Tracking time

Every card gets a Worklog section: a timer, a quick form for manual entries, an estimate and the list of everyone's entries on the card.

Timer

Press Timer and work. The timer runs on our server, so it keeps going if you close the card, the tab or the browser.

Lost track of a timer? The Tacto button on the board → Running timers lists every running and paused timer on the board, plus your timers on other boards. A timer running for more than 8 hours is highlighted in this list, and its badge on the card turns red.

Manual entries

Fill in the form at the top of the Worklog: date, time spent and an optional comment, then press Log time. An entry for today ends now: 2h at 16:20 is work from 14:20 to 16:20.

A number without a unit means hours, up to a working day: for 45 Tacto asks you to write 45h or 45m.

Full form

Editing and deleting

The ✏️ icon next to your entry edits it, 🗑 deletes it after a confirmation. You can change only your own entries; colleagues' entries are read-only for you. Every edit and deletion goes to History, and a deleted entry can be restored for 30 days.

Estimates

Press Set an estimate under the total and enter a plan such as 8h — that's the estimate for the whole card. To split it, press + Add work type and fill in rows: “Design 12h”, “Frontend 20h”, “QA 8h”; the total is their sum. Once set, the Estimate block sits at the top of the Worklog and shows only the plan; time spent against it is in the progress bar of the full form, and per work type in reports. Anyone on the team can set and change an estimate; changes show in History.

A card estimate split by work type

When you log time you can pick a work type — what the time went into. The field appears when the card's estimate is split by work type and defaults to “No work type”, so time never lands on someone else's estimate by accident. Entries without a work type are shown separately.

Board guests (a client, for example) see only the Estimate block on a card, when there is one — no worklog, timer or entries. To compare estimates with actual time across all cards, open Reports → Analytics → Plan vs actual.

Board badges

Cards with tracked time show a clock badge with the total right on the board. While someone is tracking a card, a second badge shows who is working or paused — stand-ups get shorter. It turns red if a timer has been running for more than 8 hours.

How entries are shown

Entries are grouped by day — Today, Yesterday, then dates — with totals for the day and the week. Under the form you can see each member's share of the card's time. A long worklog loads in portions with Show more.
