I can't understand all the positive reviews.

So far this software is gives much less than a free Trello account. And having that said, Trello is actually very good with good UX and logic.

This tool seems developed from a team who doesn't understand the needs of the target users and lacks very basic features which every team who wants to manage their projects will need.

They definitely need new CTO if they have one, which I highly doubt.

So far this is the most useless tool I have ever bought from Appsumo.

Update to Igor's reply:

1. No, your platform doesn't seem overwhelming - it lacks key features.
For example, you can't tag/mention a specific user, nor can you share a link to a specific task.

Let's say I want to ask a team member for an update on a particular task - not possible.

That is not overwhelming, that is lack of basic features.

2. Maybe your goal is to provide something "more", but you need to start with the basics so that you cover the basic needs.

3. I compared it to Trello, just because it's free version delivers much more and in a convenient way.

I can't compare OneDeck to Monday for example or other tools on that level. It's out of their league, but they are more expensive. That is why I compared it to something that you can use for free.

4. I totally agree that in software like yours, which is very non-intuitive, you should have better onboarding, that is absolutely true. But the bigger issue is that you lack fundamental features.
