ItchLog is a diary for eczema-prone skin. Tap where it itches on a body map, and log what you ate and how your day went alongside it. As your logs build up, you can compare what happened on the days your skin changed.
■ Log right on a body map
• Tap any spot on the front or back body map to mark it
• Tap again to switch between mild, moderate and severe
• Long-press a mark to attach a photo of that exact spot
• Same as yesterday? Bring yesterday's marks back with one tap
■ Meals and daily life, side by side
• Log what you ate at each meal, with foods you eat often suggested instantly
• Check sweat & workouts, gut condition, moisturizing, hot showers, new skincare and detergents
• Pollen, alcohol, pets, dust, secondhand smoke, wool & synthetic fabrics, travel and nights away
■ Data that logs itself
• Apple Health: sleep, workouts and steps
• Weather: temperature, humidity, UV index and air quality (AQI)
■ Compare foods and habits
• From your last 90 days of logs, see how your skin logs looked on days with and without each food or habit
• All calculations happen on your device
■ Look back anytime
• Tap a day on the calendar to review or edit its body map, meals and photos
• Optional once-a-day reminder
■ Peace of mind
• No ads
• Sign in with Apple, Google or email, and your logs follow you to a new device
• Delete your account and all your data anytime in Settings
Note: ItchLog is a logging tool and does not provide diagnosis or treatment. Comparisons are observations, not causes. If you're concerned about your symptoms, talk to a healthcare professional.
