Features
Everything you need, nothing you don't
Klok does the boring parts of freelancing — tracking, tagging, billing — so you can spend your hours on the craft clients actually pay for.
Clients & projects, sorted
Tag every entry to a client, project, and billable rate. Klok keeps your hours organised so month-end never feels like detective work.
Invoices in one click
Turn a week of tracked time into a branded, itemised invoice — with your rates applied automatically. Send it before the coffee cools.
Know your real rate
See effective hourly earnings per client and project, so you can spot the work that pays and the work that quietly doesn't.
Everywhere you design
Mac, Windows, web, and mobile stay in perfect sync. Start a timer on your laptop, stop it from your phone on the way out.
Your data, yours alone
No selling, no training on your work. Export everything as CSV or PDF anytime — your time logs belong to you, not us.
How it works
From blank canvas to paid in three steps
No setup weekend, no manual. Most designers track their first billable hour within two minutes of signing up.
- 01
Start a timer
Press ⌥K or click once. Klok captures the moment you start, so you never round away billable minutes again.

Tag as you go
Drop each entry onto a client and project. Rates apply automatically, and everything files itself in the background.
- 03
Bill in a click
At month-end, hit Invoice. Klok totals your hours, applies your rates, and hands you a polished PDF ready to send.

Testimonials
Designers stopped dreading the admin
A few words from the freelancers and studios who let Klok handle the clock.
I used to lose an afternoon every month reconstructing my hours from memory. Now Klok hands me an invoice that's already done. It paid for a year in the first week.
Lena Hartmann
Brand designer · Møller Studio
The effective-rate view was a gut punch in the best way — I finally saw which clients were worth it. I raised two rates and dropped one. Best business decision of my year.
Darius Okonkwo
Freelance product designer
⌥K is muscle memory now. I track without thinking about tracking, which is the whole point. It just sits quietly until I need the numbers.

Do I need a credit card to start?
No. The Solo plan is free forever, and every paid plan starts with a 14-day trial that needs no card. You only enter billing details if you decide to keep a paid plan.
Can I track time offline?
Yes. The desktop and mobile apps keep tracking when you lose connection and sync automatically the moment you're back online — so a flaky café Wi-Fi never costs you billable minutes.
How do invoices work?
Klok totals your tagged hours, applies each client's rate, and generates a branded PDF you can download or send. You can edit line items, add expenses, and set your own logo and colours before sending.
What happens to my data if I cancel?
It stays yours. Export everything as CSV or PDF at any time, on any plan. If you cancel, your account drops to the free Solo plan — we never delete your history out from under you.
Can I use Klok with my team?
Yes — the Collective plan adds up to five seats with shared projects, rates, and team utilisation reports. Need more than five? Reach out and we'll sort a custom plan.
Which platforms are supported?
Klok runs on macOS, Windows, the web, iOS, and Android, all kept in sync in real time. Start a timer on your laptop and stop it from your phone — it's the same session.
Stop guessing your hours. Start billing them.
Join 3,000+ freelance designers who let Klok handle the clock — and got their evenings back.
