Who should consider a PrimeTimetable alternative?
If your school uses PrimeTimetable, or you are evaluating it alongside other cloud tools from the best school timetable software 2026 roundup, this page is for you. PrimeTimetable is a web-based scheduler for automatic and manual timetabling on any device, and the vendor reports use across more than 100 countries in primary, secondary, international schools, universities, and events. It has transparent annual pricing and a free trial. This is a fair comparison, not a takedown.
The short version: PrimeTimetable centers timetable generation across devices with a mature generator. Smootables is school year planning-first. The two differ in institution fit, planning depth, and how much year and pathway modeling sits in the product before generation.
Where does PrimeTimetable work well, and where do vocational or planning-first schools look elsewhere?
PrimeTimetable is a strong fit for small-to-mid schools that want low-cost cloud scheduling on any device. The columns below show where PrimeTimetable works well and where vocational, technical, or planning-first schools may prefer the Smootables model.
Where PrimeTimetable works well
Schools that want cloud, cross-device access on desktop browsers, iOS, and Android, with an offline mode for purchased customers and a RESTful API for published-timetable data. Its automatic generator resolves conflicts and forbidden positions and optimises subject distribution, teacher and student load, gaps, building moves, and room usage, with drag-and-drop manual editing.
PrimeTimetable also has transparent annual pricing with a free trial, a user guide that covers teacher substitution, and a UI available in French, Spanish, and German plus auto-translate. Hosting is in US data centres with an ISO/IEC 27001:2013-certified provider, GDPR ready, with daily backups.
Where vocational and planning-first schools look elsewhere
PrimeTimetable's documented surface centers generation, editing, and publishing. At capture, no academic-year planning model, work-based learning, or individual-pathway planning was described on its pages, and public review volume is thin (a main aggregator showed a single verified review). Independent comparisons note the interface and setup can feel complex and that some training is needed.
For vocational college timetable software buyers and schools with mixed cohorts, the gap between 'the grid generates' and 'the year plan is feasible' is where much of the planner time goes. Smootables puts period planning, workload, pathways, resources, validation, and editing into the same model before generation.
How is Smootables different from PrimeTimetable?
Smootables shares the same broad category: cloud timetabling with automatic generation and hard and soft constraints. It starts earlier in the lifecycle. The planning model holds academic years, terms, periods, courses, modules, pathways, workload, and individual student assignments. Generation runs against that model (see automatic school timetabling), so validation can catch likely infeasibility before the solve. For a step-by-step creation guide with Smootables workflow at each stage, see how to create a school timetable.
The solver uses Google OR-Tools CP-SAT with 11 hard constraints and 6 weighted soft constraints, 12 pre-generation validation checks, typed infeasibility reports, a waiting area for deferred lessons, and timetable branches for scenario recovery. A built-in AI planner assistant lets planners describe changes in natural language and review bulk updates on the same planning model the solver uses.
How does Smootables compare to PrimeTimetable in 2026?
The table contrasts PrimeTimetable and Smootables across workflow, planning depth, validation, pathways, AI, deployment, pricing, and export. PrimeTimetable is strong as a low-cost cross-device generator; Smootables is planning-first, so several rows reflect where the data lives rather than whether a solver runs.
| Dimension | PrimeTimetable | Smootables |
|---|---|---|
| Workflow | Cloud data entry, automatic generation, drag-and-drop manual editing, publish | Planning-first, then generate a timetable from the plan in one step |
| Year and period planning | Generator with statistics and multiple views; no year-planning layer described at capture | First-class part of the model |
| Individual pathways and work-based learning | Broad constraint handling for class-based scheduling; no work-based-learning or individual-pathway model described at capture | Group, individual, and per-placement exemption support in the core model |
| Pre-solve validation | Validation and conflict resolution during generation | 12 validation checks before generation, with typed infeasibility reports |
| Automation and AI | Automatic generator that resolves conflicts and optimises load, gaps, and room usage | CP-SAT solver plus a built-in AI planner assistant for in-app actions |
| Deployment and API | Cloud on desktop browsers, iOS, and Android; offline mode for purchased customers; RESTful API; US data centres with an ISO/IEC 27001:2013-certified provider | Cloud SaaS on AWS and Microsoft Azure with regionally scoped locations |
| Pricing | Free 30-day trial, then Basic $149/year up to 40 teachers and Premium $299/year up to 100 teachers (captured Jun 2026; verify current pricing) | Evaluated through a demo and pilot; the comparison that usually matters is planner hours saved |
| Publication and export | Export, share, print, and publish timetables online | PDF and Excel export plus read-only teacher views; SIS and calendar integrations are available |
What should schools validate when replacing PrimeTimetable in 2026?
When deciding whether Smootables is the right replacement, these are the scenarios where the planning-first model usually shows the biggest difference:
- Modeling workshops, work-based learning, and individual pathways without a parallel spreadsheet
- Running pre-generation validation on a known-tight period
- Comparing scenarios with timetable branches instead of overwriting drafts
- Checking workload before any timetable is generated
- Reviewing a multi-year planning view with timelines spanning three to five years
What is the migration path from PrimeTimetable?
Moving off PrimeTimetable is a parallel run, not a big-bang switch. Compare TimetableMaster alternative if you are also evaluating other cloud generators. The steps below export your PrimeTimetable data, import it into Smootables, validate before scheduling, and run one term in parallel before you change the published source of truth.
- Export your current model from PrimeTimetable using its export or published-data options.
- Import the model into Smootables using structured import with column mapping, or AI-assisted extraction for older exports.
- Validate the model in Smootables. Pre-solve validation will surface mismatches that are easier to resolve before scheduling.
- Run one term in parallel. Keep PrimeTimetable as the published source of truth while you verify the Smootables result.
- Switch publication for one scope (campus, program, or term) once the parallel run looks correct.
- Roll out to the rest of the school in subsequent cycles. We support piloting and data migration so testing Smootables is fast and practical.
Questions schools ask when comparing PrimeTimetable and Smootables
Is Smootables a direct replacement for PrimeTimetable?
Yes, for planning, generation, editing, and export. Most schools roll over in safe steps: import your PrimeTimetable data, validate the model, run one term in parallel, and compare results before you change what is published. We support data migration and help you verify outcomes so you switch fully only when the Smootables run is right.
We chose PrimeTimetable for its low annual pricing. Do we lose that with Smootables?
PrimeTimetable's transparent annual bands are a real advantage for small-to-mid schools. Smootables is evaluated through a demo and pilot, and the comparison that usually matters is planner hours saved across planning, validation, and regeneration, not licence line items alone.
We rely on PrimeTimetable's REST API. Does Smootables integrate with our systems?
Smootables offers integrations with SIS and calendar systems. If a specific API workflow is important, describe it during a pilot so we can confirm the fit before you commit.
PrimeTimetable runs on iOS and Android. Is Smootables mobile-friendly?
Smootables is cloud SaaS and runs in the browser across devices, with read-only teacher views for published timetables. The difference is the planning model and validation layer before generation, not whether the product runs on the web.
PrimeTimetable's automatic generator is mature. Why switch?
Generation quality is rarely the deciding factor. The bigger gain is the time before and after generation: validation that catches problems earlier, workload visibility before publication, and editing that keeps the planner in control afterwards.
