About

ReceiptCal

Read full description

ReceiptCal logs food automatically from supported restaurant and delivery receipts. Use your private @receiptcal.com address at checkout, or forward food receipts. Estimated calories and macros appear in your log after processing. No searching for each item. No meal-by-meal typing. YOUR DAY, ADDED UP See meals, calories, protein, carbs, and fat in one place. Adjust a portion or ignore an item when needed. Sources stay in the meal details. MORE WAYS TO LOG Photograph food or scan a packaged-food barcode. Ask voice for recipe ideas, reuse a suitable community recipe or create something new, and log a serving when you eat it. Ask voice to add what a recipe needs to your Sprouts cart; it skips what's in your pantry, and you check out with Sprouts. OPTIONAL HEALTH SYNC With your permission, logged nutrition syncs to the Health app when ReceiptCal syncs. ReceiptCal does not read your Health data. YOUR INBOX STAYS YOURS No personal-mailbox access. ReceiptCal only receives email sent to your private receipt address. You can delete your account and stored meals in the app. Nutrition values are estimates for everyday tracking, not medical advice. Portions and preparation vary. Some items may not resolve.
