Spindle: Time Tracker

Spindle is a time tracker for people and teams who work on several things at once.

Most time trackers put each entry on a single project. When an AI agent works on one project while you start a task in another, that hour went into both. In Spindle, an entry can split its time between up to six projects, and every report counts each part on its own project.

On your iPhone:
• Start and stop the timer, with project, tags and billable time. The running timer stays on the Lock Screen and in the Dynamic Island.
• Start a timer with Siri or the Shortcuts app.
• See your day in a calendar and add time with a tap.
• Edit entries and their projects; entries split on the web or the Mac show each project's share.
• Reports with filters.
• Manage projects, clients and tags.
• Keep working offline: changes are sent when you're back online.
• Pomodoro, if you like working in focused blocks.

On the Mac, Spindle can suggest splits from the Claude Code and Codex logs on your computer. It keeps when you worked, never what you wrote, and nothing is saved until you confirm it.

Spindle doesn't watch your screen, apps or windows. In a team, each person confirms their own time.

Spindle is open source. You need a Spindle account to use the app.
