Review momentum
20/100
faster than 0% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

“THE ORIGINAL AND STILL THE BEST” —EMS Magazine
Twenty-three years after publication, the EMS Field Guide remains the most widely-used reference in EMS history. Carried in the pockets, phones and emergency vehicles of millions of first responders, this is the guide EMS Magazine calls “the original and still the best.”
The EMS Field Guide app puts critical information at your fingertips with rich content, detailed illustrations and pioneering features. This app is available in two editions— Advanced Life Support (ALS) and Basic & Intermediate Life Support (BLS)—designed specifically to correspond with each tier of EMT certification and practice, so you know you have the right tool for your job.
The Advanced Life Support (ALS) app equips the Paramedic or EMT-P to triage and address trauma. It provides fast, easy access to vital assessment information, medications, and drug doses; quick interpretation of 12-Lead EKGs; and the latest CPR and ACLS algorithms from the American Heart Association (AHA). The ALS app is also suitable for Intermediates whose practice orders require a more detailed understanding of these topics.
