User Reviews

Users generally value WikEM’s content—essential, centralized emergency medicine reference, useful on the job and for quick pharmacology lookups. However, sentiment is dominated by frustration with the move to the Eolas platform: a disruptive migration that many find non-user-friendly and that erases or complicates favorites and account linking. Additional widespread issues include login/account creation glitches, random crashes on iPhone, unreliable favorites, and broken search after updates. Content remains strong, but the new platform and stability issues undermine usability.

Pros

Essential, centralized emergency medicine reference content.
Great on-shift resource / handy in the field.
The standalone app back after the EOLAS transition is appreciated.
Pharmacology content is helpful for quick questions.

Cons

Migration to the Eolas platform resulted in a non-user-friendly experience with loss of features (e.g., favorites) and compatibility problems.
Login and account creation problems are widespread, including glitches, timeouts, and internal errors.
Crashes and random quitting on iPhone reduce reliability.
Favorites feature does not save or add properly (stars fail or load indefinitely).
Search functionality broken or unreliable after updates (incorrect results, missing options).

So glad the stand alone app is back.

I really loved the APP before they transitioned to EOLAS. They brought it back which is really good but the app is now glitchy and crashes on its own on IPHONE. Please fix the issues and I would be more than happy to buy it again. Has so much potential.

I’ve been recommended this app but the login account creation interface is glitching and fails to send login info to establish an account and login Updated 4/2/2026 it works now but does quit randomly very frequently, like 5 times per trying to read a diverticulitis article
