Support Efflow

Efflow is a timeline-first day planner — calendar, tasks, notes and time tracking on one page — built and maintained by one person. Donations go straight into keeping it running: servers, the database, domain and the hours that go into new features and fixes.

Giving is entirely optional and changes nothing about your account. Efflow works the same whether you donate or not.

Before you give

No. There are no perks, no badges and nothing changes in the app. A donation is purely voluntary support for the work — every feature behaves exactly the same before and after.

Thank you — genuinely. Efflow is a small project, and every contribution buys it more time.
