Description by Marcus Spitzmiller (from the App Store)

OneCal is a science-based calorie tracker for people who don’t want to think about weight loss—they just want to do it. No macros to calculate, no barcode scanning, no friend feeds, no badges. Enter the calories that you eat, see your target, and move on. It’s calories in, calories out—fast to log, simple to follow—so you can spend less time in an app and more time living your life.

This app provides general information only and is not medical advice. Consult a qualified healthcare professional before making changes to your diet or exercise. OneCal does not diagnose, treat, cure, or prevent any condition and disclaims liability for decisions made based on app data.
