The only reasons I can come up with are if the laundry is on a different floor it might be handy to check if it has finished before you go downstairs to unload it. It might also remind you if you don’t unload it which could definitely be handy. Or it could give you a bit more control over programming if it has a decent app - it’s easier/cheaper to build in more variables into an app than it is to have hard buttons. My rice cooker has an app which gives you access to a lot more detailed programming than you can do on the panel, like setting the exact finish time for the times, adjusting default times to your preferences, programs for yoghurt etc. Plus it allows multilingual settings - the cooker has chinese on all the buttons but the app is in English.
