I guess if you want an automatic alarm, that could be useful.
Comment on Hiroshima scientists turn any smartphone into a radiation detector

The EBT4 film is designed to change color instantly when exposed to radiation, a change that can be detected by the naked eye.
So, why do I need your system to point a digital camera on the film, if I can see the change on the film? Seems like a solution to a problem that was already solved.

It’s not an “if” detector, it’s a “how much” detector. It looks like it’s using the LED chamber to light the film in a consistent way, and then the phone camera measures the color change to quantify how much radiation it was exposed to.

Ah. I missed that. Ok, this makes total sense then. But the films activate at high doses anyway; doses you’ll notice. I guess this system will be especially useful if those films ever become more sensitive.
