Getting started
Download and install
Get GP DermWizard from the App Store or Google Play. No email account is required — install and go.
First launch
After the splash screen you will see a one-time clinical disclaimer covering:
- Not a diagnostic device — decision support only
- Clinician responsibility for judgment and referrals
- Data privacy (no patient identifiers in AI modes)
- When to use urgent / 2WW pathways
Tap Continue to Homepage to enter the app.
Main navigation
Six bottom tabs: Home (diagnostic modes), Terminology, Atlas, Quizzes, History, and Settings.
Replay guided tutorials anytime via Settings → Replay Tutorials — covers body map, symptom picker, results, and each diagnostic mode.
Diagnostic modes
From Home, start a new consultation by choosing one of three modes. The home screen shows whether you are Online or Offline and how many cases you have saved.
AI-Assisted Modes (internet required)
- AI Differential — Build top differentials from location, morphology, distribution, and other terminology. Best for complex cases when connected.
- Visual Scan — Combined image analysis with optional clinical input. Opens the photo upload flow directly (not the four-step body-map wizard).
Offline Diagnostics
- Offline Scoring — Rule-based scoring from precise terminology. Works fully offline and privately — ideal for routine checks in poor signal.
Quick links on Home jump to Atlas, Terminology, and History. Recent cases appear under RECENT CASES.
Clinical decision support only — not a substitute for professional judgment. Always apply your own clinical assessment and local referral pathways.
Offline Scoring
Four-step wizard
The consultation flow shows a step indicator: Location → Age → Symptoms → Results.
Step 1 — Body map
Tap the affected area on the interactive body diagram. Optionally refine with sub-location chips (scalp, fingernail, etc.). The diagram can be turned to view different angles.
Step 2 — Patient details
Optional Age and Gender (Male, Female, Other, or Not specified). Skip if not relevant.
Step 3 — Symptom tags
Use the category sidebar (Morphology, Colour, Distribution, Nail Features, etc.) or Search across all features… Long-press any chip to see a reference image. Tap chips to select; use BACK, NEXT, or FINISH when ready. FINISH EARLY appears when confidence is very high.
Step 4 — Results
View ranked conditions with Matching features. Expand any card for details. Actions: DETAILS, PCDS GUIDANCE, VIEW ATLAS. Vote helpful/not helpful or Report missing diagnosis.
AI Differential
Same wizard, AI-ranked results
Follow the same Location → Age → Symptoms flow as Offline Scoring. On first use you will see an AI Data Processing Consent dialog — only anonymous symptom tags are sent; no patient identifiers.
Dual results tabs
On the results screen, switch between:
- Online — AI-ranked differentials with confidence scores, original vs AI score, and a written Rationale
- Offline — rule-based backup using the same tag-matching engine as Offline Scoring
Each result supports DETAILS, PCDS GUIDANCE, VIEW ATLAS, feedback voting, and Report missing diagnosis. Tap New Consultation to start again.
If connection drops during ranking, you will see a retry prompt — the offline tab remains available.
Visual Scan
Image Analysis workflow
From Home, tap Visual Scan to open Image Analysis. Steps: Upload → Context → Analyze.
Upload clinical image
Capture a new photo or choose from your library. Free tier: one image per scan. Pro: up to three angles per scan for better coverage.
Patient context (optional)
Add gender, quick-select symptom tags, and (Pro) Additional clinical notes to improve accuracy. Tap Start AI Analysis.
Clinical Analysis Report
The structured report includes:
- Primary morphology
- ABCDE clinical assessment (Asymmetry, Border, Colour, Diameter, Evolution)
- Differential diagnosis
- Clinical red flags
- Next steps
- View matching atlas images
Then New Scan or Finish. Images are processed securely and not stored unless you save them.
Terminology & Atlas
Terminology tab
Browse dermatology terms by category — General, Morphology, Patterns & Distribution, Nail signs, Special Signs, and more. Use Search all guide… to find any term mid-consultation. Tap images to zoom. Long-press symptom chips in the wizard to see the same reference images.
