GPS
Where the phone is
You set the room's boundary once, by standing in it. A check-in from outside that circle is refused. A shared code can travel across campus; a location cannot.
Class attendance for universities
They were there.
They were there.
Sejeli proves it.
Students check in from their own phone. Sejeli confirms they are physically in your room — by GPS, by a code that changes every twenty seconds, or by Bluetooth when there is no internet at all. You get the record. You keep the lecture.
- Confirms students are really in the room
- A code that changes every 20 seconds
- Works even when the Wi-Fi does not

How it works
Three ways to know a student is in the room
A check-in is a claim. Sejeli does not take the student's word for it — the phone has to prove where it is, and it can do that three ways. The last one is the reason this exists.
Rotating QR
A code that expires
The code on your screen regenerates every twenty seconds. A photo of it sent to someone at home is worthless before it arrives.
Bluetooth
Heard, not reported
Basement labs. Halls with two hundred phones on one access point. Days the campus network simply goes down. When GPS cannot get a fix and there is no connection, your phone and your students' phones hear each other directly over Bluetooth, and attendance is recorded from that — with no internet at all. The record syncs when a connection comes back.
This is the hard part, and it is the reason to choose Sejeli over a form with a link in it. A form needs the network. A room does not.
Why Sejeli
The record writes itself. You just teach.
Everything below is built and running today. Nothing on this page is planned — it is what the app does.

Percentages against your policy, not a default
Set the thresholds your faculty actually uses. Sejeli measures every student against them, per lecture group and per lab, and tells you when a warning is due — before exam week, not after.

Lectures and labs, each with its own schedule
A lab group keeps its own timetable and its own roster. Cancel a session for a public holiday with a reason, and it drops out of every student's percentage instead of counting against them.

One tap to Excel, CSV or PDF
The moment a session ends the record is final. Export the term whenever the department asks, in the format they ask for, without reconciling anything.
- Live rosterWatch check-ins land while you teach. Mark a late arrival by hand if you choose to.
- One student, one phoneAn account binds to a single device at registration. Nobody checks in two people from the back row.
- Appeals with evidenceA student can attach a photo of a medical excuse. You decide, from the record.
- Data that does not lingerCourse records clear themselves after the term ends, with an export reminder first.
- Free for instructorsChecking in is never behind an ad. An institutional, ad-free tier for universities is planned.
- Your faculty, scopedEach institution has its own directory and ID space. No guessing which "Y. Hany" is yours.
A day with it
Tuesday. Lab A1. The Wi-Fi goes.
-
9:58
You start the session on the way in
Open Lab A1, tap Start. The check-in window is open before you have put your bag down. The room's boundary was set once, in week one.
-
10:01
Phones check in from the bench
One tap each. Nobody reads a list aloud, nobody passes a sheet, and the students who are not there are the only ones you have to think about.
-
10:03
The network drops. Nobody notices
Your phone keeps listening over Bluetooth; theirs keep answering. The check-ins are recorded in the room and sync on their own when the connection returns.
-
10:15
The window closes itself
Late arrivals can no longer check themselves in. You can still mark one from the roster — with the time they actually arrived, so "I was there" is a fact on the record and not a debate in your inbox.
-
12:00
The record is already final
Nothing to enter, nothing to reconcile. A student who has slipped under your policy is flagged, and the warning is one tap away from their record.
Your students
They will not need a tutorial
The student side is one screen. Register once with a student ID, then every session is a single tap. The phone can stay on the desk with the app open — that is all Bluetooth needs.
- They see their own percentage and any warning the moment it is issued, so nothing is a surprise at exam time.
- A missed check-in tells them straight away, in the room, while it can still be fixed.
- Students use the Sejeli app on their phone. There is no student website and no password to forget.
Are you a student? Sejeli for students is a phone app. Your instructor will send you the install link.

Where it comes from
Built in a dental lab, by the person taking the roll
Sejeli was made by a dentistry demonstrator in Egypt whose lab sections kept losing teaching time to attendance — and whose rooms do not always have a signal. It is not a concept. It runs on real phones today, and its first faculty pilot begins in late September 2026.
