AcnePilot vs Preen

Build a clearer picture of your skin—one routine, check-in, and photo at a time. With AcnePilot, you can organize your skincare routine, record how your skin feels, and review your progress over time. Everything is based on what you choose to log, without automatic diagnoses or claims about what caused a change. CREATE YOUR ROUTINE Build and edit morning and evening routines, choose the days for each step, and keep your skincare products organized in one place. RECORD SKIN CHECK-INS Track breakouts, redness, marks, texture, hydration, and how your skin feels overall. You can also add notes and optional context such as stress, sleep, and water. KEEP A PHOTO JOURNAL Save progress photos from your camera or photo library. An on-device alignment guide can help you keep your position and distance more consistent when taking new photos. REVIEW YOUR PROGRESS Explore your history through a calendar and timeline. Review your routines, photos, and check-ins, or compare two recorded moments side by side. OBSERVE PRODUCT CHANGES Use Product Trials to focus on one product change at a time. Record whether you followed your plan, note reactions, and write daily observations or a final summary. STAY CONSISTENT Set local reminders for your morning routine, evening routine, and weekly progress photo. Routine streaks help you recognize the days when you showed up for yourself. ASK THE SKIN GUIDE Ask general skincare questions about your routine, products, or how your skin feels. You decide what information to send and whether to attach a photo. PRIVACY BY DEFAULT Your profile, routines, products, check-ins, notes, trials, and progress photos are stored locally on your iPhone by default. AcnePilot does not require an account and does not automatically sync your tracker data. Information leaves your device only when you choose to send a Skin Guide request. A photo is included only when you explicitly attach one. IMPORTANT INFORMATION AcnePilot is a personal tracking and educational tool. It is not a medical device or healthcare service. It does not diagnose skin conditions, prescribe treatments, or prove that a product or event caused a change in your skin. For medical concerns, diagnosis, or treatment, consult a qualified healthcare professional. AcnePilot is intended for adults aged 18 and over.
