Was this a timed take home project or something with a flexible timeline? That is, was it "You have to respond within 3 hours of receiving this email with your solution" or something more flexible?
I mostly understand why some companies do the x hours routine, and when I've done interviews this way I've historically performed well, but it just felt like it added unnecessary stress. For instance, anyone on the job doesn't have to worry about issues like, "What if I couldn't get the app up and running because I had the wrong version of X installed?" longer than maybe their first day on the job. And if you plan on hiring an engineer for a few years, one day is irrelevant. At best this felt like it favored contractors who were more experienced at jumping into new projects frequently.
