The old app was as perfect as the user wanted. A quick glace was all that was needed most of the time. Most of the information was visible without scrolling. Min and max data was displayed without having to open a box. Now, you have to scroll to find anything and click open many boxes to see the data that used to be visible with little effort.
This is deja vu for former Fitbit users. Fitbit was purchased by Google. Google set out to destroy Fitbit by forcing on the Fitbit users a new app that was hard to navigate and making it very difficult to find the data that the users wanted to see. Most of the Fitbit users hated the change. The result is the Fitbit users are migrating to either Garmin or Apple or some smaller players. Being one of those former Fitbit owners I am alarmed that Garmin is making the same mistake.
Don't be Fitbit/Google and give us the option to go back to the simpler and more useful app.
