About

WorkClock Journal

Read full description

WorkClock makes day-based time tracking effortless, with dynamic break calculation and clean CSV/PDF exports. No account, no location, your data stays on-device. Why WorkClock? Most trackers apply rules per session. WorkClock computes breaks at the day level : reliable, transparent, and aligned with real-life workflows. How it works 1 session with no explicit break → recommended break (adaptive) or fixed break per your settings. ≥ 2 sessions: if no explicit break exists, WorkClock computes the gap (elapsed time − worked time). Rounding is applied at the day level (not per session). You stay in control: everything is editable before export. Key sections Today: start/stop, live counter, day list, “Break … (suggested)” when relevant. Week: per-day summary, weekly totals. Month: totals & averages (hours/day, break/day), month weeks, exports. Exports: CSV and PDF (header totals + table). Settings: reset sessions, optional reset total, inject sample data (with confirmation), break modes (fixed / adaptive). Privacy & tech Local data with SwiftData. No location. No account, no tracking. Who is it for? Consultants, freelancers, trades, field teams, HR/time admins—anyone who wants a clear, day-first timesheet without friction.
