The DermLite App is a free download from the Apple App Store. Search for "DermLite" on your iPhone, or use FotoFinder's direct link: DermLite on the App Store.

There is no charge for the app itself. Some cloud features (image syncing and backup through FotoFinder Hub) use a separate Hub account, which has both free and paid plans — more on that in the questions below.

Right now the DermLite App is iPhone only — it was designed to provide the best experience on Apple devices first. FotoFinder has stated that an Android version is in the works, but no release date has been announced. If you use Android, keep an eye on FotoFinder's announcements (or check back here — we'll update this page when it ships).

The short version: a reasonably current iPhone running a recent version of iOS, plus a DermLite DL5 Plus dermatoscope. The complete, always-current requirements are published in the official user manuals:

• DL5 Plus user manual (PDF)
• FotoFinder Hub documentation (for the optional cloud features)

Using the DL5 Plus with the app, the maximum zoom level exposed by the software is approximately 20× (FotoFinder's own definition of the "~20×" level). Keep in mind that with digital dermoscopy, the effective on-screen magnification also depends on your phone's screen size and how far you pinch-zoom into a captured image afterward.

The app's interface is available in many languages (English, Spanish, French, German, Italian, Portuguese, Japanese, Chinese, and numerous others), and the user manual is also published in multiple languages.

To change the language:

1. Open the app's menu and go to Settings.
2. Open the System section.
3. Tap Language & Region.
4. Pick your preferred working language from the list. The change applies immediately.

Partially. The app does not currently offer dedicated trichoscopic image analysis (no automated hair-density counts or similar). However, you can absolutely still use the DL5 Plus and the app to capture, store, and monitor scalp and hair images over time — the standard capture and follow-up comparison tools work on any skin surface, including the scalp.

Yes — FotoFinder intends the DermLite App to replace the handyscope Pro app later in 2026.

The good news for existing handyscope users: Hub accounts are not tied to a specific device or app. Your existing Hub account, and the images in it, work with the DermLite App exactly as they did with handyscope. Just sign in with your same FotoFinder ID.

No. FotoFinder Hub and FotoFinder Universe are two separate platforms, and the DermLite App connects only to the Hub cloud solution. If your practice runs Universe (as some Wireless-app users do), images from the DermLite App won't flow into it.

You can pair as many DermLite scopes as you wish to the same account, on any plan — including the free one. Multiple scopes alone do not require Premium.

Where Premium comes in: it allows simultaneous access from multiple apps/devices — for example, a skeen unit and the DermLite App signed in and working at the same time, or two active users. On non-Premium plans you get one active user/device at a time (additional users/devices can also be added to any plan for an extra charge).

Calibration is handled for you: the app uses internal procedures to calibrate the zoom level automatically — there's nothing to set up manually.

White balance calibration (making colors accurate) requires a lens with the BL connection; the app walks you through it under Settings → System → Camera → White Balance Calibration. FotoFinder deliberately keeps manual light calibration out of users' hands because it's very easy to get wrong — the automated routine is more reliable.

Images are always stored locally inside the app's own storage on your phone. If you've connected a Hub account and enabled synchronization, they are also synced to the Hub cloud (within your plan's storage allowance) — giving you a backup and access from a browser.

Direct save to the iPhone camera roll is not available yet, but FotoFinder has said upcoming versions will add the standard iOS Share function — letting you send images to Photos or any other app, just like the Share button in handyscope Pro.

Yes. The free subscription tier includes full access to the patient information management features — you can create patients, assign images to them, and organize exams without paying anything. Paid Hub plans mainly add cloud storage capacity and multi-user/multi-device features.

Step by step:

1. Attach the scope to your iPhone using the magnetic clamp (see the MCC question in section 2), so the DL5 Plus lens sits over the phone's rear camera.
2. Open the DermLite App. Go to the Dermatoscopes screen and tap Choose your Device.
3. Select DermLite DL5+ from the list of detected devices.
4. That's it — the app confirms the connection by showing the My DermLite DL5+ status page, with live readings for battery level, charge state, magnification stage, polarization mode, and more.

