# TimeTagger

> Open-source time tracker built on tags and a timeline

TimeTagger is an open-source time tracker for individuals and freelancers, built by a one-person Dutch company. Records live on an interactive timeline and are organized with tags written into their descriptions rather than with projects. A report dialog turns any period into a PDF or CSV. It runs as a web app that can be installed on phones and desktops, either on the paid hosted service or on a server of your own.

## Ways to pay less

- **Lifetime plan for €144** (Lifetime license): The pricing section offers a Lifetime plan at €144, paid once, with the same service as the basic subscription. Source: https://timetagger.app/
- **€1 a month less with annual billing** (Annual discount): The basic plan is €3 a month when billed annually, the default. Monthly billing costs €1 more a month, which the vendor attributes to transaction costs. Source: https://timetagger.app/

## Key features

- **Interactive timeline:** Records sit on a timeline that scrolls and zooms from a day to longer ranges. A record is created by dragging on the timeline and edited by dragging its start, its end or the whole block.
- **Tags instead of projects:** Any word in a description that starts with # becomes a tag. Tags exist only through the records that use them, can be renamed in bulk, and filter the overview into a breakdown.
- **PDF and CSV reports:** The report button builds a table for the selected period and tags. It saves as a PDF for billing clients or as CSV with durations in decimal hours for a spreadsheet.
- **Targets and Pomodoro:** Targets can be set and progress followed against them, and a built-in Pomodoro mode structures work into focused sessions.
- **Installable and usable offline:** TimeTagger is a progressive web app: it installs from the browser on Android, iOS and desktop, keeps working without a connection and syncs changes when back online.
- **Web API and command line:** A documented web API and a separate CLI tool let records be read and timers started from scripts or a terminal. The source is on GitHub and can be run locally or self-hosted.

## Good for

- Freelancers who want a low-cost tracker and PDF reports for clients
- People who prefer tagging entries to setting up projects
- Developers who want to self-host their time data or script it through an API

## Worth knowing

- It is not in the App Store or Google Play; on phones it is installed as a web app from the browser.
- The hosted service has no free tier, and after a subscription lapses the app becomes read-only, though data can still be exported.
- Prices are set in euros; the vendor says buyers in most countries pay in their local currency.
- It is aimed at individuals: buying several subscriptions for a team is arranged by email.
