Repertory software comparison in 2026 — five platforms

Choosing repertory software in 2026 comes down to five live platforms answering the same question differently: which repertory, on which device, at what cost, with how much automation. RadarOpus, Synergy Homeopathic, Complete Dynamics, Hompath, and Similia sit side by side below on libraries, platforms, pricing, AI, and data portability — with the practice profile each one fits.

The five at a glance

1. RadarOpus — the Synthesis desktop suite

RadarOpus, published by Zeus Soft in Belgium, is the desktop incumbent built around the Synthesis Repertory and one of the largest licensed libraries in the field. It sells as tiered perpetual-licence packages from student to institutional editions, runs natively on macOS and Windows, stores patient data locally, and connects to the Clificol case-data project. Its argument is depth: decades of licensed repertories and materia medica in one install.

• Flagship: Synthesis Repertory, exclusive to the platform
• Library: broad licensed catalogue of repertories and materia medica
• Pricing: tiered perpetual licences; quotes via vendor and resellers
• Platforms: native macOS and Windows
• Data: stored locally on the practitioner's machine
• Fits: established prescribers committed to Synthesis who want maximum owned library depth on a desktop they control.
• Trade-off: high up-front cost, per-machine licensing, and an interface that has modernised more slowly than the feature set.

2. Synergy Homeopathic — MacRepertory and ReferenceWorks

Synergy Homeopathic — formerly Kent Homeopathic Associates — publishes MacRepertory for repertorization and ReferenceWorks for materia medica search, a pairing with deep roots in Mac-based practice since the late 1980s. The analysis graphing and the breadth of ReferenceWorks' searchable texts remain distinctive; perpetual licences are tiered by library size.

• Components: MacRepertory plus ReferenceWorks
• Heritage: Kent Homeopathic Associates lineage, Mac-first since the 1980s
• Pricing: perpetual licence packages tiered by library
• Platforms: macOS and Windows desktop
• Analysis: multiple graphing and weighting views
• Fits: long-established practices, often Mac-based, already invested in the MacRepertory and ReferenceWorks ecosystem.
• Trade-off: slower release cadence, pricing that requires a sales conversation, and no cloud or AI route.

3. Complete Dynamics — the Complete Repertory home

Complete Dynamics, developed by Eduard van Grinsven, is the canonical home of the Complete Repertory and is distinctive for a genuinely usable free Browser Edition alongside paid Practitioner and Master editions. It runs on macOS, Windows, and iOS with the same repertory across all three, which makes it a frequent recommendation for prescribers who want Complete without committing to a heavy desktop suite.

• Flagship: Complete Repertory, maintained by Roger van Zandvoort
• Editions: free Browser, paid Practitioner, paid Master
• Pricing: annual subscription by edition; Browser free
• Platforms: macOS, Windows, iOS, and a web view
• Data: local with cross-device sync on paid editions
• Fits: practitioners centred on the Complete Repertory who want a lighter footprint and a no-cost entry point.
• Trade-off: a single-author library focus, fewer integrated materia medica texts than the largest suites, and limited AI tooling.

4. Hompath — the long-standing Indian platform

Hompath, from Mind Technologies in Mumbai, is one of the oldest commercial homeopathy platforms, with a large repertory and materia medica catalogue and a range that runs from the Classic desktop product through web and mobile editions. It has long been popular in the Indian subcontinent and ships several analysis and clinical-tip modules; recent editions add AI-assisted features alongside the traditional repertorization workflow.

• Heritage: Mumbai-based, one of the earliest commercial platforms
• Library: large repertory and materia medica catalogue
• Pricing: perpetual and subscription tiers by edition
• Platforms: Windows desktop, web, and mobile editions
• Extras: clinical-tips and analysis modules; some AI tooling
• Fits: practitioners in markets where Hompath has strong support, and those who value its clinical-tips and module breadth.
• Trade-off: regional pricing and support variation, and an interface density that takes time to learn.

5. Similia — the cloud platform with AI workflows

Similia is the cloud-native entry: nothing to install, a Free plan with classic repertories and semantic search, and Pro tiers from $19.99/mo USD that add unlimited cases, AI-assisted notes and photo analysis, Live Audio Mode (Beta), and premium libraries — Murphy's MetaRepertory, Complete Repertory 2026, and Saine Repertory 2025 — by edition. Cases sync across devices, sharing is built in, and the platform is HIPAA-ready and GDPR-compliant with AES-256 encryption at rest.

• Pricing: Free core; Pro Base $19.99/mo USD; Murphy or Complete editions $29.99/mo USD; annual saves roughly one month
• Libraries: classics free; Murphy, Complete, Saine premium; add-ons mixable
• AI: semantic search free; notes-to-rubrics, photo, live audio on Pro with credits
• Platforms: web — desktop, tablet, phone with one account
• Security: TLS 1.3 in transit, AES-256 at rest, export and deletion controls
• Fits: practitioners who want multi-device access, modern search, and AI assistance without a large up-front licence.
• Trade-off: no offline mode, AI features consume metered credits, and premium repertories are subscriptions rather than purchases.

You can try the free repertory search directly in the browser before committing to any tier.

Where each one fits

Five clean decision lines fall out of the comparison. For owned library depth, RadarOpus leads on Synthesis plus the largest licensed catalogue. For legacy Mac-practice continuity, Synergy is hard to replace. For a Complete Repertory practice on a budget, Complete Dynamics offers a free Browser and a light footprint. For markets where it has strong support, Hompath brings breadth and clinical-tips modules. For multi-device access, modern search, and AI-assisted workflow at the lowest entry cost, Similia starts free and tops out lower at the paid floor. The expensive mistake is buying one platform's strength while needing another's.

FAQ

Can I move cases between these platforms?

Not cleanly. Each platform uses a proprietary case format, and none documents a direct importer for the others' files as of May 2026. Exports — PDFs, documents, data files — preserve content for re-entry, but expect manual work.

Which is cheapest over five years?

It depends on volume. A free Browser (Complete Dynamics) or a Free plan (Similia) costs nothing for low-volume work. A perpetual desktop licence is a larger up-front cost that is then owned, while a subscription continues but includes updates without upgrade fees. Similia Pro Base at $219.99/year USD totals roughly $1,100 USD over five years, in the territory of a mid-tier desktop licence.

Do the desktop suites offer cloud editions?

RadarOpus and Synergy remain desktop products with local data as of May 2026. Complete Dynamics adds iOS and cross-device sync on paid editions. Hompath ships web and mobile editions alongside its desktop product. If full multi-device cloud access is a hard requirement, that constraint narrows the field quickly.

Is the AI difference decisive?

Only if it matches the workflow. Semantic search, notes-to-rubrics, and live transcription compress real consultation work, but a prescriber working from paper notes on one machine will not miss them. The gap matters most in high-volume and teleconsultation practice.

Verdict

Choose RadarOpus for owned depth, Synergy for Mac-practice continuity, Complete Dynamics for a light Complete-centred setup, Hompath where its support is strongest, and Similia for cloud flexibility and AI assistance at the lowest entry cost.
