Track this in NYUS. NYUS reads steps, sleep, heart rate, workouts, calories burned and weight through Health Connect on Android; resting heart rate, HRV, blood oxygen and breathing rate only if you turn on health alerts.
Join the NYUS waitlistNo: Health Connect is not a workout app. It is the Android store where apps share data you allow (Google).
| Google data category | Examples Google lists | What NYUS (our app) reads |
|---|---|---|
| Activity | steps, distance, exercise, total calories burned | steps, workouts, calories burned |
| Body measurements | weight, body fat | weight (and it writes back only the weights you log) |
| Vitals | heart rate, resting heart rate, heart rate variability | heart rate (resting heart rate, HRV, blood oxygen and breathing rate only if you turn on health alerts) |
| Sleep | sleep session | sleep |
A workout tracker reads and writes steps, exercise, heart rate and weight there under App permissions. Which data types an app uses is up to the app and you; the full list of seven categories and the setup steps are below.
General information: This page is general information, not medical advice. No dietitian, doctor or qualified trainer has reviewed it, and it is not a substitute for their advice.
Health Connect is the Google platform on Android where health and fitness apps store and share data, with the user choosing which app can read or write which data type. This guide explains what it is, what data types it lists, how to connect an app, and what NYUS does with it. Every Google statement below is from Google's own pages, linked under Sources.
Short answer: Health Connect is the Google platform on Android where fitness apps store and share health data, and you choose which app may read or write which data type. It runs on Android 9 or higher: it is built into Android 14 and higher, and on Android 13 and lower you install it from Google Play. To control an app, open Health Connect and go to App permissions (Google, developer.android.com, read 26 October 2026).
Google's developer documentation says Health Connect "stores and structures health and fitness data" and that apps use it with the user's permission. On Android 14 and higher it is part of the Android framework; on Android 13 and lower you install the Health Connect app from Google Play, and the app works on Android 9 or higher (Google, developer.android.com, read 26 October 2026).
On privacy, Google's launch post (May 2022) said "the data in Health Connect is all on-device and encrypted" and that users can shut off an app's access or delete data they do not want on their device. That is a 2022 statement of design, so check Google's current help pages for how it behaves today; this page is not a security guarantee.
Google's data types page groups Health Connect data into seven categories. Names below are as Google lists them (read 26 October 2026); the page states no total, so we give none.
| Category | Data types listed by Google |
|---|---|
| Activity | Active calories burned, activity intensity, cycling pedaling cadence, distance, elevation gained, exercise, floors climbed, planned exercise, power, speed, steps, steps cadence, total calories burned, VO2 max, wheelchair pushes |
| Body measurements | Basal metabolic rate, body fat, body water mass, bone mass, height, lean body mass, weight |
| Cycle tracking | Basal body temperature, cervical mucus, intermenstrual bleeding, menstruation flow, menstruation period, ovulation test, sexual activity |
| Nutrition | Hydration, nutrition |
| Sleep | Sleep session |
| Vitals | Blood glucose, blood pressure, body temperature, heart rate, heart rate variability, oxygen saturation, respiratory rate, resting heart rate, skin temperature |
| Wellness | Mindfulness |
Which of these a given app reads or writes is up to that app and to you; Health Connect shows the permission for each type.
The idea is that apps read and write one store instead of each keeping its own copy, so a fitness app can show steps and sleep next to your workouts. What an app then does with the data differs by app, and reading a number is not the same as changing your plan because of it. NYUS reads steps, sleep, heart rate, workouts, calories burned and weight from Health Connect (plus resting heart rate, HRV, blood oxygen and breathing rate if you turn on health alerts), and writes back only the weights you log. Its weekly check-in adjusts your calories, macros and step goal once enough is logged; it does not change your training plan automatically.
Two founder notes on what a tracker does not see even with shared data: the rest day your tracker cannot see and the PR you did not log.
On Android 14 and higher Health Connect is built into the system; on Android 13 and lower, install the Health Connect app from Google Play (Android 9 or higher). The setup steps:
The permission screen shows exactly which data types an app asks for, so read it before you accept.
We do not keep a list, because integrations change and some apps use only a few data types. The App permissions screen in Health Connect shows which of your installed apps can connect, and each app's own page says what it reads and writes. Google's documentation says the Google Fit APIs "will be supported until the end of 2026" and links a migration guide to Health Connect.

Connect NYUS to Health Connect and your steps, sleep, heart rate, workouts, calories burned and weight come in from your wearable without manual logging (resting heart rate, HRV, blood oxygen and breathing rate only if you turn on health alerts).
