List the user's activity types as a tree (groups contain children): names plus internal ids. Use the names when talking to the user; use the ids for exact targeting in other tools.

Show currently running or paused activities with elapsed time.

Start tracking an activity by type name (fuzzy matched, see list_activity_types) or type_id. Optionally backdate the start with at (wall-clock) or started_minutes_ago.

Stop a running or paused activity. type_name may be omitted when exactly one activity is active. Optionally backdate the stop with at (wall-clock) or stopped_minutes_ago.

Pause a running activity or resume a paused one.

Retroactively log a completed time entry for an activity type. Times are wall-clock in the user's timezone, format "yyyy-MM-dd HH:mm".

Update the comment and/or tags of an existing entry (running, paused, or stopped) without changing its tracked time. Use this instead of logging a new entry when the user wants to annotate, describe, or re-tag something already tracked. Get activity_id from get_current_status (active timers) or list_intervals (past entries).

Aggregated time statistics per activity type for a date range. Returns overall totals plus per-DAY/WEEK/MONTH buckets.

List raw time entries (intervals) grouped by day for a date range (max 100 days). Paged by day — use page for older days.

Official ATimeLogger app documentation. Use it to answer any question about how the app works, or how to do in the app what these tools cannot (edit entry times, delete records, goals, widgets, CSV export, sync, backups, Pomodoro, Premium features). Call with no arguments for the table of contents (its note covers platform applicability), then again with topics to fetch the relevant pages — answer from the docs, not from memory. Cross-references like sync.md inside a page point to the topic with that slug.
