Great App in total with only a few small complaints I collected: • No dark mode – It would make the app so much easier to use in morning hours and fit better into dark systems. • The course list can't be simply edited; only reset and redone – Especially, when there is only one course that was mischosen this is a big hassle • Limited colors for courses – This is my last and a rather small complaint, but with more than just a few courses it would definitely be helpful to get a few more color choic

Functionality ok. But it uses an IMMENSE amount of mobile data or wifi data. Seems to be downloading the photos attached to recent posts over and over, each time I open the app. Just now I opened the app and it downloaded 1GB (over wifi), due to a bit of scrolling through recent posts (to which the teacher had added maybe 100 - 150 photos). I can't chance that behavior via Settings. The downloads continue even as I send the app to background. :-(

Half the negative reviews seem to be mad parents that are unable to navigate the app. But in my case the app works great, it does what its supposed to and it's easy to use. But please for the love of god add dark mode my whole phone is in dark mode and I keep getting flashbanged at 6 in the morning. minus another point for still not having dark mode

Thank you for your feedback! We’re sorry that dark mode isn’t available yet. We know this is frustrating. Our product team is currently working on other features that are a bit more urgent for many users. But dark mode is just a matter of time. Until then: Thank you for your patience! Best regards from the Sdui team
