Because nothing screams like "great UX" and "QOL" like a tablet in a greasy kitchen you can't operate when your hands are full, and having to learn to code in order to use a timer.
HN is a diverse bunch. There are lots of non-technical people here. But even ignoring that, there's a hell of a difference between 'knowing to how to code' and 'knowing how to write an Android app'. I've been writing code for 25 years, and I know for certain it'd take me several evenings to be able to make a working Android app, and a lot more to make one I was actually happy with to the point I'd use it.

Absolutely, and absolutely. But if one is keen on QoL boosts, coding remains a foremost helpful skill, and currently coding for mobile devices is a further booster.
> several evenings ... and a lot more
I would suggest that the amount of competence to get you started to the point of applications usable to your satisfaction is probably lower than you seem to suggest (if you are already proficient in Java); and that the amount of blasphemy you could spend against the workings of the available libraries and time lost in code that "should just work" is probably not only in general underestimated, but really in this realm you would meet it a lot in practice.

So in other words it's probably not lower than suggested.
And certainly higher than the skills required to order and plug in a home assistant that offers a superior interface (doesn't require clean and free hands)
I can code, and I already have a tablet in the kitchen as a recipe book. But my hands are often either dirty, or in nitrile gloves, both make using the tablet either awkward or impossible. My workflow is to open the recipe I want, and then not touch the tablet until I’m done.
Not to mention that voice enables me to do this while also doing something else with my hands, like cutting veggies.
Android? We should have libraries for voice command (probably around android.speech ). I checked once because I would like to be able to voice control a GPS and mapping system while driving. If you wanted to voice control the application, that would be surely much more challenging, yet possibly interesting and exportable to other future needs.
This given, for the specific needs as you presented them I would have taken an old tablet, coded the feats you needed (timer, converter etc) in a single interface, fixed it in some most appropriate part of the kitchen for that use, and covered it with some plastic wrap film (I think standard PVC should be capacitive display friendly) in order to keep electronics and mess separate.
Of course, if you are more comfortable with the assistant, that is anyone's prerogative. Just reasoning.
At HN?!
> when your hands are full
One would never be empty handed while cooking?!
