For freelancers
Time tracking built for freelancers, not managers.
You bill by the hour. You shouldn’t lose an hour a week fighting your tracker. Clessira sits in your Mac menu bar, remembers what you were doing, and hands you a clean timesheet at the end of the week.
Bill every hour you actually worked
Freelance work is spiky. A call here, a fix there, three context switches before lunch. The hours you forget to write down are the hours you don’t get paid for.
Clessira watches for idle time and asks what you were doing when you step away — so the gaps get filled while you still remember. No stopwatch to forget to start.
- Adaptive idle prompts catch the work you’d otherwise forget
- Group hours by client or project
- See the whole day as a colour-coded timeline
Turn tracked time into an invoice-ready timesheet
Every entry exports to CSV — client, activity, duration, date. Drop it into your invoicing tool, your spreadsheet, or your accountant’s inbox.
Need a specific format? Write a small JavaScript export script and Clessira shapes the output to match. Your timesheet, your columns.
- Clean CSV export for any billing workflow
- Custom JavaScript export scripts for exact formats
- Paste Jira issues, Markdown or tables straight into activities
Client data that never leaves your Mac
Freelancers sit on other people’s confidential work. Clessira keeps every entry in a local file on your Mac. No account, no cloud upload, no telemetry.
Choose where the file lives — local disk, iCloud, OneDrive, a NAS. Optional private iCloud sync keeps an iPhone, iPad and Watch companion in step, over your own iCloud. Made in Germany, GDPR-compliant by design.
- Data lives on your Mac, not on our server
- Free storage location: local, iCloud, OneDrive or NAS
- Optional private iCloud sync to iPhone, iPad and Watch

Is Clessira really free?
It is free on the App Store. If it ever becomes paid, it will be a one-time purchase — never a subscription.
Can I track multiple clients?
Yes. Organise activities into groups per client or project, and the reports and CSV export break the time down the same way.
Where is my time data stored?
In a local file on your Mac that you control. There is no account and no server. Keep it on local disk, iCloud, OneDrive or a NAS.
Can I get my hours into my invoicing tool?
Export to CSV for any tool, or write a small JavaScript export script to match a specific format exactly.
