Type "homoeopathic repertory software free download" into Google and you enter one of the stranger corners of the homeopathy internet: forum threads from 2009, file-sharing mirrors offering a 250 MB setup.exe of software last updated when Windows 7 was new, and "full version + crack" listings for packages that cost hundreds of euros. This guide is the practical answer to that search — what is actually free and legal, repertory by repertory, and how to get a complete repertorisation program running on your PC in under a minute without downloading anything at all. (As with everything on this blog, it is written for practitioners and students, not as self-treatment advice for the public.)
The short version: the classical repertories are public domain and legitimately free — you just don't need an installer to use them any more. The modern repertories are copyrighted and never legally free. And the "download" itself is the obsolete part: modern repertory software runs in the browser, installs from it in one click, and keeps itself up to date.
What a "free download full version" actually gets you
It is worth being blunt about what sits behind those links, because a practice computer is the worst possible place to run them:
- Abandonware. Genuinely free desktop programs from the 2000s still circulate. They run — sometimes — on modern Windows, but the remedy data is frozen at whatever their author last compiled, there are no security patches, and no export path for your cases when they finally stop working.
- Pirated commercial packages. "Full version" almost always means an unlicensed copy of RadarOpus, Hompath or similar, typically an edition several revisions old. Beyond the legal problem, cracked installers are a classic malware vector — and a machine that holds patient records is precisely the machine you should never run one on.
- PDF scans. Kent's print repertory as a searchable PDF is legal (the text is public domain) and useless for actual repertorisation: a PDF cannot add rubrics to a case, weigh grades, or tabulate remedies. It is a book, not software.
None of this is what the search is really after. What you want is a complete, current repertory you can search and repertorize with, at zero cost, on your own computer. That exists — it just stopped being a download.
The dividing line: public domain vs. copyrighted repertories
Every question about "free repertory software" reduces to copyright, so here is the map:
Legally free (public domain): Kent's Repertory, Boericke's Repertory, Boenninghausen's Therapeutic Pocketbook, Hering's Guiding Symptoms, Boger's Synoptic Key, and the classical "Sensations As If" collections of Ward and Roberts. Anyone may digitise and serve these complete. Similia includes all seven free forever — as structured, searchable repertories wired into a repertorisation engine, not as page scans.
Never legally free (copyrighted): Murphy's MetaRepertory, Roger van Zandvoort's Complete Repertory, Frederik Schroyens' Synthesis, André Saine's repertory, and every other actively maintained modern work. The continuous editorial revision is the product. These are licensed — in Similia, as premium editions layered on top of the free classical library — and any site offering them as a free download is offering piracy.
That single distinction answers most of the named searches, so let's take them one by one.
Kent repertory software free download
Kent is public domain, and the complete repertory — 68,000+ rubrics with gradings — is included in Similia's free tier. Open the app, search any rubric in plain language or chapter order, add it to a case, and tabulate. Nothing to download, nothing to pay, no trial that expires. If you are studying how the book itself is organised — chapters, rubric hierarchy, gradings — the guide to Kent's repertory structure walks through it.
Complete Repertory software free download
The Complete Repertory is Roger van Zandvoort's life work and has been continuously revised since the 1980s — the current edition is Complete Repertory 2026. It is copyrighted, so there is no legal free download and there never has been; old pirated copies miss two decades of additions, which defeats the point of using the largest modern repertory at all. In Similia it is available as the premium Complete Edition, on top of the seven free classical repertories, with a 14-day trial. What the Complete Repertory actually contains — and how it differs from Kent — is covered in its own guide.
Synthesis repertory software free download
Synthesis (Schroyens) is the repertory of the RadarOpus ecosystem and is not licensed to any other platform — no legal free download exists, and the "Synthesis App" is a paid product of the same publisher. If Synthesis specifically is what you trained on, RadarOpus is where it lives. If what you need is a large modern repertory rather than that specific one, the Complete Repertory 2026 and Murphy's MetaRepertory occupy the same clinical role and are available in Similia without desktop software. The Synthesis repertory guide covers its editions, structure and access options in detail.
Murphy repertory software free download
Murphy's MetaRepertory (4th edition) is copyrighted, current, and clinically organised — alphabetical chapters, modern symptom language. No legal free copy exists. In Similia it is the premium Murphy Edition, paired with Nature's Materia Medica 4th edition, and it runs entirely online in the same interface as the free classical library.
"For PC": running a full repertory on your computer without an installer
The desktop experience the download-seeker wants — an icon, its own window, fast startup, works at the desk with patients — no longer requires a setup file. Similia is a progressive web app: on Windows, open it in Chrome or Edge and click Install in the address bar; on a Mac, the same from Chrome, or add it from Safari. The app appears with its own icon and window like any installed program, and because updates ship on the server, it is never version 2.3 waiting for a DVD upgrade.
Phones and tablets install the same way — the step-by-step install guide for Android, iPhone and desktop covers each platform in a minute apiece, including an honest section on what works offline and what needs the connection: live rubric search, materia medica lookups and case sync all require the server, so a fully offline practice remains the one constraint where a classical installed program is still the right tool.
One genuine advantage of the no-download model is worth naming for anyone keeping patient records: a cracked or abandoned installer never sees a security patch, while a cloud platform patches continuously and keeps records off any single hard drive. How Similia handles GDPR and HIPAA compliance — encryption, EU hosting, data-processing agreements — is documented separately.
What "free" includes, precisely
Free-forever, no card, no expiry — the free plan is a working classical practice setup, not a demo:
- Seven classical repertories, complete: Kent, Boericke, Boenninghausen's Therapeutic Pocketbook, Hering's Guiding Symptoms, Boger's Synoptic Key, and Ward's and Roberts' "Sensations As If"
- 13 classic materia medica books — Kent's Lectures, Boericke, Clarke, Hering, both Allens, Boger, Lippe, Nash and Paterson — in the built-in materia medica software
- AI semantic search that finds rubrics from everyday symptom language
- Basic case management, capped at 3 new cases and 3 analyses per month
The premium tiers exist for what is genuinely licensed or costly to run: Murphy's MetaRepertory, Complete Repertory 2026 and Saine 2025, the premium materia medica collections, the AI toolkit, and unlimited cases. For a hands-on comparison of how this stacks up against RadarOpus, Complete Dynamics and Hompath Zomeo — including their pricing — see the 2026 homeopathic software review.
The bottom line
"Free download" was the right search in 2005. In 2026, the legitimate free option is better than the thing being searched for: the complete public-domain repertory library, structured and searchable, wired to a repertorisation engine and a full materia medica, installed on your PC from the browser in one click — with the modern copyrighted repertories available legally, as licensed editions, in the same window. Skip the mirror sites; start with the free account and see if it does what the setup.exe never quite did.
