Grist is a very powerful tool and more versatile than Airtable. It has a lot of potential to be THE tool every company needs.

I was impressed with the quality of the product, especially when compared with Stackby, another Appsumo product currently on sale. Unlike Stackby, Grist has very little bugs and glitches. Their support is responsive and works in the US time zone.

However, I haven't been able to take full advantage of it because of the following:

1) The tutorials go over things way too fast. I watched them several times and still couldn’t follow completely. The written instructions aren't much better.

2) Airtable is very successful because it makes things so easy and intuitive that even a lay person can easily set up their own system. But not Grist. There is no way anyone who hasn't taken a programming class before will know how to use python, formula, etc, at least not very easily. If you want to attract the mass market users, you've got to make it more user friendly. Right now, it is very far from it... unless you just want to attract the engineer-entrepreneur users.

3) It still needs more comparable features, e.g. calendar, conditioned-based coloring, webhook, formatting options, etc.

I hope I will eventually figure out how to use it fully, so I can update this review with how useful it can be.
