I have tried it, and it seems a good demonstration. But I also need to collect user's data for analysis. This app only gives you the count on screen. I can't get any data from this library.
So, is there anyone need to do this as me? I think I can pay for that if someone who can help me to wrap java as a b4a library. Such as an event to post data when detecting a heartbeat, and I will count it myself.
