9 questions to ask before you choose a skincare tracker app

At a glance: the 9 questions and WisoCare's answers

The table lists the nine questions, why each one matters and WisoCare's short answer; the sections below go into detail.

Privacy: five questions about your photo and your data

If you want a private skin analysis app, these five questions matter most; check each answer against the app's privacy policy.

1. Is my photo uploaded to a server?

Some apps send your photo to a server for analysis; if so, ask where it's stored and when it's deleted.

WisoCare: No. Photos are written only to the app's own temporary folder and deleted once measured. If you stop partway through the three angles, the frames are kept for at most 30 minutes so you can resume, then deleted. So there's no before-and-after gallery either: your history keeps results (numbers and levels), not photos.

2. Where is the photo processed, and what leaves my phone?

“We don't upload your photo” doesn't mean nothing leaves your phone; ask what the AI receives.

WisoCare: Your phone does the measuring: it finds 468 points on your face and turns the color of 5 zones into numbers. Photos, face points and the skin mask are never sent. With the separate AI permission, your skin metrics and the information you choose to share in the app (never images) go to the AI. That's why we don't say “fully anonymous”: your photo stays on your phone, but the health details you allow are sent too, to personalize your guidance. Without the permission there's no analysis, but routine tracking still works. The full list, and who receives what, is in the Privacy Policy.

3. Do I have to create an account?

An account links your data to your name or email on a server.

WisoCare: No. An account (Apple, Google or email) only adds cloud backup: your profile, history and routines, encrypted server-side in Europe and restored on your next phone. Turning backup off deletes the cloud copy.

4. Can I delete my data?

Check whether deleting takes a button in the app or a written request.

WisoCare: Yes, in the app. “Delete Account” in Settings deletes your account, your cloud backup and the data on your phone; without an account, “Delete all data” in Profile clears the data on your phone. You can use your rights under KVKK and GDPR (access, deletion, objection) by writing to info@wisocare.com.

5. Does it show ads or ask to track me?

Free apps often earn money through ads; ask how often they appear and who decides about your advertising ID.

WisoCare: On the free plan, at most one full-screen ad a day may appear, after an analysis; Premium has none. Apple's App Tracking Transparency prompt lets you decide whether ads may use your advertising ID. Even without that permission, the names of some app events (such as “skin analysis completed”) go to Meta for ad measurement; your photos and skin data don't. We don't sell your data; the Privacy Policy names the ad and ad-measurement services and what each one receives.

Claims: what does the app promise, and how does it show results?

A skincare app can describe your skin; it shouldn't claim more. These two questions check that.

6. Does it claim to diagnose or name skin conditions?

Naming a condition or suggesting treatment is a medical assessment; if an app does either, ask what backs the claim.

WisoCare: No. It describes what it measured, zone by zone, in plain words: redness, shine, pigmentation and a visual moisture estimate. Shine is light reflecting off the skin's surface; besides oil, moisturizer, sunscreen, sweat and the angle of the light cause it too, so it's a surface observation, not an oiliness diagnosis. Tap “I do not see this on my skin” to remove a finding you don't see. The app's own note: “These measurements are for trend tracking, not a clinical assessment.”

7. Does it give you a single number, or compare you with your own starting point?

Light, angle and time of day change how the same skin looks in a photo; ask what the result is measured against.

WisoCare: Not a single number. You get a level word (such as Very Good, Medium or Prominent) for redness, shine, pigmentation and the visual moisture estimate, plus a short note for each zone. Three frames per angle are averaged, the whites of your eyes are the white reference, and thresholds adapt to the Fitzpatrick skin type you pick. Shine is decided on your phone; the AI picks the other levels by fixed number rules we wrote and explains the measured numbers without inventing them. A one-time calibration photo sets your starting point; after about three analyses, your own history joins in. Product scans follow the same line: no scores, no “good or bad” verdicts.

Everyday use: does it fit your day and your phone?

These two questions check whether an app fits your day, your device and your connection.

8. Can I just track my routine without an analysis?

Habits grow from small daily steps; a required analysis may be more than you need.

WisoCare: Yes. When you start, pick “I just want to track my routine”: no analysis or AI permission needed. Your products are placed on your calendar; you tick off morning and evening steps for today or up to two days back, and every day with at least one step extends your streak. There's no notebook or skin journal; tracking runs on the steps you tick off. The routine, calendar and reminders are free. Details: Skincare tracker.

9. Which languages and devices, and how much works offline?

The app should run on your phone, speak your language and still help when you're offline.

WisoCare: Turkish and English, switchable in Settings; iPhone only for now (iOS 15.1 or later). Measuring happens on the phone, but an analysis needs a connection because the AI writes your guidance. The routine, calendar, reminders and product scanning work offline: 17,868 product barcodes ship with the app, your phone reads labels and the assessment is rule-based. Web search for products and the AI check for ingredient pairs outside our rule table (both Premium) need a connection. Details: Product scanner.

Which skincare tracker app should you use?

The one whose answers you're comfortable with. Instead of taking one recommendation on trust, look for the answers to these nine questions on each app's App Store page, in its App Privacy section and in its privacy policy.

WisoCare is free to start: your first analysis happens right away, then one every 45 days, and the routine, calendar, reminders and three catalog scans a week are free too. Premium removes the analysis wait, the scan limit and ads; eligible users get a 3-day free trial. See the current price on the App Store.
