Juho Isola, Smootables founder
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.
