Fatto

Fatto is an Android companion for Taskwarrior, intended for people who manage tasks with the Taskwarrior model and want access from a phone or tablet. It presents task data in a mobile interface so that items can be reviewed and edited away from a desktop terminal. The application is published by brokenpip3 under the GPL-3.0-only license.

Its scope is tied to Android and to Taskwarrior-style task management rather than being a general calendar or project management suite. It is most relevant when a user already organizes work as tasks with descriptions, status, and related metadata, and wants a handheld client for viewing and maintaining that list.
