Evidence-checked guide for clinicians and ultrasound learners
10 Best Ultrasound Apps in 2026 (iPhone and Android)
The best ultrasound app overall is POCUS Simulator by Ultrasound Fanatic for guided scanning practice without a machine. Scanbooster is best for broad simulation volumes, Prepry is best for registry exam prep, and The POCUS Atlas is the best free image atlas.
Ownership disclosure: Ultrasound Fanatic makes POCUS Simulator, our number one pick. We disclose that relationship and evaluate every app using the same criteria, including usefulness, availability, price, platform support, and limitations.
Practice POCUS Without a Machine
Ultrasound apps fall into three different groups: simulators that teach probe-to-image thinking, learning and reference tools that teach knowledge, and companion apps that only work with a paid handheld probe. The best choice depends on what you actually need to practice.
Our quick recommendation: Choose POCUS Simulator for guided clinical cases without hardware, Scanbooster for a larger virtual scanning library, PoCUS Pocket Trainer for spatial probe orientation on iPhone, Prepry for ARDMS or CCI exam preparation, and The POCUS Atlas for a free pathology clip library. If you already own a Butterfly, Clarius, or Vscan Air probe, use that manufacturer’s companion app.

How We Evaluated These Ultrasound Apps
We checked current US App Store and Google Play availability, the job each app is designed to do, its educational value, platform coverage, pricing clarity, recency, and important limitations. Simulator, reference, exam-prep, and hardware apps were not treated as interchangeable.
A recommendation needed a current official listing or an active official mobile website. We excluded dead, unverified, and clearly abandoned options.
Each pick had to solve a clear problem, such as guided practice, image recognition, exam prep, bedside reference, or probe control.
We state when an app is iPhone-only, requires a subscription, has a smaller library, or cannot work without paid hardware.
What we excluded and why: SonoAccess was removed because we could not verify a current US App Store or Google Play listing. SonoSupport was removed because its latest listed update dates to 2014. Awesome Ultrasound Simulator was replaced because its latest listed update dates to 2020 and a more current structured-learning option is available. We do not link readers to APK mirrors.
Ranks 1 to 3
Best Ultrasound Simulator Apps (No Probe Required)
These apps simulate parts of the scanning experience or connect probe movement with the resulting image. They are educational tools and do not acquire diagnostic ultrasound images.
1. POCUS Simulator by Ultrasound Fanatic: Best for Guided POCUS Practice
POCUS Simulator is our top pick for learners who want a guided path from a clinical case to protocol selection, probe positioning, and image recognition without purchasing an ultrasound machine. The free case lets you test the teaching approach before subscribing. It is especially useful for beginners who want structure instead of an unorganized clip library.
2. Scanbooster Ultrasound Sim: Best for Diagnostic and OB/GYN Volumes
Scanbooster offers a broad mobile ultrasound simulation library with a strong emphasis on sonography, obstetrics, gynecology, and diagnostic scanning. A second device can function as a virtual probe controller, creating a more machine-like interaction than a simple image quiz. It is a strong choice for learners who prioritize volume navigation and specialty variety.
3. PoCUS Pocket Trainer: Best for Learning Probe Position and Spatial Anatomy
PoCUS Pocket Trainer connects virtual probe movement, 3D anatomy, and the resulting ultrasound view. That makes it useful for a difficult beginner concept: understanding why a small change in probe position or orientation changes the image. Choose it to build probe-to-image intuition, then pair it with clinical cases and supervised scanning.
Ranks 4 to 7
Best Ultrasound Learning, Reference and Exam-Prep Apps
These apps focus on lessons, knowledge checks, pathology clips, or board preparation. They complement scanning practice but do not simulate a complete clinical examination.
4. Core Ultrasound Courses: Best for Structured POCUS Lessons and Q-Bank
Core Ultrasound Courses packages structured POCUS lessons and question-bank practice in an actively maintained mobile app. It is a good fit for learners who prefer an organized curriculum and knowledge checks instead of learning from disconnected videos or social posts. Major premium modules were listed at $99.99 when checked, so review the current in-app options before purchasing.
5. Prepry: Best for ARDMS and CCI Exam Prep
Prepry is the clearest exam-prep pick. Its current listing advertises more than 9,400 questions, 750 sonographic images, video courses, readiness scoring, spaced repetition, and mock exams across ARDMS, CCI, and ARRT pathways. It is designed for board preparation, not probe handling, so pair it with hands-on training or a simulator.
