Free 3D Anatomy Apps in 2026: anotemy, BioDigital, and More

How we picked

We checked each app's own pages on 2026-10-26. Free means a free plan you can keep using, open source, or a time-limited trial that gives you full access for a few days. We also counted free downloads that gate most content behind a subscription.

We make anotemy, a web app that is free while in beta. anotemy turns typed anatomy terms into 3D views inside your notes: type “rotator cuff” and a 3D model of the back appears with the rotator cuff lit orange. You can draw on the page, add boxes and arrows, and drop in slide PDFs.

• Free plan with monthly caps: BioDigital's Personal plan gives 10 model views per month.
• Open source, no paywall: Z-Anatomy is free for everything, including the Blender template.
• Free model repository: NIH 3D offers free downloads and a web viewer, but no guided curriculum.
• Trial only: Complete Anatomy offers a 3-day free trial; no permanent free tier.

The apps

Here are the apps we compared, what you get for free, and the catch. We ordered them by how much you can do without paying, from fully free to trial-only.

• anotemy: Free while in beta; runs in a modern browser on laptop, desktop, or iPad (no native iPhone or Android app). Type a structure name and the word lights up: brain regions underlined violet, body structures orange; tap to open in 3D. Best for students who want anatomy inside their own notes, with drawing, PDF slides, and quizzes.
• Z-Anatomy: Everything is free and open source (CC BY-SA 4.0); web app, Blender template, and Windows build. Main limit: rougher interface and possible content gaps (2022 coverage noted missing lymphatic system, current status unverified). Best for makers and students who want a remixable atlas.
• NIH 3D: Free to browse, view, and download models (GLB, STL) from the U.S. NIH. It is a model repository, not a guided atlas: no labels, curriculum, or quizzes. Best for getting printable or viewable anatomy models for projects.
• BioDigital Human: Free Personal plan gives male and female anatomy, 500+ A&P models, and Human Studio, but caps usage at 10 model views per month and 5 saved models. Runs on web, iOS, and Android. Best for occasional look-ups and short guided tours, not daily study.
• Zygote Body: Lite plan is $0/month and includes complete male and female anatomy, but the comparison table only covers paid plans, suggesting Lite is ad-supported (unverified). Web only. Best for quick browser look-ups with no install.
• Anatomy Learning – 3D Atlas: Free download includes part of the content; the Definitive Edition (all content and features) is a one-time $16.99 on the US App Store. Available on iOS, Android, and web (WebGL 2). Best for a cheap one-time phone atlas with dissection layers and quizzes.
• Visible Body Suite: No free tier for the Suite; the app is a free download but requires a subscription. There is a free Learn Site and free flashcard decks listed, but full dissection and quizzes need a paid plan ($34.99/year student). Available on web, iOS, Android. Best as a low-cost paid atlas for A&P courses.
• Complete Anatomy: No permanent free plan; only a 3-day free trial with no payment details required. After that, Student plan is $74.99/year (first-year discount $39.99 on web store). Native apps for iPad, iPhone, Mac, Windows, Android; web for institutional subscribers only. Best for students who want deep dissection tools and will pay.

What's really free

Here is a clear breakdown of what each app actually gives you without payment, along with the main restrictions and the platforms you can use it on. The table covers only the free offerings as verified on 2026-10-26.

Which one should you pick?

Your choice depends on how you want to use 3D anatomy. Consider these common situations.

• You want the most detail for free: Choose Z-Anatomy. It gives you the complete open-source 3D atlas with layers for skeleton, muscles, vessels, nerves, and organs, all for free and usable offline through the Blender template or Windows build. The trade-off is a rougher interface and possible content gaps (the lymphatic system was missing as of 2022, though current status is unverified). If you prefer a smoother, guided experience without paying, BioDigital Human's free plan gives 500+ anatomy and physiology models, but the 10 views per month cap makes it only for occasional look-ups. anotemy also offers free 3D views of 76 brain regions and 6,800 body parts, but it is a note-taking tool, not a full dissectible atlas, so it lacks the depth of layer-by-layer dissection found in Z-Anatomy or paid apps like Complete Anatomy.
• You want to take notes with 3D: anotemy is the only free app that combines typed notes with interactive 3D anatomy. Type a structure like "hippocampus" or "rotator cuff" and the word lights up; tap it to open that structure in 3D right above your text. You can embed a 3D view as a picture in your note, draw with a pen, mouse, or Apple Pencil, drop lecture slides as PDFs, and quiz yourself on structures. Other apps let you annotate the 3D model itself, but not within a notebook: Complete Anatomy has sketch tools on the model, Visible Body has 3D Draw, and BioDigital lets you draw on a 2D snapshot, but none offer a free-form text notebook. anotemy runs in a browser on laptop, desktop, or iPad, and your notes sync across devices when you sign in with Google or Apple.
• You're on a phone: anotemy has no native iPhone or Android app, so it is not ideal for phone-only study. BioDigital Human has native iOS and Android apps with the free plan, but the 10 views per month limit is very tight for daily phone use. Anatomy Learning – 3D Atlas is a solid choice: it offers a free download with part of the content, and a one-time purchase of $16.99 gives you the Definitive Edition with full content and features, though the free portion is not clearly documented. Visible Body Suite's free Learn Site works in a mobile browser and offers introductory 3D models, but the full dissectible atlas needs a subscription. If you have a school licence for Complete Anatomy, its phone app is excellent, but without a licence you only get a 3-day trial.
• Your school pays for a license: If your institution provides Complete Anatomy Student Plus or Faculty, use that first. It offers the deepest dissection tools, cross-sections, radiology images, and guided courses, and the institutional licence includes web access. Visible Body Courseware is common in courses where instructors assign quizzes and flashcards, and it comes at a lower institutional cost. BioDigital's School or Institution plans let faculty embed 3D models and quizzes in an LMS, but individuals on those plans get unlimited views within the class, unlike the free personal plan. Even with a school licence, keep anotemy or Z-Anatomy as free complements for note-taking or open-source study, since they remain available at no cost after the school year ends.
