If you're choosing between Complete Dynamics and Similia in 2026, the short version: Complete Dynamics is a long-running homeopathy desktop application anchored by Roger van Zandvoort's Complete Repertory, with a genuinely useful free Browser Edition and paid Practitioner / Master tiers. Similia is a cloud-native platform with a free forever tier that already ships seven classical repertories and five AI features — semantic search, Notes-to-Rubric, AI analysis, live audio transcription, and AI Photo Analysis — plus complete cross-device case management. Both have free tiers worth using; the right choice depends on whether you want an offline desktop reference centred on one deep repertory, or an AI-assisted browser workspace that follows you across devices.

What is Complete Dynamics?
Complete Dynamics is a homeopathy practice and repertorisation application developed jointly by Roger van Zandvoort (the homeopath behind the Complete Repertory) and software developer Edwin van Grinsven, who has been practising homeopathy since 1998. Per the Complete Dynamics review on homeobook.com, the project was founded around the idea that "Complete Dynamics is the first and only program that runs native on Windows, Mac, and Linux," with mobile companion apps for iOS and Android.
There are three editions. The Browser Edition is free, lifetime, and gives anyone access to the full Complete Repertory with search and browse. The Practitioner Edition adds case management, analysis, and a materia medica library on a subscription basis. The Master Edition adds advanced features such as rule-based differential analysis, remedy suggestion, and automation utilities. Pricing on the official completedynamics.com site is €19/month for the Practitioner Edition and €28/month for the Master Edition as of May 2026. The Saine Repertory 2025 is available as a separate paid add-on alongside the Complete Repertory, and additional repertory and materia medica extensions can be purchased on top.
The Complete Repertory itself is the centrepiece. According to Complete Dynamics' own materials, it contains around 2.3 million remedy additions across roughly 206,000 rubrics — by some measures the most exhaustive synthetic repertory in active development. Complete Dynamics does not advertise any AI features (semantic search, transcription, photo analysis, notes-to-rubric extraction) on its public website at the time of writing.
What is Similia?
Similia is a modern, cloud-native homeopathy platform with a free forever tier and four Pro editions. It runs in any modern browser on desktop, tablet, or phone. The free tier ships seven classical repertories (Kent, Boericke, Boenninghausen's Therapeutic Pocketbook, Hering's Guiding Symptoms, Boger's Synoptic Key, Ward's and Roberts' Sensations As If), 12+ classical materia medica titles (Kent, Boericke, Clarke, Allen's Keynotes, Hering, Boger, Lippe, Paterson and more), AI-powered semantic search across both repertory and materia medica, and a complete, simple-to-use case management system. Every Pro tier (Base, Murphy, Complete, Saine) unlocks the full AI suite (Notes-to-Rubric extraction, AI Case Analysis, live audio consultation transcription, AI Photo Analysis), Jan Scholten's full materia medica series (Elements, Lanthanides, Minerals, Mosses, Ferns, Qjure, Wonderful Plants — 7 modern MM books), Materia Medica Search, the Periodic Table, and unlimited cases. Up to seven premium repertories are available across the Pro ecosystem — pick the matching edition for Murphy's MetaRepertory (Pro Murphy), Complete Repertory 2026 (Pro Complete), or Saine Repertory 2025 (Pro Saine); Pro Murphy also bundles Murphy's Nature's MM 4th ed. Add Suggesta 2.1, Qrep5, Mangialavori 100 MM and other extensions as one-time add-ons, bringing the total available modern materia medica to 12+ titles.
Pricing is published on the Similia pricing page: Free, Pro Base $19.99/mo, Pro Murphy and Pro Complete $29.99/mo, Pro Saine $26.99/mo, all with a 14-day free trial. For an overview of the free tier's reach, see the free homeopathic software page.
Side-by-side comparison
Pricing
Complete Dynamics uses a subscription model on top of a free baseline:
- Browser Edition — Free, lifetime
- Practitioner Edition — €19/month
- Master Edition — €28/month
Subscription periods from 6 months up to multi-year terms are advertised on completedynamics.com, and students receive reduced pricing on the Practitioner Edition. Repertory and materia medica add-ons (e.g. Saine Repertory 2025) are sold separately on top of the base subscription.
Similia is transparent on .com: Free, Pro Base $19.99/mo, Pro Murphy $29.99/mo, Pro Complete $29.99/mo, Pro Saine $26.99/mo, with optional one-time add-ons like Suggesta 2.1 ($299.99), Qrep5 ($99.99), and Mangialavori 100 MM ($119.99).
The honest comparison is Complete Dynamics Practitioner (€19/mo, ~€228/year) against Similia Pro Base ($19.99/mo, ~$240/year): broadly equivalent monthly cost. Pro Base unlocks the full Similia AI suite (semantic search across repertory and MM, Notes-to-Rubric, AI analysis, live audio transcription, AI Photo Analysis), Jan Scholten's full materia medica series, the Periodic Table, Materia Medica Search, and unlimited cases — on top of Free's 7 classical repertories and 12+ classical materia medica titles. Premium repertories are added by picking the matching Pro edition (Pro Murphy or Pro Complete at $29.99/mo, Pro Saine at $26.99/mo) or via one-time add-ons (Suggesta 2.1 at $299.99, Qrep5 at $99.99). Complete Dynamics gives you the Complete Repertory in extraordinary depth, rule-based analysis, and a desktop-first workflow — but no AI of any kind.
