Complete Dynamics vs Similia

Complete Dynamics and Similia can ship the same repertory: Complete Dynamics is built natively around Roger van Zandvoort's Complete Repertory, and Similia's Pro Complete edition licenses Complete Repertory 2026. What separates them is everything around the repertory — offline desktop against cloud web app, flat published subscriptions against tiered editions with an AI-credits budget, and no AI at all against one of the most expansive AI toolsets in homeopathic software.

For the offline-first, single-method classical practitioner, Complete Dynamics is the better buy. For multi-device practice, AI-assisted case-taking, or a broader materia-medica stack, Similia leads.

Side-by-side

Where Complete Dynamics wins

Offline operation is the headline. Complete Dynamics installs natively on Windows, macOS, and Linux — the Linux desktop build is uncommon in this cohort — and the Practitioner edition extends to iOS and Android; once installed, every edition works with no internet connection. A practitioner in a rural clinic, on home visits beyond mobile coverage, or simply unwilling to make consultations contingent on a router, gets a reliability guarantee that no web application can match. The local case database is also the simplest possible data-control story: the archive lives as a file on the practitioner's own hardware, with no account required to open it.

Price is the second win. The Browser edition is free and includes a current, searchable Complete Repertory; the paid tiers are sold on a subscription from €8 per month with no contract and no automatic renewal, and all prices are published without a sales conversation. There is no module arithmetic, no credit metering, and no quote gate. Students get a reduced-price Practitioner edition, and a low-budget Amateur edition exists for non-professional enthusiasts. For a practitioner who wants exactly a repertory, an analysis grid, and a case file — and nothing more — Complete Dynamics is likely the lowest total-cost-of-ownership option in the professional segment.

Third, focus and language reach. The product covers classical analysis without feature sprawl, and the interface and repertory are available in 26 languages, including Hindi, Hebrew, Chinese, Japanese, and Korean alongside the main European languages. Complete Repertory itself has been translated into 14 languages.

Where Similia wins

The AI surface is the widest gap. Semantic search ships free and accepts patient-language phrasing rather than rubric vocabulary. Pro adds notes analysis with OCR upload, photo-to-rubric suggestions, Live Mode for typed notes, Live Audio Mode (Beta) that transcribes the consultation and proposes rubrics in real time, and AI-extracted case timelines. All of it is metered — 100 AI credits per Pro renewal, packs purchasable — and all of it is explicitly assistive: review suggestions before accepting them. Complete Dynamics has shipped no equivalent features and has published no comparable roadmap.

Multi-device continuity is the second gap. Complete Dynamics has editions for several platforms, but the case archive is a local database tied to each installation; synchronising cases between a home PC and a clinic desktop requires manual export and import. Similia is account-bound, so the same cases appear on any browser the practitioner signs into, with colleague sharing built into the Pro tier. For multi-site clinics and hybrid tele-practice that difference is structural, not cosmetic.

Third, the stack around the repertory. Similia's materia-medica layer spans the classic corpus on Free plus premium sources by edition and add-on (Murphy, Vermeulen, Scholten, Mangialavori, Pitt, Griffith), all searchable semantically. Boenninghausen's Therapeutic Pocketbook and the standard classics sit alongside the premium repertory rather than displacing it. A practitioner moving from Complete Dynamics keeps the Complete Repertory 2026 vocabulary on the Pro Complete edition while gaining that surrounding library.

Cost

The two pricing models suit different buyers. Complete Dynamics publishes subscription prices starting from €8 per month with no contract, no auto-renewal, and no hidden module costs; everything in a given edition is included. Similia charges $29.99 USD/mo (or $329.99/yr) for Pro Complete, with AI usage metered beyond the 100 renewal credits, and additional credit packs available to purchase.

The arithmetic is straightforward. A practitioner who never uses AI features and works on one machine will pay less on Complete Dynamics at current rates. A practitioner whose working week spans two or more devices, who uses audio transcription or notes analysis regularly, or who needs the broader materia-medica library, gets more usable capability per dollar on Similia. Neither vendor buries the numbers; start with both free entries — the Browser edition and Similia Free — before committing to either paid tier.

Which fits which practitioner

Switching from Complete Dynamics to Similia

The most common switcher scenario is a Complete Dynamics Practitioner user who wants to keep the Complete Repertory vocabulary while adding AI tools. The Pro Complete edition on Similia licenses Complete Repertory 2026, so repertory navigation feels familiar from the first session. The main friction point is case data: Complete Dynamics stores cases in a local database, and Similia accepts import only in its own format. Practitioners with a large case archive should plan a manual migration or run both products in parallel during a transition window rather than expecting a one-click switch.

The reverse switch — Similia to Complete Dynamics — is less common given the AI gap, but applies to practitioners who face persistent connectivity problems or whose national reseller offers Complete Dynamics at a significantly lower local price. In that direction, data portability is the same challenge: Similia exports are not natively ingested by Complete Dynamics' local database.

The Linux practitioner

Complete Dynamics is among the very few professional homeopathy applications with a native Linux build — no other full-featured desktop repertory application in this cohort publishes a Linux installer. Practitioners who run Debian, Ubuntu, or other distributions as their primary OS have few comparable alternatives among full-featured repertory applications. Similia is browser-based and runs in any Chromium or Firefox build on Linux, so it works on that platform, but it requires an internet connection. For Linux users with reliable connectivity the choice is open; for those working offline or on air-gapped machines, Complete Dynamics is the only practical option.

Verdict

For the offline-first classical practitioner on a single machine, Complete Dynamics ranks first. For multi-device practice and AI-assisted case-taking, Similia ranks first, and the same-repertory bridge via Pro Complete makes the trial nearly costless to evaluate.
