Decision Guide
A 2026 buyer’s guide to repertory software and newer AI tools: what you get, what you pay, and what to check before choosing.
There is no single best homeopathy software for everyone in 2026. The right choice depends on your repertories, library, devices, budget and working method. Here is how nine options compare.
The software that suits you as a student may need to grow with you into practice. You might want a familiar repertory, a larger library or help finding your way through case notes. Start with the work you want to do, then compare the books, tools and payment options that support it.
We sell RadarOpus in the UK. This is a buyer’s guide to selected products, based on suppliers’ public information checked on 21 October 2026. It isn’t an independent hands-on test, a security audit or a ranking of the whole market. Prices are shown in their advertised currencies; packages, tax and billing terms differ.
Help me compare homeopathy software
Make a short list of the books your course or practice needs, the devices you work on and the tasks you repeat most often. Then look at the products below. An installed repertory library, a browser-based case system and an AI reading assistant may overlap, but they don’t necessarily replace one another.
- For study: can you browse the repertory, inspect grades and references, and read the source text?
- For practice: can you keep, find, back up and export the records you need?
- For your budget: what is included today, and what will cost extra later?
- For AI: can you see where a suggestion came from and decide what information leaves your device?
A quick look at the main options
RadarOpus
RadarOpus combines repertory work, reference books and patient files in an installed Windows or Mac program. It is worth exploring if Synthesis is part of your study or working method. The library and software tools vary by package, so choose those together.
- Books: Essentials includes Synthesis Treasure 2009. Higher packages offer Synthesis Adonis; don’t assume the entry-level Core package includes Synthesis.
- Cost: UK advertised purchases are £375 for Core, £750 for Essentials, £1,500 for Advanced and £2,250 for Optimum. The UK package guide says prices include UK sales tax.
- Check: lifetime licensing doesn’t cover every possible future upgrade, support session or replacement activation. Read the current licence terms and ask about moving to another computer.

Synergy Viva, formerly SHS
Synergy Viva is the current relaunch of SHS. Its library and repertory tools include searches across books and ways to compare references. Reliable Repertory is included in the entry-level offer. Optional modules add other methods and tools, including the Genie AI assistant.
- Books and cost: the edition comparison lists a Student subscription and lifetime Foundation, Professional and Visionary editions. Ask for a current quote and book list; some edition pages contain conflicting wording about the licence period.
- AI: Genie is listed at $500, with usage tokens bought separately after the starter allowance. Its “lifetime” feature access does not mean unlimited AI questions. Confirm currency and tax with your representative.
- Check: Viva has current Windows and Mac requirements. Ask which core features work offline and how the licence checks in; Genie uses an external AI service.
Vithoulkas Compass
Vithoulkas Compass is an online system built around George Vithoulkas’s approach. It combines its Kent-based repertory with guided analysis tools, case histories and follow-ups. It is a useful option to explore if that method is central to your work and you want browser access across devices.
- Cost: subscriptions include credits for specified expert-system actions. Extra packs are available. Check the current price for your country and the number of analysis actions you expect to use.
- Check: credit rules affect which actions use credits and what carries over. Ask about expiry, renewals and access to records after the subscription ends.
- Patient information: its terms prohibit identifiable patient details. Read the case-entry rules before trying it with real material.
You may also come across VithoulkasBrain, a newer expert system associated with the same teaching tradition. Treat it as a separate product enquiry. It has its own operator and patient-data agreement; don’t assume that a Compass subscription, case file or privacy agreement transfers across.
Complete Dynamics
Complete Dynamics centres on Complete Repertory, with repertory browsing, analysis, case files and materia medica. It offers a free Browser Edition and paid Practitioner and Master editions. Despite its name, Browser Edition is part of the installed program, rather than an online-only service.
- Cost: the current price list shows Practitioner at €19 for one month or €191 for a year, and Master at €29 for one month or €287 for a year. Longer terms are discounted. Tax and the final local quote need checking.
- Included: its licence page says subscriptions include program and Complete Repertory updates and technical support. Renewal is by choice, without automatic renewal. Extra books and translations can cost more.