Once connected, the app communicates with the scope wirelessly — it can switch light modes and read the device status without any cable.

The DL5 Plus offers cross-polarized, non-polarized, parallel-polarized, and UV lighting, plus PigmentBoost® enhancement — and you can switch between them two ways:

Option A — buttons on the scope itself:

• One button toggles polarized / non-polarized light. Polarized light cuts surface glare so you see structures beneath the surface; non-polarized shows surface texture, scale, and shine.
• A second button toggles UV light for fluorescence and pigment work.
• A third button activates PigmentBoost®, which boosts contrast to bring out pigmented structures. It can be combined with the other modes.

Option B — from inside the app:

• In the live capture view, tap the light control and use the brightness slider at the bottom of the screen to fine-tune intensity for the current mode.
• Because the app talks to the scope wirelessly, mode changes show up instantly in your live view — the video demonstrates this with a side-by-side comparison of polarized vs. non-polarized on the same lesion.

You have two ways to sign in. Both start the same way: install the app and open it.

Option A — email and password:

1. On the Sign in with your FotoFinder ID screen, enter the email address and password of your FotoFinder account.
2. The app signs you in, then asks you to set a 4-digit PIN to secure the device. Enter and confirm your PIN.
3. Done — the app confirms your device is registered and secured.

Option B — QR code (handy if you're already signed in to Hub on a computer):

1. On your computer, sign in to FotoFinder Hub and go to Settings → My Devices.
2. Click + Add new device. A QR code appears (it expires after 3 minutes; the page refreshes it automatically).
3. In the app, choose Sign in with QR code and point your phone's camera at the code on your computer screen.
4. You'll see "Sign in successful" and your new device appears in the Hub device list.

Just like with the DL5, the DL5 Plus attaches to your phone with a physical adapter — either the Magnetic Connection Clamp (MCC), which is included, or an iPhone-specific DL Connection Kit case.

Step by step (MCC):

1. Find your iPhone's rear camera cluster — the clamp needs to align the scope's optics with the phone's main camera.
2. Attach the magnetic ring/clamp to the back of the phone, centered around the camera area, and press it on firmly.
3. Bring the DL5 Plus's magnetic mount up to the ring — it snaps into place magnetically.
4. Give it a gentle wiggle to confirm it's seated: the magnetic connection is strong enough to hold the phone's full weight.

Remember the connection between app and scope is wireless — the clamp is purely mechanical alignment. You can detach and re-attach the scope in seconds between patients.

To reset the DL5 Plus to factory defaults and clear all paired devices from its memory, press this button sequence while the device is switched off:

UV → PB → PB → UV → PB → PB → UV

(That's the UV light button and the PigmentBoost (PB) button, pressed in that exact order — seven presses total.)

The BLE indicator light will flash to confirm the reset was accepted. After a reset you'll need to reconnect the scope in the app (see "How do I connect my DermLite to the app?" above).

Official FotoFinder tutorial (no narration — written steps below).

1. From the main screen, tap the settings (gear) icon.
2. Choose My Devices. Every scope paired with the app is listed here.
3. Tap a device (e.g., DermLite DL5+) to open its detail page.

The detail page is surprisingly informative — it shows the scope's serial number, model number, total runtime, charge count, battery percentage and voltage, plus usage statistics such as total sessions, patients, and images taken with that scope. This is also the screen to check when contacting support about a hardware question, since your serial number is right at the top.

Official FotoFinder tutorial (no narration — written steps below).

1. Open Settings from the main menu.
2. Go to the AI Score section.
3. Choose Online or Offline.

What's the difference? In online mode, AI scoring runs through FotoFinder's cloud (requires an internet connection). In offline mode the analysis runs on the phone itself, so it works with no connection — useful in exam rooms with poor reception or when you prefer images not leave the device for analysis.

Official FotoFinder tutorial (no narration — written steps below).

1. Open Settings.
2. Tap Tutorials.
3. Pick a tutorial from the list — for example the Image Screen Tutorial or Gallery Tutorial — and the app walks you through that screen's features interactively, right on top of the real interface.

