FWIW, I still use the Zeo App w/ a dedicated iPhone 4 w/ iOS 5.x.x.
It exports data via email, which is visible by Woody’s PC (Mac or Win) App.
Woody to the rescue
Thus, if you think Intel/Basis provided everything you need, give it a shot, but I would dedicate an iOS 9.3.x to the App/Device if you’re serious.
