time you switch tasks is disruptive. Most freelancers stop bothering — and end up estimating at the end of the week.
The third round of feedback on a fixed-price project often takes as long as the original work. Without a record, that extra time gets absorbed rather than documented and discussed.
Freelancers who track inconsistently spend an hour at month-end trying to piece together what they did and when — time that could go toward billable work.
Most freelancers try timer-based tools first and abandon them within weeks. Starting and stopping a timer for every context switch is incompatible with focused work — and knowledge workers switch tasks dozens of times per day. Manual tracking captures a fraction of what actually happens.
Automatic tracking takes a different approach: record everything first, then categorize. ManicTime runs silently in the background and builds a complete timeline of your workday — applications, documents, websites, and idle time — without any input from you. At the end of the day or week, you review what was captured, assign it to clients and projects, and invoice from that record.
The result is a billing history that reflects what actually happened, not what you remembered to clock.
ManicTime records your full workday automatically. Every app, document, and website is logged with timestamps — so no billable time slips through because you forgot to start a clock.
ManicTime captures document names and paths, not just application names. If you had three client documents open in the same app across the day, each gets its own time record.
Review the day's captured activity and assign blocks to the right client or project. Auto-tagging rules can do this automatically if your files or folders follow a consistent naming pattern.
Once time is reviewed and attributed, generate a client-ready invoice from that data in ManicTime — no re-entry into a separate tool, no arithmetic from memory.
Off-the-record mode and tracking schedules let you define exactly when ManicTime records and what it captures — so personal browsing and non-work time stays private.
Freelancers work across many tools and contexts. ManicTime captures all of it:
Every block is timestamped and attributable — so month-end invoicing becomes a review, not a reconstruction.
If you are comparing freelancer time tracking apps, the real question is whether the tool can recover missed billable hours, make invoicing easier, and stay out of your way while you work. ManicTime is built around that workflow.
Automatic tracking captures every work session including short ones, late-day revisions, and quick client emails that manual timers always miss.
File-level document tracking and project tagging give you a clean split of time across clients — even on days when you switched between three projects before lunch.
Going from tracked time to a sent invoice takes one review step in ManicTime. No spreadsheet, no re-entry, no end-of-month guesswork.
Revision rounds and extra requests are recorded automatically — giving you the data to have informed conversations about additional time rather than absorbing the cost.
You decide what gets tracked, when tracking runs, and what is shared. Personal time on a work machine stays yours.
Capture every hour of client work without timers, interruptions, or manual entries.

Learn more ->ManicTime has been tracking time since 2008. Over 1 million downloads, 13,000+ customers, and 200,000+ licenses later, it is still the tool freelancers reach for when accurate billing actually matters. That kind of track record means the product is not going anywhere — and the billing workflow you build around it will still work next year.
Freelancers lose revenue in small increments — a 20-minute revision here, a client email there, a feedback round that turned into two hours. None of it gets invoiced because none of it was tracked. ManicTime solves this by capturing everything automatically, so the record exists whether or not you remembered to start a timer.
Document-level tracking means multi-client days stay clean. Time on a Photoshop file for one client is separate from time on a document for another, even if both were open in the same application. That detail makes invoices accurate and defensible.
The main alternative freelancers consider is a timer app like Toggl or Harvest. Those tools work if you track consistently — but consistency is the hard part. ManicTime's approach is different: capture everything automatically, then decide what to bill. A bad week where you forgot to track doesn't cost you revenue, because the record was built whether or not you remembered to start anything.
