Overview
Description

Carb Manager is a nutrition-tracking app built specifically around ketogenic and low-carb eating, with a food database of over a million items and more than 5,000 keto-friendly recipes built in. It supports logging food by barcode scan, voice input, or manual search, and tracks not just calories and macros but advanced metrics like ketones, blood glucose, and the Glycemic-Ketogenic Index for users monitoring metabolic health closely. Premium features add personalized weekly meal plans, an automatically generated shopping list from those plans, and photo-based food logging, along with device syncing to Fitbit and Garmin. A free Keto Academy and active community forum round out the app for people who are new to low-carb eating and want structured guidance alongside tracking.

Cronometer is a nutrition and diet tracking app that goes beyond basic calorie counting to monitor macronutrients and up to 95 vitamins, minerals, and other micronutrients. Food can be logged by barcode scan, photo, voice, or text search against a database of more than one million verified foods, and results sync with devices like Fitbit, Apple Health, Garmin, and Oura.
