What I think is... this module transmits data to a cell phone. Your phone or a phone takes that data and the app assembles it as, RPM's, GPS, MPH or what ever information your looking for or asking for. It sends it to the cloud and stores it so you can downloaded to your device of choice but I think it needs a phone to store the data or at least retrieve the data from the unit installed on the motor. I don't think it will store the data.
Like I said this is guess work on my part and likely I'm wrong, lol. I've been in the business for 40 years and have been wrong more than right, hey I worked for Nortel, bahaha. I do think this requires more looking into and I am looking into installing it on my boat, love stuff like this, thanks for the post.
