OpenTasks review
A free Android task manager with recurring tasks, widgets, and open data access.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenTasks is a free, open-source task-management application for Android. It organizes to-do items through the iCalendar VTODO data model, with task lists, due dates, time-based task handling, recurring tasks, notifications, checklist items, and widgets. The app is suited to solo users and small teams who want a focused mobile task manager and prefer task data that can be accessed by permitted third-party applications. Its Apache 2.0 license also makes the project suitable for users who value open-source software.
The main fit question is synchronization. OpenTasks does not provide built-in task synchronization or calendar support, so users who need those capabilities must connect it with external applications. It integrates with aCalendar+ and CalDAV synchronization apps, while third-party access to task data is available with permission. That approach suits Android users who already have a compatible synchronization setup, but it is less suitable for anyone seeking an all-in-one task and calendar service. The VTODO model gives the app an open data foundation, though the broader experience depends on the surrounding apps.
Pricing is straightforward: the Free plan provides open-source task management for Android under the Apache 2.0 license. There are no paid tiers described, and no trial card is required. OpenTasks covers core personal task workflows without a subscription, including recurrence, reminders, checklists, and widgets. Its support channels are phone and ticket, while the listed GitHub release is version 1.4.2 from 2021. Choose OpenTasks if Android support, free access, recurring tasks, and external synchronization options matter most. Choose another tool if you need built-in calendar synchronization, broader platform coverage, or a more self-contained ecosystem.
