Nutemi

Nutemi is an AI nutrition companion that logs meals through photo, voice, text, or barcode scanning and tracks calories, macros, vitamins, minerals, and hydration. It differentiates itself with a conversational format: users can talk to Nutemi like a coach, and the AI reacts with eight distinct daily moods based on meal quality, hydration, and nutrient balance rather than presenting a plain dashboard. Beyond tracking, the app builds meal plans and food diaries, offers BMI monitoring, and supports fasting schedules. It launched in 2025 and is free to download with subscription plans required to unlock the full coaching experience.

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.
