I'm trying to develop an app for a fitness tracker(can be any), which has an API to track the live hand movements (For every couple of seconds). To be specific, trying to find aggressive hand movements to track users who need help (like seizures, under attack by someone etc.,) and alert the friends/family.
Can anyone suggest a fitness tracker which has such API exposed? Learned that FitBit don't have such API exposed.
You do not get raw data from the fitness trackers. Here is an article about it.
In short it says:
Fitbit: No access to minute-by-minute (intraday) data with public API, only with Partner API (needs approval by fitbit)
MisFit: No access to minute-by-minute data (intraday) with API. There’s only a summary for each day available.
Jawbone: The Jawbone API provides a nice endpoint called ‚moves‘ for hourly data as well as intervals every minute or even 10 seconds (for defined workouts)
Withings: No access to minute-by-minute data without activation through Withings (request needed)
Garmin: Getting detailed information about the Garmin API is quite difficult. It seems that the only option to get access to tracker data, is to get access to all data from end users worldwide ($5,000 One-time License Fee).
Sony: Sony only grants access to tracking data through the Lifelog API. You can therefore read all of the extra lifestyle data you logged besides the movement data. Could get bulky, but you got the possibility, if you like. You can recall the tracked activities via API, subdivided in minute-by-minute data.
You could try to find a device which supports the FitApi from Google (Android Wear device). It supports access to raw sensor data (Example).
