About
Lifesum is an AI-driven nutrition and healthy eating app designed to empower individuals with the knowledge and tools to make smarter food choices. At its core, Lifesum offers multimodal meal tracking — users can log food by snapping a photo for instant AI-powered nutrition recognition, speaking hands-free, typing manually, scanning barcodes, or using quick-entry shortcuts. This flexibility makes consistent tracking realistic for any routine. The platform delivers a comprehensive breakdown of macronutrients (protein, carbs, fats) and micronutrients (sugars, fiber, saturated fats), allowing users to fine-tune their intake based on personal goals. Whether the aim is weight loss, muscle gain, better sleep, improved energy, or longevity, Lifesum offers curated Meal Plans and Diet programs — including Keto, Mediterranean, Fasting, and Protein Weight Loss — to guide every step. Beyond tracking, Lifesum helps users build lasting habits with one-tap water, fruit, and vegetable intake trackers, as well as a points-based engagement system that rewards healthy choices. Syncing with Apple Watch and Samsung Galaxy Watch brings passive activity data into a unified health picture. With a database of millions of food items accessible via barcode scanning, personalized weekly advice, and a clean interface praised across 920,000+ reviews, Lifesum is ideal for health-conscious individuals, fitness enthusiasts, and anyone looking to develop a sustainable, informed relationship with food.
