These utilities run in your browser. Paste or type school data locally, see the method in plain language, and export or print results. They cover one planning artifact at a time. Smootables handles multi-period optimization, constraint solving, and publication across the full year plan.
Use the school week rotation calculator to show Week A or Week B on your website, the teaching load calculator for FTE checks, or turn a weekly timetable into an ICS file for Google Calendar, Apple Calendar, or Outlook. The circular year planner draws an editable school year wheel you can filter and export as PDF, CSV, Excel, JSON, or ICS, or share as a read-only link or iframe embed.
Calculators
School week rotation calculator
Show which rotation week your school is on (Week A, Week B, or a longer cycle). Configure the cycle, anchor date, and holidays, then copy an embeddable widget for your school website.
Open tool →Teaching load calculator

Converters
Preview and edit school timetable calendar files (.ics) in your browser
Open your school timetable’s calendar export and see every lesson as a real calendar, by class, teacher or room. Spot double bookings, drag lessons to new slots, edit their details, and download an updated .ics file that keeps everything else from the original. Free, and nothing is uploaded.
Open tool →Timetable to ICS calendar converter
Convert a weekly school timetable to a downloadable ICS file for Google Calendar, Apple Calendar, or Outlook. Set term dates, skip holidays, and add an optional A/B week rotation.

School Planners
School circular year planner
A school year scatters across separate calendars: exams here, staff training there, holidays somewhere else, until nobody can see the whole year at once. This free planner puts every date on one circular wheel, ringed by team and color-coded by category, then exports to PDF, Excel, CSV, a share link, an embed, or a calendar file. No signup.
Open tool →Software Requirements Builder for Schools
Free AI-powered tool that turns vague intentions into clear, measurable, tender-ready requirements for school software. No login required, and your document stays in your browser.
