Campus Köthen brings your daily student life together in one place—clear, privacy-focused, and specifically developed for students at the Köthen campus. With the app, you have essential information and personal university services right at your fingertips: • Current campus news from your selected channels • Canteen menus for Köthen's dining halls with filters for dietary preferences and allergens • Available timetable, campus, and Moodle events consolidated into a shared calendar • Contact details and points of contact for key study-related questions • Your student email inbox with folders, search, attachments, and reply functionality • Grade overview from HIS-QIS or HISinOne • Moodle courses, materials, assignments, announcements, and submission deadlines • Local tasks and reminders • Financial requests and feedback submitted directly to the Student Council's (StuRa) committee system • German and English user interface, including support for light and dark modes Your data remains under your control: Campus Köthen does not require a dedicated user account and uses no advertising, analytics, or tracking services. Settings and personal content are stored locally on your device. Credentials are saved in the secure keystore/keychain; cached emails, grades, and Moodle content are stored encrypted. The app connects personal university services directly to the respective university systems. Your credentials, emails, grades, and Moodle content are not routed through the Campus backend. Moodle access is read-only. Thanks to local caching, much of your previously loaded content remains accessible even without an active internet connection. Outdated or offline-cached data is clearly flagged within the app. Campus Köthen is not an official app of Anhalt University of Applied Sciences. The app is developed independently and distributed via app stores by Erik Engler, operating under "Leviora Studio." The Campus backend and editorial content are managed by the legally independent student body (Studierendenschaft) of Anhalt University. Anhalt University itself is neither the developer nor the operator of the app.

Verdict
The clearest difference is in-app purchases: Campus Köthen at none against Hazelnote's 4. Hazelnote's advantage is update cadence (every 5 days vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
