The Homeopath's Guide to Repertory Apps: Which One Is Right for You?

By Leah Bugg, LHP, CHP | Rubric Wise

If you are anything like me, you find yourself thinking about cases and needing to repertorize on the go. The good news is that you have several options for a repertory in your pocket, and many of the best homeopathic tools available right now are completely free. Anyone can get started today.

Whether you are a home prescriber wanting to feel more confident with acute prescribing, a student building your repertory skills, or a practitioner who wants reliable tools on the go, there is something in this list for you. And right now, in early 2026, the landscape for mobile repertorizing is genuinely exciting. A new app just dropped that the homeopathic community has been waiting for. More on that shortly.

First: Know Your Stage

The best app for you depends on where you are in your homeopathic journey.

Home prescribers need something that speaks plain language, is easy to navigate without training, and helps with the most common acute situations. You do not need the full classical repertory yet. What you need is confidence and clarity to begin.

Students in formal training benefit from a proper repertory with full classical structure and the ability to save and revisit their analyses. The goal is not just to get an answer, it is to develop the skill of navigating the repertory well. That takes a tool that reflects how the books actually work.

Practitioners need robust case management, multiple repertories, and the ability to work seamlessly across devices without disrupting their clinical flow.

Keep your stage in mind as you read, and notice how many of these tools have a free version. The barrier to getting started has never been lower.

The Apps

For Home Prescribers: Start Here

Homeopathy at Home App (minimal one time app fee, I believe) iOS and Android | Works offline

This app was created by Mary Greensmith of Homeopathy 247, specifically to help families prescribe safely and confidently at home. It covers 100 of the most commonly used remedies for first aid situations, with clear symptom descriptions in plain language and practical guidance on potencies and dosing. It works fully offline, which makes it genuinely useful when you have no signal.

The app is clear, well-organized, and confidence-building. This is the app to recommend to clients who want to feel more equipped between appointments, or to anyone just discovering homeopathy and wondering where to start. It also has a companion version for dog owners.

To extend your learning further, Mary also runs the Homeopathy Learning Studio, which offers courses and monthly webinars. You can access the platform with 50% off using my code LEAHB50HLS.

ABC Homeopathy Remedy Finder Free | Browser-based, no download needed | abchomeopathy.com

A browser-based remedy finder with a database of nearly 1,000 remedies and over 65,000 symptoms. You tick symptoms by category and body region, and the tool surfaces potential remedies in a grid. There is also an active community forum where you can read about others' experiences.

No classical rubric structure, no case management, no grading. But it requires nothing to get started: no download, no account, just open your browser. For the genuinely curious beginner, it is an accessible front door into the world of homeopathic prescribing.

For Students: Build Your Skills Here

Oorep (Open Online Repertory) Free, always | Browser-based, no account needed | oorep.com

Oorep was built by a physicist who loved homeopathy and could not access affordable electronic repertorization. He built it himself, made the source code open, and offers it free of charge.

It includes Kent, Boger, and Hering. The interface is clean and minimal: search a symptom, browse rubrics in their classical hierarchy, add to your analysis, repertorize. Wildcard searches work (type 'cough*' to surface all related rubrics), and you can narrow results by excluding terms. No login, no installation, works on any browser including mobile.

There is no Materia Medica, no case saving, no AI. What it offers is a clean, free way to learn how rubrics are structured and practice navigating them before investing in paid software. Use it as a study companion and cross-reference tool.

Similia Free tier (permanent, not a trial) + Pro subscription (with free trial to pro) | Web platform plus mobile app, seamless across both | Similia.io

This is the most important tool on this list for anyone serious about their repertory work, and the fact that the free tier is genuinely functional makes it even more significant.

The biggest practical advantage is how it works across devices. Start a case in your browser, pick it up on your phone between sessions, finish it on a tablet. Everything syncs automatically. This is the missing link we needed for our fast-paced lives. For practitioners who move between settings, or students who study in different places, that seamlessness is a genuine game changer.

The free tier is not a stripped-down preview. It includes the classical repertories (Kent, Boericke, Boenninghausen, and more), classic Materia Medica, case management, and something worth highlighting: semantic search is included at no cost. You can type a symptom in everyday language rather than needing to know the exact classical term, and Similia maps it to relevant rubrics in the classical repertories. That removes a real barrier for those not yet acquainted with the 230-year-old repertory language and structure of Kent's time.

