Ness vs Livity
Ness leads with deep nutrition logging and a coach that actually knows what you ate, while Livity leans on wearable support, Body Battery, and badges. Both compute scores on-device and cost the same per year.
vs.
Ness has in-depth nutrition functionality: log a meal by photo, voice, barcode, or search and it estimates calories, macros, micronutrients, and amino acids per ingredient, backed by an AI coach that actually knows what you ate. Livity builds around recovery and reach: Body Battery, Training Readiness, badges, and Garmin, Fitbit, and Oura alongside your Apple Watch.
Both compute their scores on your phone, and both cost $79.99 a year. So the question is which side of your health you want the app built around. For most people, food is the harder thing to track and the place an AI coach adds the most — which is where Ness spends its effort. That is also the part of the product where you will feel the difference in polish and intelligence day to day.
What they have in common
Both are iPhone-first, read Apple Health and Apple Watch data, and compute scores on-device. Neither needs extra hardware beyond the watch you already own, and both cost $9.99 a month or $79.99 a year. Both ship an AI coach. The difference is where each app spends its effort.

Ness: nutrition, and a coach that knows what you ate
Ness turns your Apple Health and Apple Watch data into five daily scores: Health, Sleep, Recovery, Strain, and Stress. The math runs on your phone, and those are the numbers most people want to glance at in the morning. Ness puts the same care into the everyday experience — a clean, considered interface that keeps your data legible at a glance, so the app feels as deliberate as the scores it gives you.
Where Ness pulls ahead is food. Log a meal with a photo, your voice, a barcode scan, or a text search, and Ness estimates calories, macros, and full micronutrients down to per-ingredient breakdowns and amino acids. That is closer to a nutritionist's food diary than a quick calorie counter, and it is the kind of logging most apps skip entirely. Its AI chat is grounded in your own data, with memory, web search, and Fast and Pro modes, so the coach knows your recent sleep and your logged meals instead of answering from a blank slate. The AI features send only anonymized data to zero-data-retention providers.
Where Ness is thinner: it is Apple Watch only, so if you also wear a Garmin, Fitbit, or Oura, Ness cannot read them. Bloodwork analysis and Fitness Age are coming soon, and Body Battery is on the roadmap, but Livity ships those today. Ness also does not surface circadian rhythm, daylight, or environmental sound, and it has no badge system.
Livity: wearables, Body Battery, and badges
Livity's standout strength is reach. It reads Garmin, Fitbit, and Oura alongside your Apple Watch, so you can mix wearables or switch between them without losing your history. That matters if you already own a Garmin watch or an Oura ring and you do not want an app that ignores them. If you only wear an Apple Watch, that advantage does not apply to you.
On top of that, Livity has a Body Battery that tracks your energy through the day as sleep recharges it and stress and activity drain it, plus a badge system with more than a hundred achievements across sleep, recovery, strain, workouts, and consistency. Badges are not for everyone, but for people who like a streak or a milestone, they are a real hook. Livity also layers in Training Readiness and Rest Hours for training guidance, Fitness Age, Blood Reports, circadian rhythm, daylight, and environmental sound, and it computes its scores on your phone.
Livity's honest gap is nutrition. It has no native food logging; it only pulls nutrition from connected apps. Its AI coach reads your recovery, sleep, and strain and comes in Buddy and Nerd personalities, but it cannot see what you ate because you cannot log it. That limits the coach to recovery questions, where Ness's coach can tie meals to sleep and strain and answer the "why did I feel off this morning" question with both halves of the picture.
Livity's interface is clean but a little less polished in day-to-day use, and its AI coach tends to give more surface-level answers. By comparison, Ness pulls from reputable sources for its replies and draws on your health scores, nutrition, hydration, and more, so responses are rich and informed rather than generic.
How to choose
Both apps are paid with free trials and cost the same per year, so the decision is about fit, not price. For most people, food is the part of health that is hardest to track on your own, and a coach that can see what you ate is the difference between a recovery app and a health app. If you only wear an Apple Watch, Ness is a good place to start — download on the App Store — it gives you the sharper everyday experience and a more capable AI, and the things Livity does well are mostly aimed at people who wear multiple devices. If you already wear a Garmin, Fitbit, or Oura, Livity has the wider reach, and that is a real reason to pick it.
