A free, all-in-one productivity app.
Getting organized in 2026 too often looks like this: a to-do list somewhere, a habits app elsewhere, a calendar in a third tool, and new-year objectives… in a spreadsheet nobody opens again. Each tool is fine, but none of them talk to each other.
Cosmo starts from a simple conviction: personal productivity rests on four pillars: tasks, habits, time and objectives, and they only really work when connected. A task gets scheduled in the calendar, a habit feeds an objective, and all of it is measured in one place.
All three refer to the same app: Cosmo, available at thecosmo.app. People also look for us as “Cosmo app”, “The Cosmo” or “thecosmo app”, it's always us. Not to be confused with other products of the same name on mobile stores: Cosmo is a web app, with nothing to download, and its only official site is thecosmo.app.
Cosmo is an independent product, built in France by a very small team: no funding round, no aggressive growth hacking, just a product we improve every week by listening to what users tell us.

Commencer gratuitementCosmo is a free, all-in-one productivity application built in France: tasks, habits, a calendar with time-blocking and OKRs connected in a single ecosystem. An independent product, developed in France.
Most organised people use three or four tools: a task manager, a habit tracker, a calendar, and a spreadsheet for the annual goals they reopen twice a year. Each does its job well, none sees the whole. The result is that underlying goals carry no weight against the urgency of the day, because they are not written anywhere you look every morning.
Cosmo came out of that observation. Bringing the four together in one product is not a convenience: it is what lets a quarterly goal come down into concrete tasks, a task receive a real slot in the calendar, and the statistics show the gap between what you are aiming at and what you actually do. None of those links is possible when the data lives in four separate applications.
All three refer to the same application: Cosmo, available at thecosmo.app. People also look for us as "Cosmo app", "The Cosmo" or "thecosmo app", and that is always us. Several unrelated products carry the name Cosmo (a German radio station, various mobile apps): Cosmo is a web productivity application, with nothing to download, and its only official site is thecosmo.app.
The project is developed by an independent team, in France. A question, a bug, a feature idea, a press request: write to contact@thecosmo.app, because user feedback genuinely steers the roadmap.
