Autasker

Autasker is a task manager from Vadim Erenkov. Its stated scope is narrow: entering things that need doing, working through them, and marking them off, without the milestones, dependency graphs and reporting layers that project-management suites add. The publisher's own summary positions it as simple but robust, which places it in the personal to-do list category rather than the team-coordination one.

The publisher describes Autasker as running on Android, Windows and Linux. The package recorded in this entry is the Android build, so if you want the desktop versions you will need to obtain them through the project's own distribution channels, which fall outside this listing. Anyone planning to keep one task list in sync across a phone and a laptop should check what the project offers on that front before committing.

The licence is GPL-3.0-or-later, so the source can be read, modified and redistributed under the same terms. That matters if you want to change how tasks are modelled, or to keep building the application yourself if upstream development stops.
