Tempo — Time Tracking & Billing — a premium, 100% offline digital tool by Aceplore. Runs entirely in your browser: no accounts, no subscriptions, your data never leaves your device.

A private, offline time tracker that turns hours into income — a live timer, weekly timesheets, project budgets, utilization and invoice-ready billable time — 30 tools in one, with your data never leaving your device.

30 built-in tools in one app — a genuinely deep, professional-grade workspace, not a single calculator. A dashboard of weekly hours, billable vs non-billable, revenue and utilization; a live start/stop timer and a weekly timesheet grid; all time entries; projects with rates, budget hours and burn; per-project detail with revenue; tasks and clients with rates; a time calendar; billable breakdowns, rate management, budget-vs-actual and utilization vs capacity; revenue by client/project, unbilled time and an invoice-prep draft with expenses; estimated-vs-actual hours, productivity by day and hour, overtime alerts and goals; a timer-session log, rounding rules, approval status and period summaries; plus trends, export (CSV) and settings.
