What is Acnera?
Acnera is an acne and skin tracker app for iPhone. It uses AI face scans to give you a skin score and acne severity, scans skincare product ingredients for fit and conflicts, and tracks habits like water, sleep, stress, and your cycle so you can see what is actually triggering your breakouts.
Is Acnera free?
Acnera is free to download on the App Store. Acnera Pro unlocks the full experience and is available as a weekly, monthly, or annual subscription, and the annual plan includes a free trial. You can cancel anytime in your iPhone Settings under Apple ID, then Subscriptions.
How does the AI acne scan work?
Take a photo of your face in the app. Acnera estimates your acne severity and skin score, highlights visible features like clogged pores, redness, uneven texture, and dark spots, and breaks the results down by zone: forehead, left and right cheek, nose, chin, and jawline.
Can Acnera tell me if a skincare product will break me out?
Scan a product and Acnera reads its ingredient list, gives you a verdict on how well it fits your skin, and explains what it works best for and when it is not ideal. It also flags overlaps with products already in your routine, such as stacking several strong actives. Treat it as guidance, not a guarantee.
What can I track besides my skin?
You can log water intake, sleep, stress, energy, and your menstrual cycle, plus check off your AM and PM skincare routine. Acnera builds streaks to keep you consistent and compares these habits against your skin score over time, so you can spot which triggers matter most for you.
Does Acnera replace a dermatologist?
No. Acnera is a tracking and education tool, not medical advice, and it does not diagnose conditions. Many people use their before and after photos and trend data to have a more productive visit with a dermatologist. If your acne is severe, painful, or scarring, see a professional.
Is my skin data private?
Your photos and skin data are used only to power your own analysis and are never sold. You can delete individual photos and logs at any time, and deleting your account permanently removes all of your data, including face images.
What do I need to use Acnera?
Acnera runs on iPhone with iOS 17.6 or later. Download it free from the App Store, answer a few questions about your skin, and you will have a personalized goal and your first skin scan in about two minutes.