Repertories
Complete Dynamics is built around the Complete Repertory — Roger van Zandvoort's modern synthetic repertory. The Browser Edition gives free access to the entire Complete Repertory; that alone makes it one of the most generous free homeopathy resources available. The Practitioner and Master editions don't add other repertories by default but make the Complete Repertory's depth more workable through analysis and case management features. Add-on bundles like Saine Repertory 2025 and other repertory / materia medica extensions are sold separately on top of the subscription.
Similia ships 14+ repertories across Free + Pro: 7 classical on the free tier (Kent, Boericke, Boenninghausen, Hering, Boger, Ward, Roberts) and 7 premium on Pro (Murphy's MetaRepertory, Complete Repertory 2026, Saine Repertory 2025, Suggesta 2.1, plus other extensions). Every repertory is searchable in parallel through the same semantic search bar — no need to switch books to triangulate.
For practitioners whose entire workflow centres on the Complete Repertory, Complete Dynamics is the natural home — you're using the author's own software. If you prefer to triangulate across Kent + Boenninghausen + Murphy + Complete in the same workspace, Similia is the broader and more flexible option. If you want to understand which repertory matches your style, our Murphy vs Kent vs Complete Repertory guide goes deeper.
Materia medica
Complete Dynamics' Practitioner and Master editions include "many materia medica books," per the developer's marketing materials, with extensions available as paid add-ons. Specific titles aren't enumerated on the public homepage; the materia medica library is positioned as a supporting resource for repertorisation rather than the primary draw.
Similia's materia medica is itemised and large in both directions. Free gives you 12+ classical titles — Kent, Boericke, Clarke, Allen's Keynotes, Boger, Hering's Guiding Symptoms, Lippe, Paterson and more. Every Pro edition bundles Jan Scholten's full series (Elements, Lanthanides, Minerals, Mosses, Ferns, Qjure, Wonderful Plants — 7 modern MM books); Pro Murphy also bundles Murphy's Nature's MM 4th ed. Suggesta 2.1, Mangialavori 100 MM, Qrep5 and other modern materia medica are available as paid add-ons, bringing the total available to 12+ modern titles. AI semantic search across the materia medica lets you search every loaded source at once in natural language — not just by remedy name or rubric.
If your daily reference reading is Scholten or Murphy, Similia is more directly aligned. If you primarily cross-check against Clarke or Boericke, both work fine — but Similia's MM search is structurally more powerful.
AI
Complete Dynamics has no AI features. The Master Edition's "differential diagnosis" and "remedy suggestion" are rule-based analytical aids — they score rubrics and remedies after you've selected them. The official completedynamics.com site does not advertise semantic search, large-language-model symptom extraction, AI consultation transcription, or AI photo analysis at the time of writing.
Similia is built around AI from the ground up. The five AI features available are:
- Semantic search across the repertory — accepts natural-language symptom descriptions ("a tight band squeezing my temples") and surfaces matching rubrics across every loaded repertory. No need to know which book uses "constriction" vs "pressing" vs "as if a band."
- Semantic search across the materia medica — search every loaded MM source at once in plain language; cross-references and clinical pictures surface without manual book-flipping.
- Notes-to-Rubric — paste consultation notes and let AI extract symptoms and propose matching rubrics for review.
- AI Case Analysis — once a case is built, AI suggests differential remedy lines and flags symptoms that statistically discriminate the candidates.
- Live audio transcription — capture a consultation in real time, get a structured transcript, and have symptoms auto-mapped to rubrics. Add AI Photo Analysis for tongue, skin, and lesion photos.
This is the most material practical difference between the two products. Complete Dynamics is excellent at scoring rubrics and remedies after you've selected them; Similia's AI helps you find, translate, and capture symptoms from natural patient language — saving 10–15 minutes per consultation. That difference matters most for busy expert practitioners running back-to-back cases.
Patient case management
Complete Dynamics includes case management in the Practitioner and Master editions. Cases live on your local machine; cloud sync is not the primary model, though mobile companion apps allow some cross-device viewing.
Similia ships a complete, simple-to-use case management system that's cloud-first by design. Cases are encrypted in transit and at rest, synchronised across all your signed-in devices, and accessible from any modern browser. The interface is built so a new student can record a first case end-to-end without training, while still giving experienced practitioners full control over rubric weighting, case history, follow-ups, and analysis. GDPR compliance and HIPAA-ready handling are documented in our HIPAA & GDPR compliance guide.
Platform & devices
Complete Dynamics is one of the very few homeopathy applications with native Linux support, alongside Windows and macOS. iOS and Android companion apps extend mobile use. Internet is not required to use the desktop edition.
Similia runs in any modern browser. There is nothing to install, no driver to manage, no platform-specific bug surface. iOS, Android, ChromeOS, Linux, Windows, macOS — all the same.
