NMR Calculator 2 vs StudGo

The app shows a list of isotopes with non-zero nuclear spin angular momentum. Select an isotope to view its NMR properties and calculate fundamental NMR parameters. Information section For a chosen isotope, this section displays the atomic symbol with mass number, nuclear spin angular momentum, gyromagnetic ratio, and natural abundance. Calculator section Update any one parameter in a subsection to recalculate the others. - Larmor frequencies: External magnetic field and the corresponding Larmor frequencies for the chosen isotope, the proton, and the free electron. - Time domain: Number of data points, acquisition duration, and dwell time. - Frequency domain: Number of data points, spectral width, and frequency resolution. - Pulse 1: Pulse duration, flip angle, and RF amplitude in Hz and μT. - Pulse 2: Pulse duration, flip angle, RF amplitude in Hz, and RF power relative to Pulse 1. - Ernst angle: Ernst angle and repetition time for a given T₁ relaxation time. NMR Assistant An on-device AI assistant scoped to NMR topics, available where Apple Intelligence is supported. Ask questions in plain language — the assistant answers using the same calculation engine that powers the calculator, so results are always physically consistent.

StudGo is a private, open-source student project and not an official app of any university. It is developed by a student. The app is a client for Stud.IP and signs in to your own university's Stud.IP through the official OAuth2 interface. It brings your study day into one app instead of spreading it across five browser tabs. You sign in with your own university account, directly at the university. StudGo has no server of its own. TODAY The start screen answers the one question that matters in the morning: what's on? Your next class with room and time, the rest of the day below it, unread messages and new announcements. WIDGETS Your next event and unread messages as widgets on the Home Screen and the Lock Screen: small, medium with “Then”, round or rectangular below the clock. When an event ends, the widget moves on to the next one by itself. The widgets never contact the server themselves. TIMETABLE The weekly grid you know, plus a day view and a list of events. Events arrive as real sessions with dates, including room, topic and cancellations. Switch between the current and the upcoming semester. Share your timetable as an image, for example with your study group. IN iOS CALENDAR If you like, the next eight weeks appear in a separate “StudGo” calendar that updates every time you open the app – so they also show up on Apple Watch, in CarPlay and in Siri. Turning it off removes the calendar again. PUBLIC HOLIDAYS Lower Saxony's public holidays appear next to the date on the start screen, in the day view and in the list, so a day off no longer looks like a forgotten event. COURSES All your courses with description, lecturers, participants, events, announcements, forum, wiki and the course's courseware. Plus search across the entire course catalog. FILES Every course's file area: browse folders, preview and share files, upload your own files, create folders. INBOX Messages and Blubber conversations in one place. Read, reply, delete, write new ones. In Blubber chats, tapping a person opens their profile. CAMPUS Activity stream, contacts, people search, office hours with booking, study groups, institutes, cafeteria menus in day and week view, and statistics about your own semester. REMINDERS Local reminders before classes and events, plus a notice about new messages. Without any push server. ENGLISH AND GERMAN The app follows your device language, with eight color themes, light or dark. Text follows your preferred text size. TRY IT WITHOUT AN ACCOUNT On the sign-in screen, “View demo without signing in” opens a complete version of the app with sample data. No account, no network connection, no data transmitted. WHICH SERVER This version is set up for the Stud.IP at studip.uni-hannover.de; other Stud.IP installations are not supported at the moment. Signing in requires a valid account there. Without one, you can explore the full app in demo mode. PRIVACY StudGo has no server of its own. The app talks directly to your university's Stud.IP with the account you sign in with. For cafeteria menus it queries the open directory OpenMensa, without any account or identifier. Access tokens are kept in the device's Keychain, cached content inside the app. Calendar sync writes only to its own “StudGo” calendar and reads no other events. No analytics, no tracking, no ads, no sharing with third parties. The app never sees your university password: sign-in runs through OAuth2 in the system browser, directly at the university. GOOD TO KNOW Exam registration and grades are handled in QIS, not Stud.IP; a button in your profile takes you there. Stud.IP is a trademark of Stud.IP e. V.; StudGo is not affiliated with it.
