### 2/5 — 2 stars

*2026-03-25, version 7.45*

App is informative and has great information. Downside is it is usually slow to respond or unresponsive.

### 5/5 — Best Derm App

*2026-03-22, version 7.45*

Hands down, this app has the best clinical image library for reassuring my patients. Definitely recommend using. Totally worth the subscription

### 1/5 — Lie on ads

*2025-06-19, version 7.45*

Terrible

### 1/5 — VisualDx

*2024-08-29, version 7.41*

Before this App was free. We wish to make free again

### 1/5 — Poor customer service

*2024-05-24, version 7.40*

Paid for derm expert unable to access service. Sent email and called customer service without resolution

### 1/5 — Buyer beware

*2024-01-26, version 7.37*

They make it unnecessarily hard to cancel the subscription (have to go to the website rather than just allowing you to manage the account from the app) and then charge you for renewal anyway. App itself works fine.

### 5/5 — Excellent app,  A few laggy options

*2023-06-23*

Excellent app for most use case scenarios especially looking at pictures and synopsis.

Other options are less optimized for phone use.

Such as the quiz option. Frequently crashes or is unable to load.

Otherwise it is an app that I use on an almost daily basis in a very educational and self improving manner.

Many in my hospital have also started to use. Especially with a mobile app and fast access on the go.

Please continue to support medical education with great seminars and opportunities for both residents and medical students.

All the best in the future and hopefully more to come.

### 5/5 — The best app for providers

*2023-05-09, version 7.31.3*

This is the most helpful app ever for providers. Saves a ton of time and helps diagnose more accurately.

### 1/5 — Won’t allow me to cancel my subscription!!!

*2023-02-04, version 7.30.2*

Registered on the webpage and gave it a try, overall good impressions, but just wasn’t for me. Now when I try to cancel my subscription (free trial but will start payment next month) it won’t let me do it. Deleting the account isn’t an option since the payment will go on I think

### 2/5 — Not worth the cost

*2022-10-12, version 7.29*

It’s fine but the price is crazy high.

### 8.11.0 — 2026-07-09

We've made it faster to build and refine a differential - even when the patient findings are hard to pin down.

•  Guided Workups: Not sure how to describe a lesion? Step-by-step prompts for skin, oral, eye, nail, and hair/scalp.
•  More refined "Consider First": Differential results are shorter, giving you a more targeted starting point for any patient case.
•  CompareView on mobile: Compare individual diagnoses side by side, pulled straight from diagnosis text or a custom differential.
•  Dynamic Differential: Remove diagnoses you've ruled out, or add ones to a working set to view in CompareView.
•  Mobile single sign-on: Just enter your email and sign in with your institution's credentials (requires institution setup).

As always, this release includes performance improvements and bug fixes. Questions or feedback? We'd love to hear from you.
