This is a non-comprehensive list of popular and recommended iPhone apps for the medical field. This
is by no means an exhaustive list, as new apps are being developed every day. In most cases, several
options have been given for each category. Apps tend to cover the same general things with each app
giving a unique tool. In those cases, you might need two have two similar apps available for different
settings or to have everything you need.
Drug Reference – You will want a reference that will allow you to check for side-effects, cross-
reference interactions, correct dosings, and safety information on the fly. A must-have for any
budding clinician.
ePocrates (Free/Premium) – The current standard of drug references. The Premium edition gives
you access to OTC medications, and an information database with common diagnoses and labs. It also
has Pill ID, Interactions, and a small list of equations.
LexiComp (Subscription) – A more substantial version of ePocrates with a larger database and
more tools. Free subscription can be obtained through the AMEDD virtual library for those with an
AKO/DKO account. Slightly harder to navigate through than ePocrates.
MicroMedex (Free) – A more substantial version of ePocrates with slightly more detail than
LexiComp, but focusing almost exclusively on medications.
2011 EMRA Antibiotic Guide ($15.99) – Antibiotic guidelines, with a built in dosage calculator.
You can search by diagnosis, organ system, or organism. Very clear guidelines, very easy and quick to
use. Unlike the others, it helps in selecting the appropriate medication rather than as a full drug
reference.
Calculators – Clinical equations, both for lab values and clinical guidance calculators. Often, one
program will have equations that others don’t.
Mediquations ($4.99) – A lot of calculators, conveniently sorted by category.
MediMath ($4.99) – A lot of calculators, conveniently sorted by category.
Neuromind (Free) – Criteria, rules, and guidelines specific to neurology and neurosurgery.
Clinical – Tools to be used in the every-day clinical setting, whether inpatient or outpatient.
PerfectOBWheel ($1.99) – Allows you to check estimated fetal size, due date, conception
date, LMP, and conception date by LMP, conception date, due date, or gestational age. Other apps
usually restrict you to either inputting gestational age or LMP.
MD On Call ($3.99) – Guidelines for diagnosing and treating many emergencies or conditions
you will encounter on call, ranging from abnormal lab values, procedures, abnormal ECG’s, and patient
conditions.
Diagnosaurus DDx ($0.99) – An excellent resource for those just starting on their clinical
rotations. Selecting a particular organ system or diagnosis, it will give you a large differential diagnosis
and other differentials. There is no information on likelihood or required tests, but a great tool for
broadening your differential or remembering all your zebras or horses.
Pedi Stat ($2.99) – Entering age, weight, or height will give many guidelines, formulas, vital
signs, and appropriate dosings.
PediSafe ($0.99) – Selecting patient weight will give you vital signs, equipment size, and
standard doses for many emergency medications.
10 Sec EM ($1.99) – Many clinical guidelines and rules used in the ER, such as the Ottawa
Ankle Rules, Stroke scores, pneumonia rules, SIRS rules, and many others.
WellAdult ($2.99) – More intuitively organized than the free ePSS app, the recommendations
are pre-organized by age. It gives screening tests, immunization and preventive guidelines, cancer-
screening, information for special populations, and even non-recommended screenings in case the
patient inquires.
WellCheck ($2.99) – Designed for pediatric well-checks age 1 week to 5 years. Separated by
age group, it will give you milestones, growth parameters, immunization schedules, and anticipatory
guidance for that checkup.
AHRQ ePSS (Free) – Preventive medicine straight from the US Publlic Services Task Force. The
search option allows you to narrow down the counseling/tests required, and the tools offer a lot of
questionnaires. However, it is difficult to navigate through, especially in a hurry.
ACLS Advisor ($8.99) – Examples of various pathologic ECG’s and the guidelines for them.
Normal Lab Values ($1.99) – Ranges of normal values for a lot of standard and specialty-
specific lab tests.
National Center for Telehealth and Technology (Free). Mobile apps for TBI and PTSD

Reference – many of these references are things that are available on the internet or in reference
books for free. Their appeal is in having the ability to look them up quickly when you don’t have a
book (clinic/bedside) or are in an internet dead-zone (inside of a hospital).
