Best Acne Tracker App: 7 Apps to See What's Actually Working

The best acne tracker app is the one that ties dated photos to the things that might drive your breakouts, then shows the trend over weeks. Pori scores a selfie and lines it up with a sleep, water, stress and diet diary. Skinsign and Trace lean hardest into trigger patterns, Puffin maps breakouts by face zone, and Clear is a private photo log with a community attached.

We make Pori, so we've put it first; here's what each app does well. Below you'll find a comparison table, a short profile of each app built from its US App Store listing as of October 2026, and a plan for logging acne so the data actually answers a question. For the method itself, see our guide to tracking acne progress.

Which acne tracker apps are worth comparing?

Seven apps cover the jobs most people want from an acne tracker: scored or dated photos, a way to log possible triggers, and some form of trend view. Prices are the in-app purchase ranges shown on each US App Store page in October 2026; they vary by region and change often.

What should an acne tracker app actually do?

An acne tracker should help you answer one question at a time: is this treatment working, or does this habit make my skin worse? Three features matter most.

• Comparable photos. A 2023 study by Cronin and colleagues found that changing a smartphone's distance and angle shifted the measured color of skin-tone standards, and that flash didn't reliably fix it. If your setup changes, the app's comparison changes with it.
• A trigger log you'll keep up. The American Academy of Dermatology (AAD) says acne may worsen if you get too little sleep, eat certain foods or use oily makeup and skin care, and that stress can worsen existing acne. A tracker that logs these in a few taps gets used.
• A timeline measured in weeks. The AAD says that if an acne treatment works, you should notice some improvement in 4 to 6 weeks, and clearing can take two to three months or longer. Apps that show week-over-week trends fit that reality better than daily scores.

The acne tracker apps, one by one

1. Pori: Skin Face Age Checker

Pori turns a selfie into an overall skin score from 0 to 100 in about 10 seconds, with sub-scores for hydration and moisture, pores and texture, pigmentation and tone, anti-aging and elasticity, and overall health. It reads the face region by region using a 468-point face mesh. The skin diary logs sleep, water, stress and diet, so you can set your scores against your habits on the progress charts. Before-and-after comparison, streaks, reminders and a home-screen widget help you keep a steady schedule, and an AI chat can answer questions using your scan history. The ingredient scanner (Pro) flags each ingredient in a product as beneficial, use with caution or avoid for your skin type, which helps when you suspect a new product.

Where others are stronger: Pori has no dedicated acne or redness score, so Skinsign, Puffin and Trace measure breakouts more directly. Its diary doesn't have a field for your cycle or a food barcode scanner. It's iPhone-only (iOS 17 or later). Pori is a wellness app, not a medical device, and doesn't diagnose acne. Photos are sent over HTTPS for analysis and aren't kept on Pori's servers after the result; your history stays on your phone.

2. Skinsign: Acne Coach and Scanner

Skinsign is built around the idea that breakouts follow patterns in your habits. A face scan gives four scores (acne, redness, texture and hydration), and a daily log covers food, sleep, stress and water. Its food scanner reads a barcode or ingredient label and flags items such as added sugar and dairy. A "Correlation Engine" looks for which habits line up with your clearer and rougher days, and you can compare before-and-after photos side by side. It had 217 ratings averaging above 4.5 when we checked.

Watch out for: the listing says it's a wellness tool, not a medical device. Diet research on acne is still limited, so treat a food flag as a prompt to test, not a verdict.

3. Puffin: Acne Tracker

Puffin gives you a single skin score built from acne, texture, tone, hydration, pores, redness and more, and tracks it week to week. Its most distinctive feature for acne is zone tracking: it shows which areas (nose, cheeks, forehead, chin, temples) flare most often. It also has morning and night routines, reminders, streaks, a product and ingredient search and an AI skincare assistant.

Watch out for: Puffin requires a subscription to access all features, with a 3-day free trial on the annual plan. The listing says it's for educational use and doesn't give medical advice.

