What Teachers & Administrators Are Saying
Trusted by lecturers and students across Sri Lankan universities
"We have a lot of students on medical programmes who do half-day practicals. Before this tool I was manually counting 0.5s in a spreadsheet. Now I just enter the numbers and get a printable report in seconds."
"The automatic conversion from half-days to effective days is the feature we needed. Our previous system counted every absence as a full day which was unfair on students who attended mornings only."
"Being able to set a custom satisfactory threshold is important for us — different programmes have different requirements. The borderline status alert has already helped us catch at-risk students early this term."
"The printable report is clean and professional enough to attach to parent communication letters. It clearly shows full days, half days, effective total, and the overall rate — no parent has questioned the calculation since we started using it."
