Anita Perera

Deputy Principal

★★★★★

"We used to build the bell schedule in Excel every term and recalculate every time a period changed. This tool recalculates everything instantly when I change one duration — it cut my prep time in half."

James Okonkwo

School Timetable Coordinator

★★★★★

"The auto bell-time calculation is the feature we needed most. I enter the start time once and every bell in the day is computed automatically. The PDF export is clean enough to pin on the staffroom board."

Mei Lin Tan

Academic Administrator

★★★★☆

"Very useful for building out our hybrid day structure with double periods and shorter breaks. The instructional minutes total helps us confirm we meet the regulatory minimum without counting manually."

Fatima Al-Rashid

Curriculum Coordinator

★★★★★

"Simple enough to use on the spot during a staff meeting. I built three alternative schedules in ten minutes and shared the CSVs with our head of school for comparison. No software to install."