Core Ortho ($39.99) – An excellent resource for the musculoskeletal exam. It gives many
specialty tests for the physical exam with descriptions, sensitivity and specificity, and video
demonstrations if you have internet access.
PubSearch (Free) – Allows you to search PubMed for articles and papers on virtually any
topic. Will return a reference, and often the abstract as well. The PubSearch Plus app gives you
unlimited results and access to full-texts, but isn’t something you need on an iPhone. You’re often better
waiting to download the full PDF once you have a title.
Modality (Free) – The main application is free. This app serves as a store within the iPhone,
allowing you to purchase other resources, such as Netter’s, full reference books, and other tools.
SkyScape (Free) – The main application is free. This app serves as a store within the iPhone,
allowing you to purchase other resources, such as Netter’s, full reference books, and other tools.
GoodReader ($4.99) – Not specifically a medical app. This allows you to add images,
documents, PDF’s, and other files to your iPhone and view them. An excellent resource for putting in
your own documents (MMSE, CHF/asthma guidelines, etc.). Has a method to organize files by folders as
well, something lacking in many other apps.
Pocket Derm ($0.99) – Provides images and descriptions of many dermatologic conditions.
Merck Manual ($34.99) – Also available through Skyscape and possibly Modality, the stand-
alone version is a lot less likely to crash while you’re searching for something. A large general medical
reference. It also allows you to mark favorites and have an outline of the article you’re reading.
Medscape (Free) – A reference source from webMD. Lots of information, tailored to both the
clinician and the patient.
SonoAccess (Free) – Images, cases, and how-to videos of ultrasound techniques. The focus
is on the videos, but requires internet access.
Ultrasound EM ($4.99) – Example images and instructions for performing many of
ultrasound tests such as the eFAST, AAA screening, and others. Does not require internet access.
Traumapedia ($9.99) – Treatment guidelines, information, and example x-rays for specific
fractures and dislocations. Very easy to navigate through.
Urgent Care ($8.99) – Guidelines and information for many patient complaints and
conditions. Unfortunately, it is organized into a single large page with a few links back to the top and
each section, making it difficult to find information quickly.
Eponyms (Free) – Specific to medical eponyms for diseases, syndromes, and a few tests.
Organized alphabetically without a search function or separation into categories makes it difficult to find
exactly what you’re looking for. Because it’s much less complete than med abbrevs, it’s often easier to
find it if you’re looking for only an eponym.
Med Abbrevs ($0.99) – A list of medical abbreviations, eponyms, tests, latin terms, and
common usage abbreviations. It is in alphabetical list format and very large, often making it difficult to
find what you need, especially if you’re unclear about spelling. You can tag specific abbreviations as
favorites.
Study Materials – similar to reference materials, but focused on reviewing material or as quick
questions.
Netter’s ($39.99) – Available in a stand-alone version, or often through another app, it allows
you to test your anatomy. It also allows you to pull up and show a particular anatomy slide to a patient.
This will often help with discussing their diagnosis or procedure. Anatomy, histology, and other subjects
are available.
Radiology 2.0/One Night in the ED (Free) – Example CT scans of common diagnosis. You can
test yourself with an unknown CT, or review one for a known diagnosis. Unlike many other apps, this
one allows you to scan through a small series of CT images, allowing you to search for pathology, rather
than giving you a single ‘perfect’ CT image of the diagnosis.
iCBCT Anatomy ($4.99) – Example anatomic CT images and a quiz specific to head CTs. The
example CT images are labeled.
Chest Xray Interpreter ($2.99) – Quick examples, and saved reports of CXR pathology. Also
gives you 20-questions style guide to analyzing any given CXR.
InstantECG ($0.99) – ECG basics (waveforms, axis, intervals) and examples of pathologic
ECG’s.
ECG Guide ($0.99) – Similar to the above, with fewer basic information, but also contains a
step-by-step walkthrough on interpreting an ECG.
