    1. With the web API, you can only pull data at rest, meaning you'll need to sync your Sense to the Fitbit app before you can fetch the data. The endpoint you'd use to fetch this data is the Intraday Heart Rate Time Series endpoints. If you'd like to test this endpoint, you can do it with the Fitbit API Explorer.    If you're looking to fetch real-time/raw data with 1sec detail level, you'll want to use the Device API and SDK to create a clock face. You can get further assistance from other developers and our moderators in the SDK forum here.

    1. You could use our algorithm and any PPG/ECG sensors to get the raw data .Ours can clean up noisy signals and gives you raw PPG/ECG data

    1. Heart Rate Monitor LED Green Sensor The Heart Rate Monitor (HRM) LED green sensor measures the amount of green light that is reflected back from a person's blood vessel. The following table lists the measurement data that the HRM LED green sensor provides.

      Tizen API accessing amount of green, red, and IR light reflected from a blood vessel

    1. Wear OS is a smartwatch operating system created and maintained by Google. It was announced on March 18, 2014 as Android Wear, only to be rebranded as Wear OS on March 15, 2018. Wear OS is an Android-based operating system that receives semi-regular feature and security updates, just like the version of Android that powers billions of smartphones around the world.

    1. The data is queried directly from your Fitbit account and inserted into Google Fit. To do this, you must first log in with your Fitbit account and give FitToFit access to the data that you want to transfer. You will then be asked to connect to your Google account, into which the data from Fitbit should be inserted.

      Cannot directly interface with fitbit with Google fit, can only export processed data from fit bit and send to google fit...

    1. The Google Fit APIs for Android are part of Google Play services. The Google Fit APIs are supported on Android 4.1 (API level 16) and higher. Using these APIs, your app can do the following: Read near-real-time and historic data, including data from Bluetooth Low Energy (BLE) devices. Record activities. Associate data with a session. Set fitness goals.

      Google Fit API for Android allows raw data access!!!

    1. Sensors API

      Fit bit's sensor API... only preprocessed data and not raw. Fit bit does not use Android API for sensor access..

    1. As mentioned before, sensors such as the Empatica provide some raw data (E.g. raw PPG), although the cost is very high (around $ 1700 US). Moreover, smartwatches such as the Moto360 or the LG G Watch R can be programmed to provide HR data. However, you should consider that this is preprocessed data (from manufacturers) and we just have access to the processed data (not the raw PPG). Therefore, if you wanted to make things such as Heart Rate Variability analysis, this approach is not highly accurate. I have been working with the Polar Chest Band (H7) and it seems that we can access both HR and RR-interval data with an Android app (currently working in an APK to extend it in our PhysioVR framework).

      Thread on finding devices that provide raw data

    1. Access raw sensor databookmark_border Table of contentsList available data sourcesAdd a listenerRemove a listener The Sensors API lets you read raw sensor data in your app in real time. Use this API to do the following: List data sources that are available on the device and on companion devices. Register listeners to receive raw sensor data. Unregister listeners so that they no longer receive raw sensor data.

      Google fit allows access to raw sensor data

    1. Depends on vendor, it would be possible to access the raw ppg signal of wear os sensor, should you have access to sensor hardware driver. Some researchers did analysed PPG raw signal from Huawei watch 2 and here is the paper.

      android /wear OS allows for raw PPG data access, but need drivers...

    1. Each Fitbit device includes a variety of hardware sensors that have been exposed through our Sensor APIs.

      No info on PPG sensors... not accessible through API?

    1. Unfortunately this is not available via an API at this time.

      Unable to get fitbit ppg through web api? from 2018

    1. This is a simple application I slapped together for the heart rate data that I captured here from the Apple Watch.

      Code for accessing heart rate data from apple watch, from 2015

    1. Third party apps do not have direct access to the heart rate sensor.

      Thread that explains how to access heart rate data by simulating a workout... No direct way to access sensor

    1. Retrieve data and derived metrics from an iPhone’s sensors, or from a paired Apple Watch.

      SensorKit API

    1. You can use HealthKit and have your app request access to the Blood Oxygen data (HKQuantityTypeIdentifierOxygenSaturation)You can find out more about the HealthKit framework here: https://developer.apple.com/documentation/healthkit

      Response from Apple employee when asked about retrieving raw PPG data.. Need to use HealthKit and can only get processed data

    1. as far as I know there is no way to access the raw PPG from the watch

      No way to access raw PPG data from apple watch... this guy has an app that does some processing on the data from apple..

    1. A Flutter plugin to access the PPG sensor.

      Assists with accessing PPG data for android watches

    1. 7 This answer is not useful Show activity on this post. I spent some time figuring out if it's feasible to get the raw PPG signal from android API, and contrary to what some may say, it is definitely possible to do that. And here is how to do it:
