Works with the internet down
Exams run over the school's own network. A dropped connection on exam day stops nothing, because nothing depended on it.
Building from Lagos, Nigeria
Software built in Nigeria, for how Africa actually works.
Logizon Technologies is a product company. We build and run our own software — starting with ExamSling, the system schools use to run exams, classrooms, attendance and accounts, entirely on their own network.

Our flagship product
ExamSling — The system your school runs on.
Exams, question bank, results and report cards, classroom and syllabus, attendance with fingerprint roll-call, the full bursary, and a parent app — one application, running on the school's own network. Exam day never waits on the internet.
Theory marked by AI, approved by a teacher
Theory answers are graded against the marking guide the teacher wrote. Low-confidence scores go to a review queue, and a manual override always wins.
A live control room
Watch every candidate's progress as it happens. Grant extra time to one student or the whole hall, broadcast a message, or end the exam with auto-submit.
Nothing gets lost
Answers autosave every ten seconds and survive a crash or a power cut. A student resumes exactly where they stopped.
Attendance by fingerprint
An attendance station takes roll-call from a fingerprint scanner or a barcode, so the register is done before the first lesson starts.
The bursary, not just the exam hall
Fees and payments, budget, payroll and expenses, procurement and financial reports — with bursar accounts that only see what they should.
Classroom and coursework
Assignments, class activity, syllabus tracking and learning materials sit beside the exam engine, so term work and exams share one record.
Parents in the loop
A companion mobile app gives parents their child's results, fee statements and school announcements — with scheduled notifications.
From question bank to results in one sitting
Exam day has enough going wrong already. ExamSling is built so the software is never the thing that does.
- 01
Build the bank
Load objective and theory questions by hand, import a JSON package, or convert an existing past-paper document into questions automatically.
- 02
Schedule the exam
Pick the questions, assign the classes and arms that sit it, and move the exam from draft to scheduled. Students get their exam numbers.
- 03
Students write
Candidates log in from any machine on the school network. Objectives, theory with working lines and a maths keypad, flagging, and a question map.
- 04
Results, same day
Objectives are marked on submission. Theory is graded against the teacher's rubric, flagged for review where confidence is low, then exported to Excel.
What we build
The same engineering that runs ExamSling in schools is what we bring to every product we take on.
Product engineering
We design, build and operate our own software end to end — desktop, mobile, web and the infrastructure underneath it.
Offline-first systems
Software that keeps working when the network does not. Local-first data, sync when you can, degrade gracefully when you cannot.
Applied AI
AI used where it earns its place — grading theory answers, converting documents into question banks — always with a human able to overrule it.
Mobile applications
Native-grade Android and iOS apps for the people on the other side of the product: parents, students, customers and field teams.
Payments & commerce
Collections, settlements and checkout flows built for Nigerian rails and the realities of local reconciliation.
Deployment & support
Installation, per-school branding, automatic backups and the ongoing support that keeps a deployment healthy after launch.
One company, several products
ExamSling is where most of our attention goes. These are the other things Logizon is building — and the ones still in the workshop.