These built-in walkthroughs are the fastest way to learn a screen you haven't used before, and you can repeat them any time.

Official FotoFinder tutorial (no narration — written steps below).

1. Open Settings.
2. Tap Synchronization (first item in the list).
3. Switch the sync toggle on (it turns green).

From then on, patients and images captured in the app are synchronized to your FotoFinder Hub account automatically, within your plan's cloud storage allowance. You can then view the same records from any browser by signing in at Hub. If you'd rather keep everything local-only, simply leave the toggle off — images always remain stored on the phone either way.

Official FotoFinder tutorial (no narration — written steps below).

1. Open Settings.
2. Go to System.
3. Tap Color Theme and select the theme you prefer from the list.

The change applies immediately — pick whichever scheme is most comfortable for your eyes and exam-room lighting.

You're prompted to create a PIN when you first register, but you can manage it any time:

1. Open Settings and go to Security.
2. Tap Create PIN and enter a 4-digit code on the keypad (or use Change PIN if one already exists).
3. To turn the requirement off, use the Disable PIN toggle on the same screen.

Official FotoFinder tutorial (no narration — written steps below).

1. Open Settings.
2. Go to System.
3. Tap Camera.

Here you'll find the capture-related options, including White Balance Calibration — a guided routine that makes sure the colors in your images are true to life (important when you're judging subtle shades of brown, red, and blue-grey). White balance calibration requires a lens with the BL connection; the app provides on-screen instructions when you open it.

Official FotoFinder tutorial (no narration — written steps below).

1. Open Settings and go to System.
2. Tap Diagnostics.
3. Select AI Diagnostics.

A green checkmark next to the AI entries (e.g., AI 3D Skin Configuration) confirms the AI components are installed and working on your device. If something shows as not active here, this screen is the first thing FotoFinder support will ask about — the same menu also offers Device Diagnostics and Export Diagnostics for troubleshooting.

The idea: you spot a lesion of interest during the exam, so you capture the magnified (dermoscopic) image immediately — then attach the context afterward.

Step by step:

1. With the scope on the phone, place it on the lesion and capture the dermoscopic image from the live view.
2. If enabled, run the AI score — the app shows a color-coded risk result for the captured image.
3. Tap Assign to patient and pick the patient (or create a new one on the spot).
4. Add the clinical context: take an overview photo of the body region, and mark the lesion's location — the app places a marker on the overview image and on a 3D body model, so anyone reviewing later knows exactly where on the body the close-up came from.

Result: one record containing the dermoscopic image, its body location, the overview photo, and (optionally) an AI score — all linked to the patient.

Official FotoFinder tutorial (no narration — written steps below).

The idea: the reverse order — start with the big picture, then zoom in. This suits systematic full-region checks (for example, documenting a patient's back).

Step by step:

1. Take a clinical overview photo of the body region with the phone's normal camera view (scope not on the skin yet).
2. Mark each lesion of interest on the overview photo — the app places a red marker at each spot, and you can refine the location on the 3D body model (Choose localisation).
3. Now go marker by marker: place the scope on the corresponding spot and capture the dermoscopic image for each marked lesion.
4. Each close-up is automatically linked to its marker, so the overview photo becomes a clickable map of the exam.

Result: the same complete record as Workflow 1 — overview, precise locations, and a magnified image per lesion — but built top-down instead of bottom-up.

Official FotoFinder tutorial (no narration — written steps below).

The idea: monitoring is where digital dermoscopy really pays off — the app puts the old and new images of the same lesion side by side so change is easy to see.

Step by step:

1. Open My Patients and select the patient.
2. Open their gallery and tap the lesion you want to recheck — its previous image(s) open.
3. Choose the follow-up/capture option and take a new dermoscopic image of the same lesion.
4. The app shows the previous and current images side by side for direct comparison, and saves the new image into the same lesion's history.

Over time each lesion builds a dated image series — exactly what you want for documenting stability or catching change early.
