Ask yourself how long the last report took you to write. Now check your calendar and the file’s edit history. If the real answer is longer than your guess, you’re in good company.
That gap has a name, the planning fallacy, and it’s the best reason to track your time. You’re not doing it to be monitored. You’re doing it to find out how long things actually take, so your next plan is based on evidence rather than optimism.
This guide compares four time tracking apps by what their free plans include and what the paid plans cost, using each company’s pricing page on 18 October 2026. Prices change, so the date matters.
Quick answer: For a small team on a budget, Clockify’s free plan allows up to 5 users and includes unlimited tracking. For a freelancer who invoices clients, Harvest’s free plan (1 seat, 2 projects) includes invoicing. Toggl Track has a free plan for small teams, with paid plans from $9 per user per month billed annually. RescueTime is the one to look at if you’d rather not start timers yourself, but check what its free plan includes first.
Why track time at all?
People tend to underestimate how long their tasks will take, even when they know similar tasks ran late in the past. Researchers call this the planning fallacy. It shows up for small tasks like chores and for huge projects, across personality types and cultures. Conscientious people finish earlier than procrastinators, but both groups underestimate (Buehler, Griffin & Ross, 1994, summarised by the Society for Personality and Social Psychology).
The remedy researchers describe is the “outside view”: compare your task with similar past ones and how long they took. A time tracker is a way to build that history. Two weeks of tracking gives you your own numbers, such as “client emails take me 40 minutes a day” or “first drafts take twice what I plan.”

Which one should you pick?
Freelancer who bills by the hour: Harvest or Toggl Track. Harvest’s free plan includes invoicing, though it’s limited to one seat and two projects. Toggl’s billable rates start on its Starter plan.
Small team on a tight budget: Clockify. Up to five users on the free plan is the most generous limit here. Extras like invoicing and approvals are paid, from Standard at $5.49 per seat per month billed annually.
Solo, just trying to understand your day: any free plan. Pick the one with the app you’ll actually open. You don’t need billing features to answer “where did my week go?”
Manual versus automatic. A manual timer is accurate but easy to forget. Clockify lists an auto tracker among its free features. RescueTime is built around the idea of tracking without you starting a timer, though its pricing page doesn’t say what the free plan covers, so test it before relying on it.
How to get real insight from a time tracker
These steps are our suggestions, not research findings.
- Track for two weeks before you change anything. You need a baseline.
- Use few categories. Five to eight is plenty (“meetings,” “deep work,” “admin,” “email”). More than that and you’ll stop labelling.
- Compare your guess with the result. Before a task, write your estimate. Afterwards, check the tracker. Do this for a few task types.
- Plan with your own numbers. If reports always take twice your estimate, double it. This is the outside view in practice.
- Pair it with time blocking. Once you know how long things take, block that time on your calendar. See our guides to time blocking for entrepreneurs and time auditing.
Frequently asked questions
What is the best free time tracking app? For teams, Clockify, whose free plan allows up to five users. For freelancers who invoice, Harvest’s free plan includes invoicing for one seat and two projects.
Is time tracking worth it if I’m not billing clients? Yes, for the planning fallacy reason above. A couple of weeks of data shows how long your tasks really take, which makes your plans more realistic.
How long should I track my time? Two weeks gives a reasonable baseline, and it’s long enough to include a few different kinds of days. That’s our suggestion, not a research finding.
Do I need a different app for tracking time and blocking distractions? They’re different jobs. For focus timers, see our guide to free Pomodoro timer apps.
