We are made of food. Literally — our cells are assembled from the molecules we ate yesterday. That's nutrition. Then there's how we use the energy those cells produce — that's activity. Then there's the fact that when we sleep, our body doesn't rest. It regenerates. That's recovery. And water — water is consumed by our body every second, it's the last necessary ingredient in producing energy. We need enough of it, and we need it at the right time. Drink before bed and you'll get up to pee, because your body needs to dump the excess and get back to regenerating. These four things — nutrition, activity, sleep, hydration — can't be separated from each other. Eat too late and you can't fall asleep. Sleep badly and you wake up with no appetite, and your workout is garbage. Come back from a late workout and you can't wind down. It's one system. Your personal health runs on it. I called it NASH. Four letters, four pillars. That's everything your body needs for daily health rehabilitation. Here's where it gets interesting. Every morning — has to be morning — you check in with your AI health agent and rate how yesterday went across those four. While you're scoring, your brain automatically replays the day. You remember what went well and what didn't. And you're honest with yourself, because your health data stays private — nobody else sees it, ever. How you feel is usually more important than what instruments show. That reflection does something I didn't plan for. By reviewing yesterday every morning, you subconsciously set up today to be better. You don't need motivational quotes. You don't need push notifications. The act of honestly looking back is enough to change what comes next. Reflection is maybe the only real mechanism of change — reflecting on yesterday helps you live tomorrow differently. After you check in, NASH shows your personalized task for the day and a health tip — backed by a specific study you can read. One thing. One day. That's the daily health protocol — reflect, get your task, go live. Behind the scenes, NASH reads your Apple Watch data — heart rate, HRV, sleep stages, activity — combines it with your self-assessment, weighs each signal differently, and calculates your health score, biological age, cardiovascular age, projected healthspan, and how many healthy years you have ahead at this trend. Raw sensor data doesn't measure how you feel. Your subjective rating doesn't know your HRV. NASH uses both, and tracks how both change over time. That's where the real picture of your health emerges. After just 4–7 days, something shifts. You become a little more aware. A little more honest with yourself. Maybe a little healthier. We're not touching the spiritual side of life here — just the biological machine. And the biological machine only needs four inputs. NASH is for educational and wellness purposes only. It is not a medical device and does not provide diagnosis or treatment.

Rest smarter. Recover faster. ### 1.0.9 — 2026-07-18 Your score, refined. We continuously improve the algorithms behind your Longevity Score — adjusting how NASH weighs your biometric and activity signals so the number you see each morning is as close to reality as possible.

Your daily check-in just got a little more honest. ### 1.0.8 — 2026-07-02 The details that make a habit stick. This update polishes the everyday experience of using NASH — smoother animations, clearer metric descriptions, and small design refinements that make your daily check-in feel more natural.

Just your data, working for you. ## More apps by Pavel Hrybouski - [exampeak: MAX brain readiness](https://appshunter.io/ios/app/exampeak-max-brain-readiness/id6761715722) All apps by Pavel Hrybouski: https://appshunter.io/developer/1876672237 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