4. Trace: Acne and Skin Tracker

Trace is the most experiment-minded app here. A daily selfie becomes four scores from 0 to 100 (acne, redness, pores and spots), and the app encourages you to change one product or habit at a time and watch the line over weeks. You tell it what you ate, how you slept, whether you were stressed, traveling or on your period, and it sets those notes against your trend. Its listing says the scores are measured on your iPhone, so scanning doesn't send your photo anywhere; optional AI features send a photo only when you use them.

Watch out for: Trace is new, with 13 ratings when we checked, and needs iOS 17 or later. No in-app purchases were listed.

5. AcneTrack

AcneTrack starts with a questionnaire about your skincare and lifestyle, then gives you a plan with skincare, nutrition and lifestyle suggestions and tracks progress trends as you follow your routine. It had the largest rating count of the acne-specific apps here, 904, averaging above 4.5.

Watch out for: its listing doesn't describe photo scoring or a trigger correlation feature, so it's more of a routine coach than a measuring tool. Premium features require a subscription, and the app says it is not a diagnostic tool.

6. Clear: Social Skincare Tracker

Clear keeps routines, products and progress photos in one place. You can take private progress selfies from multiple angles and compare them across days, weeks and months, build AM and PM routines from a database of more than 30,000 products, and optionally share updates with a skincare community. Sharing is off unless you choose it.

Watch out for: Clear doesn't score photos or log lifestyle triggers, so you'll be judging changes by eye.

7. Bearable (a general tracker you can adapt)

Bearable is a general symptom tracker rather than a skin app, and it's the most flexible trigger log here. You can add "breakouts" as a symptom and rate it daily, then see correlations with sleep, food, stress, medication, weather and your cycle. It syncs steps, sleep and heart rate from Apple Health and Fitbit, and had more than 6,500 ratings when we checked.

Watch out for: there's no photo tracking, so pair it with a photo app. Its insights are correlations, and the listing says they aren't medical advice.

Can an app tell if acne is hormonal or caused by food?

No app can tell you the cause, but a log can show whether a pattern repeats. In a survey of 400 female patients published in the Journal of the American Academy of Dermatology, 44% reported premenstrual acne flares. If your breakouts cluster at the same point in each cycle for several months, that's useful to show a dermatologist. Our guide to tracking your skin across your cycle explains how.

Food is harder. The AAD notes that small studies link high-glycemic diets and cow's milk to more acne, and that more research is needed. Its advice is to watch whether a food seems to trigger breakouts and see what happens when you skip it for a day, a week or a month. A tracker makes that test easier to read.

How do you log acne so the data means something?

Use the app like a simple experiment. This routine works with any of the apps above.

1. Pick one question. For example: does this new cleanser help, or do my breakouts follow my cycle?
2. Take photos the same way each time. Same spot, same light, same time of day, clean face, no filters. Front, left and right views.
3. Log a few triggers daily. Sleep, stress, your cycle and anything new on your skin. Fewer fields logged every day beat many fields logged twice.
4. Change one thing at a time. Give a new treatment at least 4 weeks before judging it, as the AAD recommends.
5. Read weekly trends, not daily scores. One bad day is noise; a three-week climb is a signal.

Which acne tracker should you choose?

• You want scores plus a lifestyle diary in one iPhone app: Pori, with Skinsign as the closer fit if food is your main suspect.
• You want acne measured directly: Skinsign, Puffin or Trace, all of which score acne or breakouts specifically.
• You want to run careful one-change experiments without paying: Trace.
• You mainly want a private photo log and product list: Clear.
• You want to track many possible triggers, including your cycle: Bearable, paired with a photo app.

When should you see a dermatologist instead of tracking?

Tracking helps you manage mild acne and judge over-the-counter products, but it isn't treatment. The AAD suggests seeing a dermatologist if you've tried everything and nothing works, you have deep, painful cysts or nodules, you see scars or dark spots as acne clears, your acne started after a new medication, or acne is affecting your mood. A few months of dated photos and notes from any of these apps can make that appointment more productive. None of these apps, Pori included, diagnoses acne.
