Heart Murmurs Pro is a cardiac auscultation trainer for medical and nursing students, residents, and anyone studying how to tell heart sounds apart by ear. Listen to 24 heart sounds and murmurs. For each one, see a labelled waveform showing exactly where the sound falls in the cardiac cycle, a diagram of the auscultation site it belongs to, and the study notes that go with it — then test yourself. This is a study aid, not a clinical tool. Nothing in it is meant to guide decisions about a real patient's care. FREE TO TRY Five sounds are free — normal, aortic stenosis, mitral regurgitation, mitral stenosis and the S3 gallop — each with its waveform, its auscultation site and its study notes, and you can quiz yourself on them. One purchase unlocks the other 19 sounds and the study tools described below. No subscription. WHAT'S INSIDE • 24 heart sounds and murmurs — from normal S1/S2 to aortic stenosis, mitral regurgitation, hypertrophic obstructive cardiomyopathy, pericardial friction rub and summation gallop • A labelled waveform for every sound, with systole and diastole marked and S1, S2, A2, P2, ejection clicks, opening snaps and gallops called out where they actually occur • Half-speed playback, for murmurs that go by too fast at full speed • Compare any two sounds — a murmur against normal, or against the one you keep mistaking it for — and switch between them with one tap • Auscultation site diagrams showing where each sound is heard best • Seven sections of study notes per sound: description, etiology, pathophysiology, physical examination, diagnostic evaluation, clinical presentation and treatment • Room for your own notes on any sound QUIZ YOURSELF Choose which murmurs you want in the pool — everything, one of the built-in sets, your favorites, or a handful you pick — then choose how many questions and start. Five for a quick drill, twenty when you have time. Answer from six options, or name it yourself and score your own recall. Switch on re-asking and a murmur you miss comes back a few questions later, because that is the one you needed to hear again. At the end you get your score and, more usefully, the list of what you missed — with a button to practice exactly those. Every murmur keeps its own record, so the app can show you where you are weak and build a session out of it. BUILT FOR STUDYING • Works completely offline — no account, no sign-in, nothing to set up • Free to download; one purchase unlocks everything, with no subscription and no ads • English, Spanish and Simplified Chinese • Full split-view layout on iPad • Dark Mode • Favorites and search across the whole library • A cardiac exam guide covering auscultation technique, the five listening areas, and the eight characteristics used to describe a murmur Headphones are strongly recommended. Phone speakers roll off the low frequencies that carry S3, S4 and mitral stenosis. Heart Murmurs Pro is an educational tool for learning cardiac auscultation. It is not a diagnostic device and must not be used to diagnose or treat anyone, or to guide decisions about a patient's care. Always defer to your training, your supervisors, and your institution's protocols.

PLEASE BE ADVISED THAT THIS IS A LEGACY VERSION OF THE NIH TOOLBOX SYSTEM AND WILL BE RETIRED IN JUNE 2028. New users are strongly encouraged to download the NIH Toolbox V3 app instead of this legacy version: https://apps.apple.com/us/app/nih-toolbox-v3-en-espa%C3%B1ol/id6476326376. Users whose studies end after June 2028 must plan to transition to the NIH Toolbox V3 app before then. The annual subscription cost of this app will increase each year through its retirement. *** Important Hardware Note: iPads (2018 and newer models) with 9.7- to 11-inch screens are recommended. Data collected on iPads with 12.9" screens has not yet been validated. *** NIH Toolbox is a multidimensional set of performance and person-report measures that assess cognitive, sensory, motor, and emotional function in people ages 3-85, designed for research and clinical use (see www.NIHToolbox.org). NIH Toolbox was developed by more than 250 scientists over 6 years and sponsored by the 15 institutes of the National Institutes for Health that make up the NIH Neuroscience Blueprint. NIH Toolbox includes over 200 measures, for stand-alone use or as part of a complete assessment battery. With the advent of the NIH Toolbox, researchers can now assess function using a common metric and can “crosswalk” among measures, essential to the process of pooling data and often necessary when a large and diverse sample is needed. This version contains the Spanish-only version of the measures. With the purchase of this app, you will also have access to the PROMIS® measurement system funded by the National Institutes of Health. NIH Toolbox does not require a subscription for many features; however, a subscription is required to record assessment responses and to view and export results. Subscriptions are offered for purchase within the app for use on up to 10 iPads. Purchased subscriptions will automatically renew unless auto-renew is turned off at least 24 hours before the end of the current subscription period. Cancellation of the current (paid) subscription is subject to Apple’s discretion. Users can enjoy a free trial period to explore the NIH Toolbox app, but data will not be saved and results will not be generated during the free trial. The free trial period will be forfeited when the user purchases a subscription. Manage your subscription by going to your Apple Account Settings after purchase. All content needed to administer NIH Toolbox tests is available in the app, though some tests require additional hardware or materials. Please create a free account at www.NIHToolbox.org to access the Administration and Technical Manuals, supplemental materials, and list of publications. With the purchase of this app, you will immediately have access to tests in the Emotion, Motor, and Sensation domains. Tests in the Cognition domain require the successful completion of a separate approval on www.NIHToolbox.org. This approval process is included in the cost of the subscription; no additional purchase is necessary. Generally, approval will be granted to researchers and clinicians with the knowledge and training to use neuropsychological tests. Contact help@nihtoolbox.org for more details. Important information about the intended use and data security: * NIH Toolbox is not intended for use outside of research or clinical application. * Users control how data is managed. Data export via iCloud, email, and File Sharing can be enabled/disabled in the app. * Data exports (.csv format) and assessment reports (.PDF format) may be emailed from NIH Toolbox.
