Sad. I will check the next time before buying a Bosch product.
Though my main point is, that it is not hard to find products that work fine without an app. E.g. I just checked the Bosch site and could find many models that support delayed start, etc. with on-device buttons. In fact, the one that I picked somewhat randomly, the primary feature the app adds is that you can start the dishwasher remotely, which is the only feature I'd expect to need an app for.
(I completely believe that some of these manufacturers will also have models where they save on on-device buttons/displays by requiring an app.)
It's hard to figure out if a device will work to spec offline.
For instance, our home HVAC shipped with blatant firmware bugs that eat blower fans, lock up compressors, etc, but take a few years to do it and access to the hidden service menu to diagnose.
Eventually, I broke down and put it online to get the firmware update (after a $500-1000 fix "in warranty").
(It's a Bryant.)
