Yes it could be faster because that’s always better, especially for those with slower devices. It’s quite an intensive application though. I agree with the above comment that maybe stuff could be loading while doing the sensor pairing or logging in part.
The slowest part for me is getting to the “Let’s Go” screen though. I’m on a very fast computer but that screen takes about 10 seconds to appear after clicking the icon but is only a white box for another 15 seconds or so before the buttons even appear. Sometimes I wait for 45-60 seconds before the white box just disappears and I get a no-internet-connection message (my internet is fine though).
