I also would like to highlight something which is not particular to Focusmate but rather a phenomena spreading to all these SaaS platforms: Focusmate is not free. It's a paying product that costs $5/month.
There is absolutely no details of pricing on the home page. There is no pricing page on the website. The FAQ itself doesn't mention pricing. This will only come up after you signup and start using it. There are details on the blog but that's about it.
It really gets on my nerves when services do that and I decided to ignore anything that ignores my right to know the price beforehand. But I can see it working with the general public for a while.
