Keep in mind that phones have a pretty high per-use setup cost: 1) Not all phones are voice activated, you you have to pick them up

2) If you're cooking and your hands are occupied/covered, you're going to have a hard time using a phone with your hands. Phones aren't typically waterproof, and touchscreens don't typically work well with water on them.

3) If you use a screen lock on your phone, any app is immediately inconvenient given #2

This device seems to be designed specifically for the job, and has a low per-use setup cost.