- Devices: downloads cover Windows, Mac, Linux and Android; iOS is bought separately. Master’s additional editing and analysis tools are desktop-only.
Hompath Zomeo
Zomeo brings together repertory work, books, patient management and named expert systems, including Tempraz. Its product page advertises Complete Repertory 2024, with other resources available as add-ons. Ask for the actual package list rather than choosing by a headline book count.
- Cost: the comparison page shows US-dollar figures of $1,500 for Zomeo and $2,500 for Ultimate. Get a written quote confirming licence duration, tax, support and update costs; those figures alone don’t establish a lifetime offer.
- Devices: Windows and Mac versions are advertised, alongside Zomeo Mobile. Confirm your exact operating system, the books in each version and whether your desktop and mobile cases can move between them.
- Check: a named expert system is not necessarily a generative AI assistant. Ask to see the particular analysis or search method you want to use.
Vision from Miccant
Vision offers a purchased desktop program with repertories and optional book collections. The important budgeting detail is that the base package does not include materia medica by default.
- Cost: Vision version 2 is listed at £389. Complete Repertory 2026 is a £300 add-on; materia medica collections are separate. Confirm tax on the invoice.
- Licence: Miccant advertises lifetime licences, but activation and occasional online checks are required. Major upgrades and extra activations may cost more.
- Check: confirm your exact computer compatibility before buying, particularly on a Mac. The current product page carries a Mac compatibility warning, and Windows support is specified for Windows 11.
Similia
Similia combines repertories, materia medica and case tools with search by meaning and optional AI features. You can also browse and choose rubrics manually. Its paid Offline Beta lets you work with downloaded material and cases, then sync later; AI features still need a connection.
- Cost: Free is available with limits. Monthly Pro prices are €16.99 for Base, €24.99 each for Murphy, Complete or Suggesta, and €22.48 for Saine. Annual billing advertises one month free; three-year billing advertises six months free. Confirm UK checkout currency and tax.
- Lifetime: the offer is $1,999 for Base or $2,999 for the bundle. Base instalments of $199 × 12 total $2,388. It includes 1,000 AI credits once, with more costing extra.
- Check: lifetime access lasts while the service is provided. A publisher’s withdrawn work can become unavailable. This is a different promise from owning independent copies of the books.
HomAI
HomAI at homai.care is aimed at practitioners looking for a workspace that combines case discussion with classical literature and repertory searching. Its features include different approaches to generating answers: some look up literature first, while an AI-only option does not. That distinction matters when you want to check a source.
- Cost: advertised plans include Free, Basic at €12/month or €120/year, and Pro at €39/month or €390/year. Confirm billing and tax at checkout. Case and analysis allowances differ, including limits on Pro analyses.
- Check: current Pro marketing describes patient tools, while the public legal page still describes a patient-data Pro arrangement as future. Ask for the current terms and patient-data contract before entering identifiable records. The mismatch needs clarification; it does not establish unlawful processing.
- Try: use a fictional study example to check the full rubric, the source passage and the difference between an AI answer and retrieved evidence.
Homeoco
Homeoco has two audiences: Hugo/Discovery for people exploring homeopathy, and Expert for trained users. Expert includes manual searching in Boger’s Synoptic Key, AI-suggested headings and remedy comparisons. These are more than a general chat interface, but they are not the same as a complete readable library.
- Sources: its feature guide describes generated summaries based on Boericke, Clarke and Boger. Full translated source texts and further repertories are described as work in progress.
- Cost: Expert advertises €10 excluding VAT per month or €100 excluding VAT per year, with a free first month. Confirm the trial’s payment timing and applicable VAT at checkout.
- Use: its terms limit the service to education, prohibit personal third-party information and prohibit assistance with diagnosis or prescribing for a specific person. Assess it as a study tool within those limits.
What’s good value over five or ten years?
Paying once can be attractive when you know which library you want to keep using. A subscription asks less of your budget at the start and may include updates. The fair comparison is the total for the books and tools you need, including tax, renewals, extra AI use and any later upgrades.
