CalTrak: Calorie Tracker

CalTrak is a calorie and macro tracker for iPhone. Log a meal by barcode, search, photo, or quick description. Watch your day take shape on a clean ring. See your week, month, and quarter at a tap. Everything stays on your device — no account, no subscription, no ads.

Completely free. No ads, subscriptions, accounts, or paid features. CalTrak includes an entirely optional one-time tip jar for anyone who wants to support development. Tips unlock nothing and are never expected.

FIVE WAYS TO LOG A MEAL
• Scan a product barcode — pulls nutrition straight off the label
• Search across Open Food Facts, FatSecret, and USDA FoodData Central
• Describe a meal in your own words ("chipotle bowl, double chicken, sour cream") for an AI estimate
• Snap a photo of a nutrition label, restaurant menu, or your plate — works with camera, photo library, or clipboard paste
• Enter a custom food in any unit: grams, ounces, cups, milliliters, servings, pieces

PERSONALIZED TARGETS
• Goal wizard uses the Mifflin-St Jeor equation plus your activity level to compute daily calorie and macro targets
• Higher protein during weight loss; sensible safety floors built in
• Re-runnable anytime — your last inputs are remembered
