"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."

School Administrator
★★★★★

"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."

Yuki Tanaka
Student Welfare Coordinator
★★★★☆

"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."
