ClockOn Time Tracker

ClockOn is a time tracker for freelancers who work across multiple clients and need a clear, dependable way to track billable hours.

It’s ideal if you want a simple time tracking app without subscriptions, accounts, or cloud sync.

No login. No ads. Works fully offline.

Built for real freelance work
ClockOn keeps things simple:
• Create separate accounts for each client
• Switch between accounts with a single tap (in-app)
• Start and stop tracking instantly
• Enter time manually when needed
• Edit past entries easily
• Export as CSV for invoicing
It’s designed around how freelancers actually work — not around project management trends.

Clear weekly totals
See exactly how many hours you’ve worked this week for each client.
Switch between accounts to view clear weekly totals, so you always know where your time has gone.
Weekly summaries help you:
• Review billable hours
• Stay organised
• Prepare invoices
• Keep control of your workload
No clutter. Just clear numbers.

Fully offline and private
ClockOn:
• Requires no login
• Stores all data locally on your device (until export)
• Uses no network after installation (except export)
• Requests no special permissions
Your work data stays yours.

Quick access with a home screen widget
Track time quickly from your home screen:
• Select an account
• Clock on
• Clock off
(For instant account switching while already clocked on, use the in-app one-tap switch.)

Early release
ClockOn is currently free while it continues to develop.
Multi-client support will eventually become part of a Pro upgrade. Early users will always be treated fairly.

Who ClockOn is for
ClockOn works best for:
• Freelance developers
• Consultants
• Contractors
• Designers
• Independent professionals billing multiple clients
If you’re looking for a full project management suite or team collaboration platform, ClockOn intentionally keeps things simpler than that.
It’s built to do one job well:
Help independent professionals track and bill for their time clearly and reliably.