6. NYSORA Point of Care Ultrasound: Best Bedside Learning and Reference App
NYSORA’s POCUS app combines fundamentals, organ-based assessment, step-by-step procedures, algorithms, images, videos, and quick bedside references. The strength is breadth and fast clinical lookup rather than simulated scanning. It is a useful companion for learners who want a visual reference before or after supervised examinations.
7. The POCUS Atlas: Best Free Ultrasound Image Atlas
The POCUS Atlas is a free, open-access collection of ultrasound pathology clips and teaching cases. It is excellent for pattern recognition, unusual findings, and normal-versus-abnormal comparison. Android readers should use the mobile website because we could not verify a current Google Play listing. This is an image atlas, not a guided scanning course.
Ranks 8 to 10
Best Handheld Ultrasound Companion Apps (Hardware Required)
8. Butterfly iQ: Best Handheld-Probe App Ecosystem
Butterfly’s app controls the iQ family of handheld scanners and connects presets, AI-assisted guidance, documentation, image management, and education within one ecosystem. The software is polished, but it is not a standalone ultrasound app. It is useful only with compatible Butterfly hardware and the applicable plan.
9. Clarius Ultrasound: Best Controls for a Wireless Probe
The Clarius app controls the company’s wireless scanners, with presets, imaging adjustments, exam management, and AI-assisted tools designed for phone and tablet use. It is a strong fit for clinicians who want a cable-free probe and modern touch interface. The app has no practical scanning function without matching Clarius hardware.
10. Vscan Air: Best Companion App from a Legacy Ultrasound Brand
GE HealthCare’s Vscan Air app pairs with its wireless dual-headed probe and supports scanning, measurement, annotation, storage, and secure sharing. Its appeal is a compact probe backed by a long-established ultrasound manufacturer and a workflow familiar to clinicians using GE products. It is not an educational simulator.
Start without paying
Best Free Ultrasound Apps: The Short List
Start with the free guided case in POCUS Simulator for structured practice, The POCUS Atlas for pathology clips, and the free download of NYSORA for bedside reference, noting that full NYSORA access requires a subscription. PoCUS Pocket Trainer also offers a free iPhone download. A free companion app is not free hardware: Butterfly iQ, Clarius, and Vscan Air still require their manufacturers’ probes.
Common questions
Best Ultrasound Apps: Frequently Asked Questions
What is the best ultrasound app for beginners?
POCUS Simulator by Ultrasound Fanatic is our top pick for beginners who want guided cases, protocol steps, probe-position cues, image recognition, and feedback without needing a machine. We make the app and disclose that relationship. PoCUS Pocket Trainer is a strong iPhone-only choice for spatial anatomy, while NYSORA is better for reference reading.
Can a phone perform an ultrasound without a probe?
No. A phone alone cannot acquire diagnostic ultrasound images. Learning apps can simulate scanning or teach image interpretation. Butterfly iQ, Clarius, and Vscan Air use the phone as the display and controls, but each requires its manufacturer’s compatible ultrasound probe.
What is the best free POCUS app?
The best free choice depends on the task. The POCUS Atlas is excellent for pathology clips, PoCUS Pocket Trainer teaches probe-to-image relationships on iPhone, and POCUS Simulator includes a free guided case. NYSORA also has a free download, with a subscription required for full access.
What is the best ultrasound app for ARDMS or SPI exam prep?
Prepry is the strongest dedicated exam-prep option in this list. Its listing advertises more than 9,400 questions, 750 images, mock exams, readiness scoring, spaced repetition, video courses, and coverage across ARDMS, CCI, and ARRT exams. It should still be paired with hands-on scanning practice.
What is the best ultrasound app for Android?
POCUS Simulator is our Android pick for guided POCUS cases without a probe. Scanbooster is the better Android choice for broad virtual ultrasound volumes, Prepry is best for registry exam preparation, and NYSORA is best for bedside reference. The POCUS Atlas does not have a verified current Google Play listing, so Android users should open its mobile website.
Are ultrasound simulator apps a substitute for supervised scanning?
No. Simulator and education apps can build protocol knowledge, probe-to-image reasoning, image recognition, and confidence before a lab or clinical shift. They cannot validate clinical competence or replace supervised practice on real patients with an approved ultrasound system.
