Crazy but there are more than a hundred of task management tools on the market. Even more crazy we didn't find a right one for our team after trying/using a dozen of them.

With list-based tools, our tasks grew into a unmanageable long list. We kept losing important-but-less-emergent tasks until we searched hard for them. The board-based tools can't manage a lot of tasks well either. It is good for daily or weekly tasks, but many tasks in our project can take long to get done. Smartsheet is good at managing hierarchical list but too complicated to me -- probably because we don't need the resource planning and I'm not a spreadsheet guy.

Quire did a great job for managing the complicated hierarchical task tree with a super friendly UI. I really appreciate the way we can break down a big task into several manageable tasks. It works like a charm when we started rolling out our project, inviting colleagues and breaking down tasks.

The gantt chart is locked behind their paywall, so there's really no point in using this program when others like todoist exist.

Allows offline use for free, unlike many

It was amazing tool for last years but now they added payment plans and lots of limitations. That's fine to charge money for a good service but such price is valid for a full project-managing tool, not just todo-list as a Quire.

All-in-one systema to manage project, lists, ToDo,... Sadly poorly usable in europe business due to privacy (GDPR) not compliant (server in USA,...)

Totally free with many premium functions.

I have use it for a couple hours, it seams promising
