On the other hand, I found it incredibly useful. My mind often wanders when I read, and Squirt solves that.

I found their choice of color scheme jarring. They highlight a specific letter in blue for some reason, and you get a strange optical sensation after staring at that shade of blue for too long. I had to download their js and css, rehost it myself, search through it for the color code, and change it to black. But then I found it very useful.

I suspect that's done to help anchor your focus, i.e. so your eyes don't move too much

Perhaps adding a little bit of grey to the blue would help?

I agree with you. I've found it extremely useful to quickly pass through light reads. But sometimes, I wish there was a feature to display 'fixed width', that way small words can be combined, and will give more fixation time at higher speeds.