Monthly payments add up, but longer billing periods can make a substantial difference. These examples use the displayed rates without price changes or extras. Homeoco’s figures exclude VAT; confirm any additional tax for Complete Dynamics. They compare ways to pay for the same product, not the value of one library against another.
| Product | 12 monthly payments | Annual payment |
|---|---|---|
| Complete Dynamics Practitioner | €228 (€19 × 12) | €191 |
| Homeoco Expert, excluding VAT | €120 (€10 × 12) | €100 |
Complete Dynamics also lists a five-year Practitioner offer at €573. Similia Base would total €611.64 over three years paid monthly at €16.99, while its three-year billing rule gives €509.70 at that rate. Check the final quote, including tax and extras. These are illustrations at current rates, not promises about future prices.
Don’t multiply a monthly price by ten years and call that the only alternative to buying. Equally, don’t assume a lifetime licence includes every future version, all support or unlimited AI use. Ask what happens after a computer replacement or if the service closes.
Should I choose online or offline software?
Think about where you actually work. An online system can make moving between devices convenient. An installed library can be helpful when the connection drops. Many products mix the two, so ask about individual tasks: reading books, editing records, running searches and using AI may have different requirements.
- RadarOpus: everyday offline use still involves periodic licence checks: every 30 days without a physical security key, or every 12 months with one, after initial activation.
- Complete Dynamics: its case manual describes local case work and optional cloud synchronisation. A cloud copy does not remove your responsibility for backups.
- Similia: paid offline access requires reconnection every 30 days. AI and search by meaning remain online functions; offline access is not part of the free trial.
- Compass: the offered system is online. For Viva, Zomeo and other products, ask to see the exact offline tasks and activation rules you need rather than assuming “desktop” means “never connects”.
What about phones and tablets?
A phone can be handy for reference searches, but try reading a full rubric path and comparing sources on it before making it your main workspace. Check whether a mobile purchase includes your desktop books and whether cases can be exported, imported or synchronised. Those are different capabilities.
- OpusGo: Zeus Soft’s iOS and Android app offers free Kent and reference access, patient tools and export to RadarOpus. Its Premium Bundle is advertised at €69 a year, with yearly add-ons that require Premium. Prices vary by country and tax. This is separate from a RadarOpus desktop lifetime licence.
- Complete Dynamics: Android and iOS versions are listed, but iOS is a separate purchase and Master is not available on mobile. Check current store prices and edition details.
- Zomeo: mobile editions are advertised, but don’t assume the desktop and mobile book lists match.
- Browser services: Compass and HomAI advertise access through mobile browsers; Homeoco is also an online service requiring an internet connection. Check the real experience of entering and reviewing a long case, rather than just whether the page opens.
Which should I choose as a student?
Start with your school’s reading list. Check the repertory editions and materia medica you will use throughout the course, then ask what the software includes. A free option can help you get started, but a low entry price may grow once you add the books you need. Ask about student offers, group purchases and payment plans without assuming a particular discount is available.
Our preference is to learn the repertory as a book first. Following its chapters, headings and more specific rubrics gives you something to compare a search suggestion against. You can keep building that familiarity on screen. Whichever product you choose, make time to browse beyond the results it puts in front of you.
That is a teaching preference, not proof that one program produces better practitioners. Several products here retain manual repertory work alongside newer search tools. During a trial, find one symptom yourself, then compare it with any suggested rubric. Read the complete path, check grades and references, and return to the materia medica.
What changes once I’m in practice?
Your priorities may shift towards finding old notes, recording follow-ups, comparing sources and moving safely between computers. Try those tasks in the demonstration. Ask what you can export if you leave, and whether the receiving program can actually use that export.
If you already have a substantial library, start by listing what you would gain and what you would lose by moving. A newer interface is not enough on its own. For more advanced work, check personal repertory additions, notes, family searches and the particular analysis methods you use. Pay for capabilities you can explain a use for, rather than the longest list.
How much should AI do for me?
It’s easy to see the appeal. Case notes can be complex, and the way someone describes an experience matters alongside the symptoms. Help bringing information together or finding possible connections can be useful. But a fluent answer still needs checking against the words of the case and the source material.
