Why One Platform
Stop Paying for Two Tools
Freelancers typically pay $9–18/mo for time tracking plus $15–30/mo for invoicing. We give you both in one product — deeply integrated, not bolted on.
Save $300+/Year
No separate time tracking subscription. Invoicing and time tracking are included together in every plan, including free.
Included on all plans, even Free

Your Time, Beautifully Organized
A clean dashboard shows tracked hours, billable value, active timers, and unbilled time at a glance — grouped by day with color-coded entries.
Multiple Input Modes
Track Time Your Way
Whether you prefer clicking a timer, typing hours manually, speaking naturally, or letting AI handle it — we support every workflow.
One-Click Timer
Start and stop a live timer with a single click. It persists across page navigations, survives browser refreshes, and works offline. Idle detection prompts you when you have been away.
Manual & Quick Entry
Type "2h acme api" into the quick entry bar and the AI instantly creates a time entry — no forms, no dropdowns. Or use the full form for precise start/end times.
Voice Input
Tap the microphone and say "I spent 2 hours on the Acme website redesign yesterday afternoon." The AI parses duration, client, date, and description automatically.
AI Suggestions
The AI learns your patterns and suggests time entries from your calendar events, recurring work habits, and detected gaps. Just confirm what it finds.
Calendar Integration
Connect Any Calendar
Import events from Google Calendar, Microsoft Outlook, Apple Calendar, or any calendar that supports the iCal standard. Events become suggested time entries you can confirm with one click.

Google Calendar

AI Intelligence
AI That Catches What You Miss
