This is our second Bosch dishwasher. The first one had some issues: it leaked, the soap dispenser wouldn't open, one of the washer arms  kept flying off, and it finally just stopped altogether. You'd think I'd never buy another Bosch. But I did. This one has worked great for the month we've had it. The alert is so soft that we don't hear it when the dishwasher has finished. The app will send a notification when it's done. Other than that, the app is pretty worthless.
