One verified feed per course
Every update from your lecturers and course reps, in its own course. Pinned posts first; urgent changes stand out.
Built for Nigerian universities
Every class update. From the source. On time.
Cancelled classes, venue changes and deadlines, posted by your lecturer or an approved course rep, verified, and on your phone the moment they go out. Not buried in a group chat.
Try it: post as a lecturer
The problem
The message that mattered got buried.
One line from the class rep says the venue changed. Then come a hundred others. By the time you open the chat, it has scrolled out of sight, and you are in the wrong hall.
81%
of students we surveyed have missed important information buried in a group chat: 100 of 124.
Same message. One gets buried. One gets through.
102

Why you can trust it
Every post carries a fingerprint. Try to change one.
Each post's fingerprint is built on the one before it, like links in a chain. Change or delete any post and every fingerprint after it stops matching. Anyone can check.
All 5 posts verify.
An illustration of how Classyn's verification works, not live data.
Verified at the source
Only a course's lecturers or an approved course rep can post to it, checked on our server. Every post says who sent it.
Never quietly changed
Posts are never edited. A correction is a new post linked to the old one, and any post can be checked from a public link.
Built for real networks
Notifications wait for your phone to reconnect. Calendar alarms ring with no data. Reminders still go out after an outage.

Questions
Frequently asked.
Who can post to my course?
Only the lecturers teaching it and course reps they have approved. That is checked on our server, not just hidden in the app, and every post shows who sent it. Your school admin can also send school-wide notices.
Can a post be edited or deleted after it goes out?
No. A mistake is corrected with a new post linked to the original. A lecturer can archive an old post off the board, but it stays on the record and can still be verified.
How do I know an announcement is genuine?
Each post carries a fingerprint built on the one before it, so an edited or removed post shows up when a course's history is checked. Tap Verify in any course, or share a public link that lets anyone check a single post.
What if my network is poor or I run out of data?
Notifications are tiny and wait for your phone to reconnect. Your timetable and deadlines can go into your phone's calendar, whose alarms ring with no data at all.
I have an iPhone. Where is the app?
The App Store version is coming. Today, open app.classyn.org in Safari and add it to your Home Screen: it opens like an app and gets notifications (iOS 16.4 or later).
Is my information private?
Your own plans, deadlines and GPA history are visible to you alone. Your matric number is shown only to your lecturers. You can download a copy of your data or delete your account from Settings at any time.