Pro adds AI photo and notes analysis, unlimited cases and analyses, an interactive periodic table of elements for remedy relationships, and premium Materia Medica search. Premium repertories including Murphy, the Complete Repertory, and the Saine edition are available as additional monthly add-ons and other repertories such as Mangialavori’s Suggesta and Sherr’s Q-Rep for a one-time fee. The monthly subscription means no large upfront purchase and no long commitment. You can start, test it properly, and scale your access as your practice grows.

I personally use and love Similia. It has been a welcome addition to my practice and I reach for it daily when I am on the go.

The free version is worth signing up for today. When you are ready to go Pro, use code RUBRICWISE for 10% off.

Affiliate disclosure: I use and genuinely recommend Similia. This is an affiliate link — if you upgrade to Pro, I may earn a small commission at no extra cost to you.

For Practitioners: The New Arrival Worth Your Attention

Opus Go Free version available + Premium Bundle | iOS and Android | Opusgo.app

This is the latest news in the homeopathy repertory app world.

Opus Go was just released by Zeus Soft, a Belgian company with over four decades in homeopathic software development, and it has arrived with one feature that changes the conversation for professional mobile repertory work: the Synthesis Adonis Repertory on a phone.

If the Synthesis App name rings a bell, that is because it was the previous mobile offering — a standalone app that gave users access to the Synthesis repertory on iOS and Android. Opus Go is its successor, rebuilt from the ground up with a more modern interface, expanded functionality, and a flexible access model. If you were using the old Synthesis App, this is what comes next.

Until now, if you used the Synthesis Adonis as your primary repertory, you were largely tethered to your desktop. Opus Go ends that. It is the only mobile app to include the Synthesis, and for anyone who prescribes from it daily, having it fully functional in your pocket is a meaningful shift in how you can work.

A free version is permanently available and gives you real access to explore the app and core repertory functionality before committing to anything. This is not a demo. The Premium Bundle unlocks the full repertory library and the option to add individual repertories, such as Luke Norland's Thematic Repertory, for a small additional annual fee.

Beyond the Synthesis itself, the app is built for clinical speed: intelligent search, side-by-side document display, patient manager, saved analyses, and backup and restore. Light and dark mode. Available in eight languages.

For practitioners who also use RadarOpus on desktop, you can export your cases from Opus Go and upload them into RadarOpus to continue your analysis. So there is a mobile-to-desktop workflow.

This app is newly released and I am still exploring it. I will be sharing a more in-depth look as I spend more time with it — so if you want to know what it is actually like to use in practice, get on the Rubric Wise newsletter and I will bring it to your inbox. Opus Go deserves your attention right now.

Hompath Firefly Desktop and mobile app | Hompath.com

Hompath Firefly includes 10 repertories, over 100 volumes of Materia Medica and clinical books. I have been using this app for a long time and genuinely value the remedy properties, the Materia Medica depth, and the access to classic authors. It does have a repertory function, though I have found it a little more challenging to navigate on a phone than some of the newer apps. You can find a more detailed review of Firefly over on my Instagram here.

The Materia Medica breadth is hard to match at this price: Sankaran, Clarke, Allen, Hering, Tyler, Nash, and more, with over 100 cured cases from Kent and other masters all included. For students who want a rich reference library they own outright, this remains excellent value. I use this app daily for these references, though much of this Materia Medica content is now also emerging in the newer platforms like Similia and Opus Go.

Quick Reference

Where to Start

If you are a home prescriber: download the Homeopathy at Home app today. It works offline and will start building your confidence immediately. When you are ready to take it further, Similia's free tier is your next step - a gentle way to begin familiarizing yourself with the classical structure of Kent and others.

If you are a student: Sign up for Similia Free. Use it alongside Oorep for classical cross-referencing. Between the two, you have everything you need before investing in paid tools. When you are ready to go deeper, my Similia discount code gives you 10% off your monthly subscription for as long as you are subscribed. You can move between the free and paid plan at any time and never lose your case notes - which is a genuine game changer in itself.

If you are a practitioner: Similia and Opus Go just changed the mobile landscape. Try the free versions and see whether having these tools in your pocket is as useful as it sounds. For most of us, the answer will be yes.

Whatever your level: the apps are a tool. The right one clears the way for your clinical reasoning. It does not replace it. You are the prescriber, and your clinical experience backed by knowledge of Materia Medica is what brings your repertorizations and ultimately your remedy decisions to life.

Stay in the Loop

Opus Go just launched. Similia is continually updating and adding new features. The tools are changing, and AI tools will continue to influence online resources. I will be covering app walkthroughs, honest comparisons, rubric guides, and practical resources to help you prescribe with more clarity and confidence.
