Which tool fits which segment in 2026?
Most schools shortlist by segment before they compare vendors. These picks are honest starting points, not universal rankings.
Planning-first schools and colleges
Smootables fits schools and colleges that need school year planning, pathway modeling, and validation before the solver runs. Untis and aSc remain reference points for mature desktop generation.
Technical staff in smaller schools
FET is free, open-source desktop software with automatic generation and a wide library of scheduling rules. It fits smaller schools where technical staff can own setup and maintenance without a vendor contract.
Schools with mature desktop timetables
Untis and aSc Timetables remain the reference points for mature desktop generation, diagnostics, and long-established planner workflows.
K-12 volume and electives
Edval (Timetabler) combines Edval 10 master timetabling with Edval Choice for online subject selection and Edval Daily for cover and exam blocks.
Cloud entry for small schools
PrimeTimetable and TimetableMaster both offer browser access. PrimeTimetable publishes banded annual pricing; TimetableMaster advertises a free forever plan with AI-assisted generation.
K-12 class-based schools
Horarium fits elementary, middle, and high schools that want cloud timetabling with 40+ constraint types, Excel import, and self-serve help in 10 languages for setup and generation questions.
Which evaluation dimensions usually decide the shortlist?
Use this checklist after the segment picks above. It mirrors what procurement teams ask in demos:
- Planning depth: year, term, course catalog, pathways, not only weekly grids
- Pre-solve validation and infeasibility explanations before generation runs
- Teacher workload before publication, not only after
- Individual pathways, exemptions, and mixed cohort handling
- Daily change workflow after the timetable is published
- Deployment model: desktop, cloud, offline needs, and mobile access
- Data migration from spreadsheets or an incumbent tool
- Collaboration model: permissions, audit trail, and concurrent editing
- AI assistance that respects hard constraints and audit boundaries
- Total cost: licence, modules, implementation time, and ongoing planner hours
Where does each named tool work well?
Fair comparisons start with genuine strengths. The cards below summarize sourced positioning for each tool in this comparison.
Untis / WebUntis
A modular Windows desktop suite with mature optimization strategies, diagnostics, percentage planning, and separately licensed modules for cover, publishing, and student timetables.
aSc Timetables
A powerful automatic generator with configurable complexity, card-based editing, pre-generation advisor and verification tools, and an EduPage ecosystem for some schools.
FET
Genuinely free AGPL v3 software with a flexible constraint engine, cross-platform desktop and CLI builds, and operating modes for several national systems.
PrimeTimetable
Cloud-native scheduling with drag-and-drop manual editing, conflict resolution, substitution guidance in the user guide, and REST API access to published timetables.
Edval (Timetabler)
Deep algorithmic timetabling with option-line generation, class-list balancing, Edval Daily for daily variations, and integrations with 70+ admin systems.
TimetableMaster
Browser-only cloud access with AI-assisted scheduling, substitute and leave management, and PDF and Excel export.
Horarium
Fast constraint-based generation with unsatisfied-constraint reports, manual editing, and broad localized self-serve help for K-12 planners.
Smootables
A simple, easy-to-use cloud workspace for multi-year school planning and pathways, then timetable generation directly from the same plan without re-keying data.
How should schools shortlist timetable software in 2026?
Most teams compare against their current Excel or manual timetabling workflow first, then run one real program through two or three finalists. For the full planning process, see the school timetabling Learn guides. This page focuses on product fit.
- Pick your segment from the cards above (planning-first schools and colleges, technical staff in smaller schools, mature desktop timetables, K-12 volume and electives, cloud entry for small schools, or K-12 class-based schools).
- Shortlist two or three tools and model one real term, including pathways, workshops, or electives if they apply.
- Run pre-solve validation and generation; compare infeasibility explanations and planner hours, not only the finished grid.
- Pilot the strongest option for one term while the incumbent tool stays the published source of truth.
- Roll out school-wide once the pilot matches leadership expectations for workload, edits, and publication.
Where does Smootables fit in the 2026 market?
Smootables is built for schools that want year and term planning, resource assignment, and automatic school timetabling in one connected workspace. The product uses a Google OR-Tools CP-SAT solver with 11 hard constraints and 6 weighted soft constraints, 12 pre-generation validation checks, typed infeasibility reports, a waiting area for deferred lessons, branches for scenario recovery, and an AI planner assistant that edits through the same model the solver uses.
That planning-first stack suits vocational and technical colleges, multi-campus groups, and schools with individual pathways that outgrow spreadsheet discipline. Smootables is the option to validate when pre-solve validation, workload before generation, and natural-language plan edits matter as much as the finished period grid. It is newer than Untis, aSc, or Edval, so treat a parallel pilot as part of the evaluation, not an optional extra.
Questions schools ask when comparing timetable software
Is there one best school timetable software for every school?
No. Deployment model, institution type, elective complexity, and how much year planning you do before generation usually matter more than a generic ranking. The segment picks and table above are designed to narrow the field honestly.
How is this page different from the vocational buyer's guide?
The best timetable software for vocational schools page goes deeper on vocational evaluation dimensions. This page covers the whole category, including FET, PrimeTimetable, TimetableMaster, Horarium, and Edval (Timetabler), for schools that want a neutral 2026 roundup.
Does Smootables replace Untis, aSc, or Edval on day one?
Not necessarily. Many schools pilot Smootables for one program or term while the incumbent tool stays published. Smootables focuses on planning depth, validation, and AI-assisted editing; established suites may still win on specific modules or regional ecosystems you already rely on.
What Smootables capabilities should we verify in a demo?
Ask to see a multi-year planning view, pre-solve validation, an infeasibility report, the waiting area after a partial solve, branch comparison, individual pathway or exemption modeling, workload before generation, and an AI planner edit that respects hard constraints. Compare each one against your current tool's setup and tuning workflow.
