Google Tasks is one of the lesser known parts of Google Apps. In fact, it doesn't even have its own Wikipedia page. Arguably, Google Tasks best known feature is an ability to create a task directly from Gmail, though Google Tasks integration with Google Calendar comes handy too. When it comes to group work, Google Tasks may disappoint you, since it offers absolutely no social collaboration tools, nor offers time management, Gantt chart or other standard project management features. If you are looking for a free Google Tasks alternative, the one that comes with powerful project and client management capabilities, including CRM, quotes and invoices, available both in cloud and as self-hosted software with source code, consider Bitrix24. * Please note that the information may have changed since the publication.
