Best Free Time-Tracking Software in 2026

Which Free Plan Fits Which Situation

Before the full breakdown, here's the quick version: if you're a small team of any size, Clockify is the only one of these four with no user cap on its free plan, which makes it the default pick for anyone past a one-person operation. If you're solo and want the cleanest interface with unlimited projects, Toggl Track's free plan (capped at 5 users, which doesn't matter if it's just you) is hard to beat for daily use. If you need client invoicing baked in and only track time for one or two clients at a time, Harvest's free plan covers that narrow case well. And if the actual problem is that you forget to track time in the first place, RescueTime solves a different problem entirely by tracking automatically in the background.

Clockify: The Only Truly Unlimited Free Plan

Clockify's free plan supports unlimited users, unlimited projects, and unlimited time tracking with no time limit on how long you can stay on it — a genuinely unusual offer in a category where "free" almost always means "free for one person." It includes a timer and manual time entry across web, desktop, and mobile apps, plus basic reporting and project tracking. The trade-off is that some features stay behind a paywall even for teams: billable rates, time approvals, and locked timesheets require the paid Basic tier at roughly $4.99/user/month, and GPS tracking or screenshots require the Pro tier above that.

Toggl Track: The Cleanest Interface, With a 5-User Ceiling

Toggl Track's free plan doesn't limit projects or clients, only the number of people on the account — up to 5 users at no cost, with unlimited projects, a one-click timer, and a browser extension that connects to over 100 other tools including Asana, Jira, Slack, GitHub, and Notion. For a freelancer or a small team of five or fewer, that's a genuinely full-featured free plan. The gap shows up once billing enters the picture: you can't set billable rates on the free tier, so everything tracked is just time, not money you can turn into an invoice. Project time estimates, saved reports, and time rounding are also paid-only, starting at $9/user/month on the Starter plan.

Toggl's reputation for interface quality is well earned — drag-to-create calendar entries and a visual project board make manual time entry noticeably less tedious than in most competitors, which matters if the reason you're not tracking time consistently is that the tool itself is annoying to use.

Harvest: Built-In Invoicing, But Only for One Person

Harvest's free plan is narrower than Clockify's or Toggl's by design — it's capped at 1 active user and 2 active projects, which makes it a fit only for a solo freelancer with a small, stable client roster rather than any kind of team. What you get within that limit is genuinely useful, though: a core timer, desktop and mobile apps, and basic invoicing that lets you turn tracked hours directly into a client-facing invoice without a separate tool. That combination — tracking and invoicing in one free plan — is something neither Clockify nor Toggl offers at the free tier.

The ceiling arrives fast if your freelance work grows past two active projects at once, at which point Harvest's paid plan runs around $11/user/month. Also worth knowing: the free plan can't upload a company logo, attach files to invoices, integrate with QuickBooks Online, or export invoices as PDFs, which matters if you want your invoices to look fully professional.

RescueTime: Automatic Tracking Instead of a Timer

RescueTime solves a different problem than the other three tools on this list. Instead of a timer you start and stop, it runs in the background and automatically records how you spend time across every app and website you use, then reports back on where the hours actually went. That makes it a poor fit for generating client invoices, since it's not organized around billable projects the way Clockify, Toggl, or Harvest are — but it's a genuinely better fit for a specific, common problem: not knowing where the day actually went, or catching how much time is quietly leaking into distraction versus focused work.

Its free tier (branded RescueTime Lite) covers the automatic tracking and basic reporting; deeper features like focus session blocking, detailed historical reports beyond a few months, and goal-setting sit behind the paid tier, priced roughly $7 to $16 per user per month depending on the plan.

How to Actually Decide

The fastest way to pick is to identify which specific limit you're most likely to hit first, since that's the one that actually determines your real cost. A team of six or more will hit Toggl's user cap immediately, making Clockify the obvious default. A freelancer juggling three or more active clients at once will outgrow Harvest's project cap fast, even solo. Someone who already knows what they're working on but keeps forgetting to start the timer has a workflow problem no manual timer solves — that's the case RescueTime is actually built for.

It's also worth thinking about where the tracked time needs to end up. If the goal is purely internal — understanding how long a task actually takes so future estimates get more accurate — any of Clockify, Toggl, or RescueTime will do the job without needing a paid plan at all. If the goal is turning tracked hours into something a client sees and pays against, that requirement narrows the field fast, since only Harvest bundles invoicing into its free tier, and even that comes with the 2-project ceiling. Teams that need both — multiple people tracking time and eventual client billing — will likely end up on a paid plan regardless of which free tool they start with, so it's worth treating the free tier as a trial of the interface and workflow rather than a permanent home if billing is on the roadmap.