Search by meaning, an expert system and a chat assistant do different jobs. Search can suggest a rubric; an expert system applies its own analysis approach; a generative assistant writes a response. Ask which one you are using and what evidence you can inspect. In particular, a source-linked summary is not the same thing as reading the source.
At Zeus Soft, we want to develop these approaches carefully, with tools that stand the test of time and respect the years people spend learning their craft. The aim is to help you question and check your choices while you keep practicing the skills behind them.
RadarOpus already links to Homeopathic Philosophy Partner, an external ChatGPT-based study tool. Viva offers Genie, while Similia, HomAI and Homeoco describe other AI-assisted tasks. Compare the particular task, its sources and its data use. The label “AI” alone tells you very little about those differences.
Who looks after the patient information?
Patients trust us with very private details. Before using any service with their information, ask who receives it, where it is processed, how long copies remain and how you can remove or recover it. The responsible person may be you or the clinic you work for. Encryption matters, but so do the contract, the settings you choose and the way you work.
RadarOpus describes a locally stored encrypted patient database, with password controls that can be switched off. You still need to secure your computer and backups. Optional research uploads, cloud backups and external AI services are separate decisions about sending material elsewhere.
Cloud services can also provide contractual safeguards. Similia’s DPA, the agreement for handling patient data, prohibits model training on it by Similia and authorised providers. It addresses health-data responsibilities, outside providers and help with formal privacy assessments. It promises encryption in transit and provider storage, but explicitly not end-to-end encryption. These are documented commitments, not an independent audit.
Read the restrictions as well as the promises. Compass and Homeoco limit the personal information you may enter. HomAI’s current patient features and older legal wording need clarification. For Genie, ask about the external AI service and the terms covering anything you send. A missing public detail is a reason to ask a question, not evidence of a breach.
Neither local storage nor cloud hosting automatically establishes GDPR compliance. The ICO’s security guidance explains why the actual setup and working practices matter. Removing a name also does not necessarily make a case anonymous: distinctive details or a retained link may still identify someone. The ICO’s anonymisation guidance covers that distinction; anonymising information is itself processing that needs a lawful basis.
Synthesis, Complete, or a different repertory?
Choose by the work you need to do, the edition you are buying and the references you can inspect. Synthesis Adonis is available, but it is not included in every RadarOpus package. Complete also appears in different editions and packages across suppliers. Don’t assume a familiar title means identical content everywhere.
Other choices include Reliable, Combined, Murphy, Saine, Suggesta and classical repertories such as Kent and Boger. They need not all be substitutes for one another. In a demonstration, compare the same few rubrics, their parent headings, grades and references. Check the edition and the route back to the text. A book count, or an assertion that one repertory is “safer”, is no substitute for that inspection.
How can I try them and get help?
Use a fictional study case for an initial trial, then repeat the same tasks across your shortlist. Try browsing, searching, checking a reference, saving a case and exporting it. This gives you a better feel for the fit than watching someone else move quickly through a polished demonstration.
- RadarOpus advertises a 15-day trial. The Academy has beginner and advanced guides and recordings, with regular live training also available.
- Synergy Viva now advertises a free trial. Confirm the current duration and modules; its training library includes getting-started videos and group sessions.
- Compass advertises seven days. Complete Dynamics offers a 30-day downloaded trial and continued free Browser Edition access; iOS has no free trial.
- Zomeo’s trial page advertises 30 days, while older FAQ wording differs. Vision advertises 14 days.
- Similia has Free and an advertised 14-day Pro trial. HomAI advertises a trial in its public app; confirm the tier and limits. Homeoco Expert advertises a free month, with payment timing to check.
Ask who you can return to after the demonstration, what help is included and what costs extra. Try a training recording before committing. A supportive community and a way of teaching that suits you can matter as much as a feature you may rarely use.
Bring your shortlist, reading list and budget to that conversation. If you want to explore RadarOpus, you can ask us about a demonstration. The useful question is whether you can see yourself learning and working comfortably with the package, at a cost and under terms you understand.
