What it does

See where the time went

The timeline shows each day at a glance, and Analysis compares periods with metrics such as total time, focus ratio, weekly targets, earnings and time per project.

Analysis cards for total time, active days, average per active day, earnings, fixed fee and weekly target, with changes compared with the previous period.

Know what each project takes

Project breakdowns show each project's share of your time, how projects rank against the previous period, and how they trend across the days.

Work out what to bill

What makes it different

Private by design

No account, no telemetry and no network calls from the app.

Your files, your cloud

It uses your own OneDrive or Google Drive folder rather than a company's server.

Corrections leave a trail

Every change is written to the history, so a figure can be explained later.

Exact and billable time, kept apart

You always see what really happened and what you can bill.

Built for working across time zones

Times are stored in UTC and shown in your zone, your client's zone or any other, including across daylight saving changes.

Notices

Please read before you install

  • Uninstalling removes local data

    Windows removes this app's local data on uninstall. Connect a OneDrive or Google Drive folder to keep a permanent copy.

  • One device at a time

    The app is built for one person on one device at a time. Sync carries your work between devices, but doesn't make it safe to edit on two at once.

  • Sync files aren't encrypted by the app

    Files in your sync folder hold your full labor data, including prices. They are protected only by your OneDrive or Google Drive account.

  • Not an invoice or tax tool

    Billing summaries and figures are for guidance only, and aren't invoices, accounting or tax advice. Check them before you bill a client.

Cloud sync needs the provider's app. OneDrive or Google Drive desktop must be installed and signed in. Those services have their own terms and are not part of this app.

WebView2. The app needs the Microsoft Edge WebView2 Runtime. Windows 11 includes it, and some Windows 10 PCs may need to install it.