Support & community
Complete Dynamics is a small-team product with a strong reputation among practitioners who value the Complete Repertory specifically. Support runs through email and regional dealers; updates and bug fixes are included with the active subscription period.
Similia provides email support, an evolving knowledge base, and direct contact with the founding team. The Hompath Zomeo vs Similia comparison covers another angle on community and migration.
Updates & roadmap
Complete Dynamics ships incremental updates inside each subscription cycle; the Complete Repertory itself is updated by Roger van Zandvoort directly. Free upgrades and support are included for the active subscription period.
Similia ships continuously — repertory updates, AI improvements, and UI polish land in production weekly without a manual upgrade step.
When Complete Dynamics is the better choice
Be specific about the wins:
- Your practice centres on the Complete Repertory specifically. You're using software written by the repertory's own author — there's no closer fit.
- You use Linux, or strongly prefer native desktop apps. Complete Dynamics is one of the only homeopathy programs with a real Linux build.
- You work entirely offline. The desktop edition runs without an internet connection. Useful for rural or low-connectivity settings.
When Similia is the better choice
- You want native AI tools — five of them. Semantic search across repertory and materia medica, Notes-to-Rubric extraction, AI Case Analysis, live audio transcription, and AI Photo Analysis. None of these are part of Complete Dynamics.
- You're a busy expert practitioner. Live transcription + auto-mapping saves 10–15 min per consultation; Photo Analysis turns a tongue picture into rubrics in seconds. The volume payoff scales with caseload.
- You want to triangulate across multiple repertories in one place. Similia's free tier alone includes seven classical repertories, and Pro adds seven more. Complete Dynamics centres on one (the Complete Repertory).
- You work across devices. Cases need to follow you to a tablet on a home visit, then back to a laptop in the office, without a manual sync step.
- You want a deeper free tier. Complete Dynamics' Browser Edition gives you the Complete Repertory free; Similia's free tier gives you Kent, Boericke, Boenninghausen, Hering, Boger, Ward, Roberts, plus 12+ classical materia medica titles plus AI semantic search.
FAQ
Is Complete Dynamics free?
Yes, partially. The Browser Edition is free for life and gives full access to the Complete Repertory with search and browse. Case management, analysis, materia medica, and the differential-analysis features require the paid Practitioner Edition (€19/mo) or Master Edition (€28/mo). Similia's free tier is differently structured: it includes seven classical repertories, 12+ classical materia medica titles, AI semantic search across both, and a complete case management system at no cost — and never expires.
Can I switch from Complete Dynamics to Similia?
Yes. There is no automated case-import path — Complete Dynamics' case data lives in a proprietary local format — but the case template structure is conceptually compatible. Most practitioners migrate active cases manually and keep the Browser Edition installed alongside Similia for fast Complete Repertory lookups in the early months. If you've also looked at the Vithoulkas Compass, see our Vithoulkas Compass vs Similia comparison for a similar migration story.
Does Complete Dynamics have AI features?
No. Complete Dynamics does not advertise AI of any kind on its public website. The Master Edition's "differential analysis" and "remedy suggestion" features are rule-based analytical aids — they score rubrics and remedies you've already selected. There is no semantic search, no large-language-model symptom extraction, no consultation transcription, and no photo analysis. Similia ships semantic search across both repertory and materia medica, Notes-to-Rubric, AI Case Analysis, live audio transcription, and AI Photo Analysis as native features.
Which has more repertories?
Complete Dynamics is centred on a single very deep repertory — the Complete Repertory — with 2.3 million remedy additions across 206,000+ rubrics. The Saine Repertory 2025 and other repertories are available as paid add-ons. Similia ships 7 classical repertories on Free + 7 premium repertories on Pro (14+ total), including the Complete Repertory 2026 on the Pro Complete edition, and lets you compare and combine across them in a single AI semantic search.
Which is better for students?
It depends. If your school teaches with the Complete Repertory, Complete Dynamics' free Browser Edition is unbeatable — it's the author's software, free, and gives you the full repertory. If your school teaches Kent, Boenninghausen, or a more eclectic mix, Similia's free tier gives you those repertories plus AI semantic search at no cost. Many students start with both: Complete Dynamics Browser for the Complete Repertory, Similia for everything else and case management.
Verdict
Complete Dynamics and Similia are both unusually generous to free users and overlap less than their feature lists suggest. Complete Dynamics is the right answer if your practice or school revolves around the Complete Repertory and you specifically want a native offline desktop application (Linux included). Similia is the right answer for the much larger group of practitioners — students, mobile-first practitioners, AI-curious clinicians, and busy expert practitioners — who want a multi-repertory AI-assisted workspace, complete cloud-synced case management, and a free tier that already includes 7 classical repertories, 12+ classical MM titles, and AI semantic search.
For most practitioners getting started, install both free tiers and spend a week using each. Try Similia's free homeopathic software for AI semantic search across seven classical repertories, and Complete Dynamics' Browser Edition for the Complete Repertory itself. You'll know within days which workflow fits your style. And if you want to widen the field, the best homeopathic software 2026 roundup compares five tools side by side.
