Super Productivity

Super Productivity merges to-dos with time tracking in a way freelancers appreciate: track time per task, get worklogs and summaries for invoicing, pull issues from Jira, GitHub, GitLab, and more into your day, and structure focus with Pomodoro and break reminders. Data stays local with optional sync via WebDAV/Dropbox, and it’s fully open source.

It’s an Electron app with the usual footprint, and the abundance of features makes the settings a maze — it rewards configuration effort and punishes casual use. No official mobile experience worth relying on, so it suits people whose work happens at a desk. If you just need a grocery list, this is overkill.
