A lot of modern designs have flat controls with no tactile cues that renders them unusable for the blind. Being able to connect with an app using VoiceOver makes the device accessible.
Even non iot kitchen tech is ridiculous. I tried to buy an oven with as few features as possible. I foolishly assumed that two knobs meant “mode” and “temp”. Nope. It has loads of features which you access by clicking and holding and twiddling one while opposite twiddling the other. Smeg.
