Help with fitbit devices that support certain readings

[huyqtran1111]

Greetings,

I'm totally new to our fitbit community and would like to develop an application for fitbit devices.

The current data I would need access to is heart rate, oxygen level, and accelerometer. I know most fitbit devices support the first twos, for example luxe and inspire 3, but I cannot find any information regarding accelerometer, or depth-related reading. I've been looking up the comparison between devices, but none show accelerometer capability. Very confusing reading outside resources as well.

So my question is: which fitbit devices support all of these readings, especially accelerometer? 

Thank you!

Here's the link to the comparison mentioned above

Are you wanting to use the Web API or the SDK?

Thank you for your quick response @Gondwana 

I'm thinking to start with the SDK and test a few things out. Also aim to make this app a real-time one as well. Any suggestion for me is totally welcome

SDK is the only choice if you want real-time. SDK can get you heart rate and accelerometer, but not SPO2. SDK can only be used with Versa 1/2/3 and Sense 1. Versa 4 and Sense 2 support might come.
