Lifesum

Lifesum is a nutrition and healthy-eating app that uses AI to make food logging fast and personalized for a large global user base.

Its multimodal tracking lets you log meals by photographing food for instant nutrition data, using voice commands, typing details, scanning barcodes, or quick-tracking, so logging fits how you prefer to work.

It provides detailed macro breakdowns including protein, carbs, and fats, plus subcategories like fiber, sugars, and saturated fat, and offers lifestyle-specific meal plans such as high-protein weight loss, Mediterranean, fasting, and keto.

It is aimed at people who want to build healthier eating habits, manage weight, or hit specific macro targets with minimal logging friction.

Core features include a barcode scanner covering millions of items, one-tap trackers for water, fruit, and vegetables, wearable integration with Apple Watch and Samsung Galaxy Watch, weekly insights, and personalized recommendations.

Typical use cases include tracking daily intake against a goal, following a structured eating plan, and reviewing weekly nutrition trends. Pros: very flexible logging options, a polished and approachable interface, and helpful meal plans and insights.

Cons: the most useful plans and features sit behind a premium subscription, and AI photo estimates, like all such tools, are approximate rather than exact. Lifesum supports nutrition and lifestyle goals and is not a substitute for professional medical or dietetic advice.

Pricing changes often, so check the official site for current plans.
